    A knitting machine has at least one needle bed equipped with longitudinally displaceable needles controlled by a needle cam curve, and between the needles are protruding sinkers controlled by a sinker cam curve. The sinkers are movably supported in at least the longitudinal direction of the needles and being controlled such that at a given feed, after the locking in of the yarn, they are moved counter to the lowering movement of the associated needles and after casting off of the loop are moved counter to the needle raising movement. The needle and sinker cam curves have adjoining steadily curved arc portions that in the case of the needle cam curve are sinusoidal and merge steplessly with one another. To reduce noise and wear, especially at very high knitting speeds, the sinker cam curve is substantially sinusoidal, at least in the loop forming zone.

    The invention relates to a knit machine industry, namely to the design of knitting machines.
    The purpose of the invention is to improve operational reliability and expand technological capabilities.
    Figure 1 schematically shows a circular knitting machine in an axial section through the needle cylinder and the corresponding key box, side view; Figures 2 through 7 show variants of the relative position of the channels of the needle and platinum locks; Fig. 8 shows channel configurations of needle, platinum and slide locks, ocHanteH with slotted needles of a circular-knitting machine; Fig. 9 illustrates the points of the process of looping with the slot needles,
    The needle cylinder i of a circular loader usually has a rotary support around the vertical axis of the stationary support ring 2 and is driven into rotation from a driving source (not shown). A cylindrical locking box 3 is fastened on the support ring 2, which on its side turned to the needle cylinder 1 has control elements for tongue needles and curling and dumping plates 5.
    The radial grooves of the needle cylinder 1 located at a distance of the needle step are placed with longitudinal bridges 6, of which each side is provided with a guide surface 7 on its radially outward side, on which it is supported with its tail part 8 of the zychkov needle 4 On the longitudinal jumpers 6 are fixed snugly on the side, auxiliary jumpers 9, which only partially extend along the length of the longitudinal jumpers 6 and are provided only in the lower part of the needle cylinder Refer to I. and to circumstances, two adjacent supporting webs 9 bounded guide groove of the needle, which is introduced into the tail side portion 8 of the tongue of the needle.

    the channel of the needle lock 11, which is made correspondingly valid in the dp1p5 case krino11, which controls the longitudinal movement of the needles 4,
    At the same time, on the lock box 3, there are several channels of needle-fo of lock 11, Pa, lib, 11c located above each other, which interact with the corresponding points 10, 10a, lOb, 10c of needles 4, the tail parts 8 of which have different lengths to The separate needle positions corresponded to the individual channels of the iglo lock from 11 to 11 s, as is known for the choice of the pattern.
    Auxiliary jumpers 9 end with a position 12 approximately at the top bounding the uppermost locking channel 11 of the part 13 of the needle lock. At the top of the auxiliary slips (9), there are located cooler and discharging platinum 5, the tail parts 14 of which are made in the form of two shoulders. Each platinum tail section 14 carries, on the side rotated from the plate top 15, protruding radially outwardly towards the string 16, which cooperates with a channel of the platinum lock 18 that is made on the inside of the lock box 3 and part 17 of the platinum lock, which controls the longitudinal the direction of the needles by the longitudinal movement of the procuring and dropping platinum 5.
    On the side rotated from platinum 16, each platinum tail section 14 bears a roughly triangular, protruding, protrusion 19, which has a circular support surface 20 on the base of the annular groove 21 formed in the needle cylinder 1 when the the oscillating support so that the skimming and dumping platinum 5 can oscillate around the horizontal axis of oscillation, according to the movement of which the upper part 15 of the platinum carries out a generally rectangular relative direction longitudinal movement of the needles, reciprocating, transverse movement.
    This transverse movement is carried out by two curved platinum control surfaces 22 and 23, which are located on the inner side of the lock box 3 on portions 24 and 25
    of the platinum lock, of which one part 25 of the platinum lock with its curved surface 23 of the platinum etching below the support lug 19, and the other part 24 of the platinum lock with its curved surface 22 of the platinum control of the supporting protrusion 19 affect the control strip 26 or, respectively, on the tail section 14 of the currently active, extinguishing and resetting platinum. At least the upper portion 24 of the platinum lock is capable of radial movement by means of the designated position 15 distal, i.e. the harmonic character of the 27 is activated by sleep-. The brushstroke, which in FIGS. 3-9 is represented by an eccentric actuating flap, is slightly higher than the length of the mechanism period 39, while for axial displacement, it provides a lengthwise corresponding length in the intake device. According to a variant, the platinum-17 part of platinum-20 Zii’s structural movement in FIG. 2 has an amplitude of this sine-lock which is provided with an actuated, eccentric actuating device 28. Both actuating devices 27 and 28 provide longitudinal and transverse movement of the interrupting and dropping platinum 5, respectively, acting in In this case, the requirements. Motion control
    The long curve is chosen so that the double amplitude of the curve of the needle lock 29 is equal to the hinge length of the tongue needle 4 and 25 in this way. The needle stroke 31.
    The curve of the platinum lock 30 is purely sinusoidal, i.e. harmonic curve, which is relative to the sinusoidal curve of the needle feed of the reed needles 4, as well as the fixed lock 29 is out of phase by
     ° so that the curve of needle in the longitudinal direction of the needles, the longitudinal movement of the cooler and dumping plates 5, is carried out according to the curves 2 or 30 of the needle lock or the platinum lock represented in FIGS. 2-7. The transverse movement of the damping and dumping plates 5 is controlled by the interaction of the support protrusion. PA 19 tail plate platinum 14 with an annular groove 21, developed from the outer surface of the needle cylinder 1.
    The tongue needle 4 (FIG. 2) in its longitudinal direction is movable relative to the needle stroke 31, which passes between the lowest point located on line 32 and located 35

    The sinusoidal curve of the platinum lock 30 passes in such a way that the cutting edge 42 (FIG. 1) of the cooling and dumping plates 5, which follows the curve of the needle lock with 30, with the cutting and discharge platinum 5 in the lowest position, is at a safe distance 43 below line 32 and hence the end of the open tongue

    around the hinge axis 36 in the manner known for tongue needles.
    Between both 32 and 33 extreme points 37 and
    38, according to the position of the circular movement and the position of complete removal, the tongue needle 4 follows in its movement along the curve of the needle lock 29, which in FIG. 2 has a sinusoidal, i.e. the harmonic characteristic, which in figure 3-9 is presented slightly higher than the length of the period 39
    according to the length of the intake device. According to a variant of the construction curve, it is chosen so that the double amplitude of the curve of the needle lock 29 is equal to the hinge length of the tongue needle 4 and thus the stroke 31 of the needle.
    The curve of the platinum lock 30 is purely sinusoidal, i.e. harmonic curve, which is relatively sinusoidal curve needle ° so that the curve of the needle lock

    The sinusoidal curve of the platinum lock 30 extends in such a way that the cutting edge 42 (FIG. 1) of the cooling and dumping plates 5, which follows the curve of the needle lock 30, when the cutting and discharge platinum 5 is in the lowest position, is at a safe distance 43 below the line 32 and from here the end of the open tongue

It follows from the sum of the safe stroke 43 and indicated by the position 48 loop lengths
    The tongue needles 4 with their open hook 34, in the presence of the needle cylinder 1 movement indicated in arrow 49, in which they pass the curve needle lock 29, in the process of their outgoing from the position 38 of the complete removal of the feed movement, take the position indicated 50, which is fed from the yarn feeder which they, in conjunction with the cooler and dumping platinum 5, form a loop 52 in the kuler zone 51.
    For a detailed review, the process of forming the loop of the curly zone 51 is divided into separate partial zones b-g (Fig. 2), to which, even before the beginning of the actual smoking process, there is an adjacent partial zone a. Each of these partial zones corresponds to a given class of knitting machine, for example, 28 class (28 needles and 28 quilling and throwing plates for one English inch of the length of the needle cylinder). step needles or platinum.
    In the first partial zone, the needle needle 4, with its hook 34, begins to grab the thread 50, while the neighboring cooler. and the ejecting platinum 5 CBO5-SU1 with a quivering edge 42 is connected to the filament 50 and coming into contact with it.
    In the partial zone b, the zychkovy needle 4 begins the formation of loop 52, while the thread 50 abuts against the cooling edge 42 of the left adjacent smoking and reset platinum 5. The needle 4 located in the partial zone precurses the thread 50.
    In the partial zone d, the zychkovy needle 4 there already formed a loop 52 of full length 48. In the subsequent partial zone e, loop 52 has approximately the same maximum length that was reached in the partial zone d. In this case, the thread in a small amount can be subjected to reverse retraction and the already formed loop b of the partial zone f | 3a due to which the loop in this partial zone f reaches its final length and at the same time the alignment of the thread tension and the uniformity of the formed loops are achieved. Finally, in a partial ch g, the looping process is completed.
    The curve of the needle lock 29 and the curve of the platinum lock 30 according to the design variant shown in FIG. 3 are identical to the design variant in FIG. 2. Compared with the variant in FIG. 2, the tongue needles 4 and cupping and shedding platinum 5 in FIG. In the culinary zone 51, the hilt is shifted to the side by half the needle pitch or the platinum pitch relative to the lock curves 29 and 30, which is achieved by means of the corresponding turning of the lock box 3 relative to the needle cylinder 1 in FIG. This mixing leads to the fact that in the kulirnaya zone 51, the length of the loop at the highest point of the curve of the needle lock 29 is the greatest (partial zone c).
    From a comparison of the passage of the yarn in the kulir zone 51 in Figures 2 and 3 it follows that by means of the above mentioned mixing between the locking curves 29 and 30 and the tongue needles 4, as well as by the quenching and dropping platinum 5, looping can be influenced. and from here to the (small) amount of thread, which, when the thread is pulled to the loops, returns back, looking at the circumstances, the number of loops already formed. Depending on the currently interlaced pattern and the yarn used, this offset can be selected so that the optimal ratios are obtained.
    The variant in FIG. 4, compared with the variant in FIG. 2, shows that the stroke 44 of the platinum remains unchanged while the safety distance 43 automatically becomes longer and, due to the vertical displacement of the curve of the platinum lock 30, a shorter length of 48 occurs as a result. loops.
    In addition to the vertical displacement in FIG. 4, the curve of the platinum lock is displaced in the circumferential direction of the needle cylinder 1 by an amount of 53, with both locking curves 29 and 30 consistently keeping their shape. The offset value 53 can also be set to be larger or smaller than that shown in FIG. 4, it can be
    also relative to the vertical line 41, lie to the right.
    Figure 5 presents the same option as in figure 2, however, in the presence of a reduced length in the hall device, i.e. the period length 39 is a sinusoidal curve of the needle lock 29 and equally sinusoidal curve of the platinum lock 30,
    Fig. 6 shows the same curve of the needle lock 29 as in Fig. 5, while also based on the same period length 39. However, the tongue needles used have a shorter hinge length 31 with the result that the safety distance 43 Because of the remaining same stroke, the 31 d needles must be larger in magnitude, as the maximum length of the loop is necessary (distances 43 and 48 in FIG. 5 are the same in magnitude).
    Basically, it is possible to make the stroke 31a of the needle smaller than the hinge length 31, and thus accordingly increase the stroke 44 of platinum.
    The curves of the needle lock 29 and the curves of the platinum lock 30 shown in FIGS. 2-6 are purely sinusoidal curves.
    The curve of the needle lock 29 (Fig. 7) in the area of the points 37 and 38 of the turning movement of the needles is purely sinusoidal. The sinusoidal section of the arc in the zone of the upper turning point or the extreme point 38 passes between both points 54 and 55, while the equal in size sinusoidal section of the arc in the zone of the lower turning point or extreme point 37 begins only according to position 56 and figure 7 shows only half. Between points 55 and 56 or respectively 54 and 57, i.e. at the edges of the needle-lock curve 29, the sinusoidal curve approaches the straight lines, which are tangent to the adjacent sinusoidal sections of the arc at 55 and 56, or respectively 54 and 57. Connecting areas with a slight continuous bend can also come forward, if it is appropriate in individual cases. However, a tactile continuous attachment of a downward arc to the adjacent areas at 40 points of movement should be ensured.
    Additionally, a different deviation from the sinusoidal shape of the needle lock 29 and the platinum lock 30 curve is provided in the kulir zone. Between the two sinusoidal successive parts 0 of the lock curves provided along the length 58, the lock curves 29 and 30 with horizontally passing as tangent are continuously adjacent to adjacent sinusoidal arc sections. The straight sections of the lock curves 29 "and 30a are located inside the kuler zone at the points of maximum amplitude of the curve of the needle lock 29 or, respectively, the curve of the platinum 20 lock ZO. They allow, in the cooler zone 51, a fully elongated loop 52 to maintain along its length above a certain zone. The straight sections 29 "and 30a of the curves, according to the requirements currently in force, can be chosen of any length: their length usually ranges from 0.5 to 2 needle steps.
    It is permissible if only one of 30 of the two lock curves 29 or 30 has such a straight section 29 o or 30 a curve inside the cheek zone 51, while the other locking curve instead has an arc curve along the length 58, which approximately complements the harmonious shape of the curve.
    In order to better understand the sinusoidal sections of the arc of the needle-lock 29 and the curve of the platinum lock 30 (Fig. 7) with respect to these two lock curves, the arc of a circle is represented with the position 59, from the projection of which 45 sinusoidal curves finally occur.
    The control of the tongue needles 4 and the choking and dumping plates of 5 circular machines (Figures 1-7) also allows 50 knitting machines or dressing machines, which work with other types of needles, for example, with hook or groove needles, to be used. The use of slotting needles is shown in Figures 8 and 9. 55 In this case, only individual lock curves are shown in Fig. 8, while Fig. 9 shows the relative position of the mortise needle relative to the corresponding curling and dropping platinum during the looping process.
    The ratios, for example, are basically similar to the ratios according to the circular knitting machine of FIG. 1 with the only difference that below the needle lock 13 there is another sliding button in the lock box 3 that controls the moving part of the slot needles, for example , in the place of the lock channel Pa presented (fig.) and interacts with the corresponding heaps of the sliding parts.
    The curve of the needle lock 29 and the curve of the platinum lock 30 of the slider needles, one of which is represented in FIG. 8 (in section) by the position 4h, are identical to the embodiment in FIG. These are both sinusoidal curves, the same positions denote the same parts. The lock curves 29 and 30 can be offset relative to each other both in the vertical direction and in the horizontal direction, with the shape of the curves itself remaining unchanged.
    However, in the sinusoidal curve of the needle lock 29 c, to the equally sinusoidal curve of the platinum lock 30, another third of the curve of the sliding lock 60 is added, which serves to control the moving part 61 of the 4Qo slot needles. The curve of the sliding lock 60 becomes effective, basically only the corresponding sinusoidal a half wave of the needle lock curve 29 in the second half of the length of the period 39 (FIG. 8). In this zone, the curve of the slide lock is purely harmonic (sinusoidal).
    In order to prevent the slot needles 4a from accelerating the moving part 61 too fast at the beginning of the process, the curve of the movement lock in its growing branch can have a trajectory marked with a high position, which begins with the strokes from approximately the first quarter of the length of period 39, resulting in soft acceleration of the engine part 61.
    Mutual positioning of the mortise needle 4a, the slide part 61, and the adjacent sticking and dropping platinum 5 when controlled by means of a lock 5
    The curves 29, 30, and 60 can be seen in Fig. 9, with the current positions of these loop-forming organs, respectively, sections, and the A-G lock curves 29, 30, and 60 in Fig. 8.
    In position A, the slotted needle 4o (located at its lowest position of the institute), the hook 34 is locked by means of the slide part 61. The chewing edge 42 of the damping and dropping platinum 5 is located at a distance corresponding to the longest 48
    5 at the top of the 34 needle hook. The quenching process is completed.
    In position B, the slot needle 4o (is already in the movement of removal, while the quivering and dropping platinum 5, relative to position A, performs the opposite movement in the direction. Dvizhkova part 6 did not change its position, In position C, the slotted needle 4o (
    5 is almost completely removed, the cutting and dropping platinum 5 descends further in a counter-movement relative to the position B, while the sliding part 61 still has a stationary support,
    Finally, in position D, the slotted needle 4 "has reached its position of complete removal according to the extreme point 38 of the sinusoidal curve while the quivering and dropping platinum 5 equally reach its lowest extreme point 40 corresponding to the sinus curve. Dvizhkova part 61 always
    0 has a support in its lower position. In position E, the slotted needle 4a with its hook 34 catches the thread 50, which began its movement, while the cooler and dumping plates 5 are removed in the opposite direction. The dvig part 61 shifts and begins to close the needle,
    At position F, the slot needle 4 0 (0 is lowered approximately half the way from its position of complete removal, while the quill and 1 drop platinum 5 approximately half of its way lifts 5 from its lowest position. Dvizhkova part 61 is completely withdrawn and I closed the hook 34 of the needle. In this case, the loop pad on the slider part 61 is in place.
    eleven
    and finally, at position G, the same state is again reached, as is the case at position A, the process of cheating is completed.
