    The supporting bar consists of a small strip (1) formed by a hollow body and a connecting part (2) on its narrow side to hold the heddle bar (3) placed at its extremity. These parts comprising the supporting bar are made from flat pieces of sheet steel (4-14) welded together. Relatively thin pieces of sheet steel (5, 6, 9, 10) on the broad longitudinal sides are welded to pieces of sheet steel (4, 7, 8, 11, 12) of appreciably greater thickness on the narrow longitudinal sides. The use of laser welding makes it possible to manufacture precisely and in large quantities a supporting bar of low weight and high flexural strength. Its resistance to alternating bending stresses is notably superior to that of a supporting bar manufactured from a lightweight metal section.

    专利说明:

    The invention relates to a heddle plan with a heddle frame consisting of a carrier lanka and a strap connected to it.
    The purpose of the invention is to increase reliability in operation and reduce material consumption.
    Figs, 1-8 and 12 show variants of the carrier bar, section; 6, 9, 10, and 11 — versions of the bearing of the bar in accordance with FIG. 8, the cut.
    The straightening strap has a hollow body forming the hollow body 1, and also separating element 2 welded to its lower end and located on the latter inner strap 3 for guiding the helium. The design of the carrier plate corresponds to the traditional light metal shaped profiled bar. The carrier bar in accordance with the invention forms a welded structure from flat sheet sections with different material thicknesses, the sheet sections extending along the entire length of the carrier bar. The carrier strip 1 is assembled from the U-shaped curved sheet section 4 forming the upper longitudinal narrow side, and also from the sheet section 5 forming the wide side on the front side, in addition, from the wide section on the reverse side of the sheet section b and forming the lower longitudinal the narrow side of the sheet sections 7 and 8 with a significantly greater thickness of the material. At the same time the sheet section 8 forms the upper longitudinal narrow side of the connecting element 2, which is also made in the form of sections of the hollow body, which are significantly narrower than the carrier bar 1. To make this hollow body, which forms the connecting element 2, the sheet sections 9 and 10, which form wide sides and have a very small wall thickness, are welded to the plate sheet section, as well as and at the lower end are welded to the plate-like body 11. In addition, the sheet section 9 of a material of very slight thickness is also welded to the sheet section 7 forming the narrow side and on the lower edge of the connecting element to profile bar 12, which, like the plate-like piston section 11, has a significantly greater material thickness than the sheet sections 9 and 10 forming the wide sides, EJce the sheet sections 4, 7, 8, 11 and 12 that have longitudinal narrow sides, which have a greater material thickness , provide the flexural rigidity of the carrier bar and
    make it possible to weld wide-sided sheet sections 5, 6, 9, and 10 with a considerably smaller material thickness, this thickness being
    also significantly less than the material thickness of the corresponding wall sections in a traditional support bar made of light metal. Due to this, less weight of the heddle board is also achieved.
    0 To the profile bar 12, the inner bar is welded to guide the harbor 3. This inner bar consists of a sheet portion 13 and a plate sheet portion 14 welded to its upper edge.
    5 Depending on the heblock system, the inner helix bar may also have a different shape or size.
    All sheet sections are assembled by laser welding on
    0 longitudinal wide sides.
    The dotted line shows the four welded connecting lines 15. The welding was done accordingly on the reverse side as well.
    5 For making a heddle bar
    A corrosion-resistant sheet with a small sheet thickness of approximately 0.25 mm is used. The thickness of the material of sheet sections on
    The 0 longitudinal narrow sides are about 1-1.5 mm, i.e. several times larger than thin leafy areas. This design allows for the manufacture of very long heddle plates with high flexural rigidity and a weight that is less than the weight of the support bar of the same length from a traditional metal profile. A material 16 is laid in the hollow space of the carrier bar 1, which fills the hollow space in the form of a sound-absorbing foam material and acts as a protective and retaining body for forming the wide sides of the sheet sections, preventing bulging both outwards and inwards.
    This holding finishing areas on
    wide sides and protective material
    allows the use of leafy areas with
    extremely small wall thickness.
    0 The embodiment according to FIG. 2 differs from the embodiment according to FIG. 1, only in the details at the junction between the non-overlap 1 and the connecting element 2. Forming a longitudinal narrow
    5 side, the sheet section 7 has a recess P on the lower longitudinal edge, into which the upper longitudinal narrow side of the connecting element 2 is inserted. Consisting of the carrier bar 1 and the connecting element 2 of the hedging bar part
    can be even better welded from pre-made separately box-shaped devices.
    Regarding this connection between the bar 1 and the connecting element 2 in FIG. 3 shows another modified embodiment. The longitudinal narrow side of the shoulder strap 1 is formed in this case by the Z-shaped profile 18, the upper shoulder of which forms the upper longitudinal narrow side of the hollow connecting element 2, the sheet sections 9 and 10 are welded to the shoulder of the profile so that the connecting part of both shoulders profile 18 extends obliquely forward upward at an angle of about 6 ° to provide better access to screws (not shown) that pass from below into the heddle bar, for example, for retaining elements of central braces or the like. The inner plate for guiding the heel 3 prevents the activation of such screws, if they extend vertically upwards into the heddle bar.
    The connecting element 2 (Fig. 4) can also be made in another embodiment tapering downwards, so that in this embodiment both sheet sections 9 and 10 are welded at the bottom directly with each other.
    The lower side of the narrow side of the carrier bar 1 (FIG. 5) can be formed by a U-shaped profile 19. A connecting element 2 is welded to one shoulder of this U-shaped profile with both sheet sections 9 and 10. With the other shoulder of the U-shaped profile on a locking nose 20 is formed on the front side for fastening the mounted guides, retaining or driving elements, which are fastened by embracing the carrier bar, as is also known in traditional carrier bars consisting of a lightweight material profile. In a corresponding manner, the locking sock 21 can also be made on the lower edge of the connecting element 2 by appropriately selecting the dimensions of the lower plate longitudinal narrow side 11 of the connecting element,
    It is also possible to reduce the number of leaf sections that form the carrier bar, because the front side of the carrier bar uses repeatedly angled one-piece sheet section 22, which thus covers both longitudinal narrow sides of the carrier bar 1 and the wide side of the carrier bar, as well as the front wide side connecting element 2. Strengthening in order to obtain flexural rigidity is carried out using a welded U-shaped profile 23 mounted on the top. On the reverse side of the other Rianta execution (FIG. 6) may be configured so that the carrier ppanka 1 and connecting member 2 are one-piece extending over the entire height of the flat carrier strap sheet lan ca. 24 vypol0 cepts a common longitudinally extending wide side. This reverse side extending from the entire carrier bar can also be implemented in the embodiments of FIG. 1-5.
    5 In the embodiment of FIG. 7 from the embodiment of FIG. 1 lies in the fact that on the upper longitudinal narrow side of the back U-shaped profile is located shoulders
    0 up. The longitudinal groove between these shoulders is filled with fibrous connective material 25 containing carbon fiber, which is five times lighter than steel. With this material, a very high bending stiffness is obtained and a U-shaped profile with a smaller wall thickness can be chosen. On the lower longitudinal edge between the connecting element 2 and the inner plank for guiding the heel 3, a longitudinal groove is formed, which is filled with fibrous connective material 27, between the connecting plate 2 connecting these two parts.
    5 To achieve weight reduction, in the heddle bar of FIG. 8 in the connecting element 2, at certain intervals in the longitudinal direction, recesses 28 are made, which, in addition to reducing the weight, perform the function of preventing dust from accumulating between the inner bar to guide the helium and the connecting element. These recesses 28 may occur in all variants.
    5 of the embodiment of FIG. 1-7. In the described construction of the strap bar, the recesses of the individual sheet sections can be made in various ways. The cross sections of the carrier bar of FIG. 9,
    0 10 and 11 show three different versions of the recesses, which are made in different ways. After pre-stamping the recess (Fig. 9), the reverse side of the sheet section 10
    5 is formed by deep drawing, so that it surrounds the sheet section 9 of the front wall around the edge of the recess. Then both sheet sections are connected to each other by laser welding. Finally, more
    final finishing of the recess edge.
    The recess 28 (FIG. 10) is manufactured in such a way that the leaf sections 9 and 10 of the front and back side are first cut and the back side sheet portion 10 is superimposed on a mandrel (not shown) with a cross section corresponding to the amount of the recess, and then on this mandrel is superimposed a tire-shaped coating 29. Then the front side sheet section 9 is applied to the same mandrel, and then, finally, the two sheet sections 9 and 10 m of the coating 29 are welded to each other. This prevents dust from accumulating in the intermediate space between the leafy areas of the front and rear sides.
    In order to achieve the same result, in a heddle bar according to FIG. 11, the intermediate space between the front side sheet section 9 and the rear side sheet section 10 is filled with rigid foam 30. Instead, glass fiber reinforced foam in the form of a plate with a recess in it between the two sheet sections can also be laid in this place.
    In order to keep the costs of making the recess 28 in the connecting element 2 as low as possible, the connecting element (FIG. 12) is made from a single strip sheet section that has a significantly greater material thickness than the sheet sections 5 and 6 of the longitudinal wide hollow sides support bar 1. This connecting element 2 is connected to the sheet section 7 forming the longitudinal side of the heddle bar 1, and using a laser-welded weld that forms Wide side not sheer strips sheet portion 6 is welded both to the connecting member 2 and the last portion of sheet 7, which is possible by means of laser welding, and because of low material thickness. In addition, the connecting element 2 is connected by welding to a parallel-running inner inner bar for guiding the sleeves 3 through a profile bar 12 inserted between the inner bar and the connecting piece. In addition, in this embodiment, the number of welded sheet parts is reduced compared to described embodiments.
    In addition, in the carrier bar of FIG. 12 between the longitudinal wide sides of the sheet 5 and 6 of the heald bar
    and the sound absorbing material 16 filling the hollow space 16 is provided with an elastic rubber intermediate layer 31, which is connected to the sheet as well as
    with sound absorbing material. This intermediate layer with a thickness of about 0.3 mm prevents the core consisting of preferably of rigid foam from breaking down on its layer adjacent to the sheet due to a very high load as a result of the rapid reciprocating movement of the carrier bar. In addition, this intermediate layer additionally provides
    5 sound absorbing effect. The intermediate layer 31 may be provided in all the described embodiments in accordance with FIG. 1-11.
    In addition to the high alternating flexural stiffness and relatively low weight compared to the existing heddle plates of a lightweight profile
    5 and other benefits. So, for example, on the upper longitudinal narrow side, threaded bushings can be welded on the inner side in the required place on the inner side in order to fasten the drive plate of the shade. By
    0 compared to solid material from light metal for arranging the threaded holes in traditional bearing strips made from light metal rather small in the transverse size of the threaded
    5 sleeves in a pre-determined location, which also helps to reduce the overall weight. The same applies to the end threaded parts for screw fastening the side frames of the heddle frame, from
