    1533160 Depositing strand in cans BARMAG BARMER MASCHINENFABRIK AG 5 March 1976 [7 March 1975 9 Sept 1975] 08888/76 Heading D1F A strand 2 which is travelling at over 1000 m/min enters rotating guide tube 1 and is deposited by it in can 11 in the form of helical windings. The entrance to the guide tube is on or substantially on the rotational axis 14 of the tube. The tube is curved in both the vertical and horizontal planes. The tangent to the guide tube at its exit is at an angle #=30 to 80‹ to a radial line drawn to the exit from the rotational axis. The radius of curvature # of the guide tube at its outlet is given by wherein r is the distance between the exit and the rotational axis and Á is the coefficient of friction between the strand and the guide tube, substantially all of the kinetic energy of the strand is thereby lost before the strand leaves the guide tube. Preferably the tangent to the guide tube at its exit is inclined downwards at an angle of 5 to 30‹. The can 11 is reciprocated at 1 or rotated to facilitate uniform deposition of the strand. In the embodiment of Fig. 3 the guide tube 1 is arranged within a rotor 18 comprising two truncated cones with their bases touching. An annular nozzle 5 located just above the plane at which the two cones touch directs a stream of air downwards to reduce the air resistance experienced by the strand as it is laid in the can 1 and to avoid generating a low pressure region under the helix. A cage 6 of bars 15 is provided to limit the diameter of the strand helix during the start up of the strand feed. The cage may take the form of a truncated cone of bars or a solid-walled tube. In the embodiment of Fig. 5 the rotor has three inwardly inclined ducts 21, 22, (23, Fig. 6, not shown) which open into a duct 24 which is coaxial to the rotational axis and also extend to an annular nozzle 5. Air is blown in the directions shown.

    where R is the radius of curvature of the lower part of the tube; g is the radius of the trajectory of the movement of the lower end of the tube; a is the angle between the projection of the lower end of the tube on the horizontal plane and the tangent prozoned in this plane to the convex surface of the tube through the extreme point of the projection of the end. The device comprises an annular nozzle placed near the level of the outlet of the tube and concentric with its movement trajectory and having outlet openings fixed downwards. The housing has the shape of two cones mating with large bases and is vertically mounted rotatably around a vertical axis, with the guide tube placed in the housing and its outlet opening located on its outer surface, and the annular nozzle mounted outside the housing is centered around it. The housing has a downwardly extending axial channel in communication with the annular nozzle through the side channels. In addition, the device has a round protective grille, made of vertically arranged rods. The rods are mounted with the possibility of adjusting the position in the radial direction of the grid. Pa figs. 1 shows the proposed device, top view; on fng. 2 - the same, front view; in fig. 3 shows an embodiment of the device; in fig. 4 - vectors of the harness accelerations as it moves in the lower part of the guide tube; in fig. 5 shows a housing for placing a guide tube, a slit; in fig. 6 - the same, top view. The device comprises a guide tube 1 mounted by bearings 2 above a container, for example, a basin 3, which can be rotated around axis 4 from an actuator 5. The tube entrance 6 is placed on its rotation axis 4, and the lower end 7 of the tube is radially relative to its path 8 movements with a radius of g. Tube 1 is spatially isogouti and radius R of curvature along its length is non-permanent. The projection of the lower end of the tube 7 to the horizontal plane is with a tangential 9, carried out in this plane to the convex surface of the tube through the extreme point 10 of the projection of the end, an angle a equal to 30-80 °, and the projection of this end and the vertical plane is located to the corresponding tangent at an angle p, amounting to 5-30 °; its optimum value is 15 °. The radius R of the curvature of the engineering part of the tube 1 is determined by the condition that the transporting line of the conveyor harness 11 chemical fibers with a tangent 9 to the lower end of the tube and the force of the cable to rub the tubes to prevent it. clogged This radius is determined from the relationship:,. WITH; 2 - sin: where 1 - the coefficient of friction of the fibers on the tube. Practically, R approximately makes up 50-90% of g, and large amounts of R are advisable when laying a bundle of fibers with high humidity and averaging large values of angle a. When calculating the ratio, we used the accelerations experienced by the rope at the exit of the tube, where ui is the Coriolis acceleration vector, a2 is the relative acceleration vector, us is the centripetal acceleration vector, ap is the resultant real acceleration vector, and St is the resultant theoretical acceleration vector (Fig. 4) . Near the level of the outlet opening 12 of the tube 1 and concentric with its movement trajectory, an annular sonlo 13 is placed, with the outlet openings 14 directed downwards (Fig. 2). The tube 1 can be placed in the cornea 15, which forms the shape of two bodies mated with large bases and vertically installed with rotatable rotation around the vertical axis 4. The tube outlet port 14 is located on the outer surface of the body 15, and the annular nozzle 13 is mounted outside the body concentric to it ( Fig. 3). A circular protective grid is placed around the body, consisting of vertically mounted with the possibility of adjusting the position in the radial direction of the grid of rods 16. The rods 16 can reach pelvis 3 and occupy an inclined position with giving the grid an expanding downward conical shape. The height of the cage is 2-10 steps A turns 17 of the bundle to be laid. Instead of a lattice, a closed hollow cylindrical or conical body with sound insulating layers can be used. It is possible to perform in the housing 15 an expandable downward axial channel 18, which is connected with d annular nozzle 13 by means of three lateral channels 19 (FIGS. 5 and 6). When the tube 1 is rotated from the actuator 5, the feed pair of rollers 20 gut 11 chemical fibers are transported through the tube and placed in it
    the form of turns into a rotating pelvis 3. In order to prevent contact between the turns between themselves in the process of laying and exposing them to unwanted air flow, their step A must be at least 10-20 mm. The radius B of turns is determined by the values of the angles a, p and the radius r.
    The tube 1 rotates with such a frequency that the ratio of its circumferential speed to the diameter of the turns 17 is approximately 5–20% faster than the speed of the tow cable to the tube, which ensures the stability of the turns in space.
    In order to feed the harness to the tube when the device is put into operation or to transport the harness in a steady state, if the harness is placed with high moisture content, an injector can be used (not shown in the figure).
    The air note coming out of the ring soyl 13 partially compensates for the air resistance experienced by the turns of the harness coming out of the tube, thereby preventing the winds from coming into contact with each other.
    In the embodiment of the device according to FIG. 3, the air flow exiting the nozzle 13, streaming the outer surface of the rotating body 15, first expands and then its diameter decreases and, due to the rotation of the body, receives a pulse of movement of a circle. Due to this, the air flow contributes to the movement of the turns of the tow.
    The presence of the housing 15 makes it possible to eliminate the stagnation zone under the tube, improve the aerodynamic properties of the device and increase its rigidity, and the grill serves to limit the diameter of the turns of the rope and to enclose the rotating parts of the device.
    When an axial channel is made in the body, it becomes possible to eliminate the vacuum zone under the body by blowing it out with air supplied through the side channels.
    The values of the angle a and the radius R of the curvature of the tube contribute to the creation of forces that allow the harness to move through the tube without clogging it and the motion of the tow when it leaves the tube along the trajectory of its lower end.
