Abstract

The invention relates to textile industry, in particular to the manufacture of non-woven tapes used in the manufacture of reinforced plastics, and improves the quality of the tape by increasing the density of transverse threads while maintaining a high connectivity of the threads. The threads 15 are divided into two groups, one of which is fed into the opening of the ring 2, and the other, bypassing the ring 2 and the body 1, is fed, like the first one, onto the mandrel 16. In this case, the threads passing through the ring 2 are wound with threads the longitudinal reinforcement from the spool 7 mounted on the ring 2, with the simultaneous transfer of groups of threads after the next insertion of the longitudinal reinforcement. This is ensured by the presence of a device for moving the transverse threads into the opening of the ring 2. 1 Cp. f-ly, 9 ill. with $ (L D. -1 75 /

Description

one

The invention relates to the textile industry, in particular to the needing of non-woven tapes used in the manufacture of products from reinforced plastics.

The purpose of the invention is to improve the quality of the tape by increasing the density of the transverse threads while maintaining a high connectivity of the threads.

FIG. 1 given the device, a general view, - in FIG. 2 shows section A-A in FIG. in fig. 3 shows a section in FIG. 2; in FIG. 4 is a view of B in FIG. one; in fig. 5 is a view of FIG. one; in FIG. 6, sections DD-E, E-E, LC-1, AND-I in FIG. 5. Accordingly.

The device comprises a housing 1 for a head mounted on a frame in which a ring 2 is mounted on sliding or rolling bearings with a fixed gear fixed to the driven gear 3. The ring 2 is rotated by means of the driving gears 4 through bevel gears 5 from the actuator 6. ring 2 has a spool 7, the thread 8 with which is wound through the thread conductor 9. On the frame (not shown) is fixed on the bearing supports 10 a device for moving the transverse threads in the hole of the ring 2 having a crankshaft 1 1 on the connecting rod Their necks are rotatably mounted with the thread conductors 12. The rotation of the crankshaft 11 is provided from the actuator 6 by means of a rigid kinematic connection with the ring 2 and can be carried out by a gear conical gear 13 mounted on the shaft 14, by incorporating into this kinematic a chain of Maltese or cam mechanism (not shown), ensure the ball, its accelerated periodic rotation of the crankshaft 11 through an angle of 180 ° with the next stand in the received position until the next turn of the ring 2 Body 1 and the ring C0 2 have radial slits for the passage of transverse threads 15, and the cut in ring 2 is somewhat wider than the cut in housing 1. Since the driven gear 3 also has a cut leading gears 4 that engage with it, there must be at least two. The finished ribbon is wound on a mandrel 16, mounted on the station.

The device works as follows.

The transverse threads 15 pass through the openings of the thread conductors 12 and are divided into two groups, one of which is fed into the opening of the ring 2, and the other bypasses the ring 2 and the body 1. Both groups are already wound in the finished tape with the corresponding tension on the mandrel 16.

At the same time, with the aid of the actuator 6, gears 5 and gears 3 and 4, ring 2 with spool 7 rotates around a group of threads 15 that pass through the hole of ring 2. When in the process of turning ring 2 the slots in it and in case 1 are aligned at a width equal to the width of the belt, the crankshaft 11 rotates rapidly. The slot in the ring 2 is wider than the slot in the housing 1, so that during the movement of the spool around the circumference of the corresponding angle cL (figure 2), the crankshaft 11 with ring 2 turn 180. When the crankshaft 11 rotates, the hinged thread conductors 12 under the force of tension of the threads 15 rotate on the crank journals and provide with this the possibility of changing the positions of two groups of threads 15 changing at this place 1, after which the shaft 11 in this position stands until the next alignment of the slots of the ring 2 and housing 1.

The thread 8 from the spool 7 again wraps the upper group of threads 15 by rotating the ring 2, and so on. As a result, a semi-woven ribbon is formed (Fig. 5).

In the belt formed by the device, the transverse threads, no matter how dense they are, are connected with each half-turn of the longitudinal threads. The length of the longitudinal threads in the tape is more defined, rigidly fixed, since each subsequent half-thread is woven into the structure of the formed tape.

I

Due to the indicated features, the device made by the device has a structure (Fig. 5) in which: the upper half-threads of longitudinal threads, unwinding from the spool mounted on the ring, are laid on all transverse threads (Figs 7 and 9), and the lower half-turns form ducks (Fig. 6 and 8), as if stitching the transverse threads divided into two groups.
