Description

The invention relates to devices for braiding a lengthy product, in order to maintain from sagging, for example, cable, hose, etc., and can be used in machine-tool construction, mechanical engineering and aeronautics.

The aim of the invention is to ensure the stability of the tension of the thread-like material and the automatic shutdown of the device when it is strongly weakened or broken.

Such a constructive solution ensures the stability of the tension of the threadlike material and the automatic disconnection of the drive package and winding device.

The step of braiding the threadlike material removed from the coil causes the coil to be retarded with respect to the ratcheting of the ratchet wheel 3.

Tension control of the filamentary material is provided by a brake including a spring element 5 with a friction disk 4.

When the movement of the traction cable of the pack 24 is changed to the opposite, the lead 9 connected to it by means of the gear wheel 8 rotates in the opposite direction. Ratchet mechanism opens. The ratchet wheel stops and brakes the brake pressed against it.

The device for winding and unwinding the latch 13 on the lead-spiral oPlate from the thread-like material onto the lead 9 engages with the disc of the ratchet wheel 3 and causes the roller 6 pressed against the spring element 5 through the friction disk 4.

The leash 9 and the associated roller, comprising a housing, a mandrel for mounting the thread-type roller, a leash, a brake with a friction disk for adjusting the thread tension, a ratchet mechanism, the link of which is connected 12 and 20, rotate and guide the springs. - "| Q with a friction disc of the brake, and a stubborn roller-like material 23 on a moving sleeve, characterized in that, in order to

The bundle traction cable of the package 24. ° ensures the stability of the tension of the thread. The threaded material thrown through the supporting visible material and automatic disconnection 20 presses the device with its strong weak-double-arm lever 10 with an emphasis 19 to the post and the cliff, it is equipped with a two-arm leash 9 and extends the return 55 spring-loaded lever with a roller onto the single spring 22. end mounted on the thrust

Due to the difference in the circumferential length of the sleeve, the current-collecting mechanism, microbag 6 and the length of the helix on a single switch which is located opposite

The step of braiding the threadlike material removed from the coil causes the coil to be retarded with respect to the ratcheting of the ratchet wheel 3.

Tension control of the filamentary material is provided by a brake including a spring element 5 with a friction disk 4.

When the movement of the traction cable of the pack 24 is changed to the opposite, the lead 9 connected to it by means of the gear wheel 8 rotates in the opposite direction. Ratchet mechanism opens. The ratchet wheel is also stopped by the oral braid.

A short-term slight weakening of the tension of the thread-like material at the time of the reverse movement of the package is compensated by a spring 22 connected to the two-fold lever 10. The magnitude of the tension
