Abstract

The invention relates to textile mechanical engineering, can be used on a weaving machine, and allows for increased reliability in operation. Returned vrap1ate. The first movement of the wa.ch 10 is transmitted by the transmission II through the pulleys I2 by the driven gear 5. which, reciprocally, rotates the first movement, the shock, -1c, but by the guides of the 1st knife 7 and the 8th toothed belt 4. When the toothed belt 4 is moving, it is driven the movement coupled to it by means of the projections 3 of the shuttles 2, moving in the guide I.

The pulleys 5 are connected between the co6oii and the drive shaft 10 by means of gearing 1 1 and pulleys 12.

The device works as follows.

The gearing device of the weft yarn (Figs. 3 and 4) has a toothed belt with protrusions on the outer and inner surfaces, with the help of which it contacts the shuttles 2 and the driving 5 and the guides 7 and 8 . In order to tension the toothed belt 4 and adjust its engagement with the hook 2, the pulleys 8 are mounted for movement. By increasing the number of hooks of the shuttles with the toothed belt, the reliability of the transmission is improved, the intensity is reduced, and the dynamic loads in the kinematic units of the device are reduced.

Claims (4)

Invention Formula I.
