Description

The ginning drum 1 is rotatably mounted in the housing 2, which is attached to the textile machine, namely, the knitting machine, in which the number of devices corresponds to the number in the sewing systems of the machine.

The drum 1 is driven through a pin wheel 3 with a perforated belt (not shown). Thread H passes through brake 4, disc brake 5, thread monitor b and then winds up tangentially on drum 1 rotating in the direction of arrow P. The latter has an inclined disk 7 which moves the threads in axial direction so that an intermediate stock is formed on the drum

Further, the thread through the brake ring 8 is retracted through the lower outlet edge 9 of the drum 1.

Coaxially with the axis of the drum 1, an output thread guide is installed, the peephole of which is two ears 10. Another thread monitor 11 is connected to it.

The ears 10 and the thread monitor 11 mounted on the bracket 12, mounted in the housing 2.

Under the outlet edge 9 of the drum 1 on the bracket 12, a hook 14 is installed by the sleeve 13, which can occupy two positions (Fig. 1 and Fig. 2), while the sleeve 13 rotates around the bracket 12. To fix the position on the hook 14, latch 15 interp position.

In the position shown in Fig. 1, the hook 14 interacts with the thread N. The zel of the hook is open in the direction of the scientific research institute of the rotation of the drum 1 along arrow R. The filament H is removed, which, due to the tension acting on it in the direction of removal, is opposed the direction of rotation of the drum 1 at its outlet edge 9, is placed inside the open mouth of the hook 14, which prevents its lateral movement around the outlet edge 9. Therefore, such amount of thread H is removed from the device, which frees the drum due to its rotation in the direction of the arrow P.

Thus, the rate of release of the thread is limited by the speed of its winding. This is typical for operation of the device in the continuous feed mode.

If, when adjusting or repairing a machine, the thread must be pulled out from intermediate stock V, the hook 14 is moved to the position shown in figure 2, in which it does not interact; with thread. The thread can be removed from the bottom of drum 1 in any way. In this case, the removal rate does not depend more on the winding speed, and then the thread-feeding device can be used to periodically feed the thread during continuous operation.

Claims (2)

1. A thread-giving device for a test machine, in particular in a hall, containing a case, a rotary driving accumulator with a braking ring is installed in it, an output thread guide, the peephole of which is located СООСНО with a thread accumulator AND located between the brake ring and the output thread guide filing mode mounted on a bracket that can be moved in two positions, in one of which it interacts, with a thread to ensure yarn feed and in the other does not interact with the thread to provide periodic thread feeding, characterized in that, in order to simplify its maintenance, the bracket with the element for changing the thread feeding mode is fixed on the body next to the thread-storage drum, and the element for changing the mode the feed of the thread is made in the form of a hook, the shed of which is directed in the direction of rotation of the thread-storage drum. 2. The device according to claim 1, wherein the hook is attached to the hub mounted to rotate relative to the bracket, and its position is fixed to the hook relative to the bracket.
