Positive thread feeding device for textile machines

The invention "relates to a yarn feeding device for the positive supply of thread to working elements of Textilma machines.

"Positive thread feed" means the feeding of Thread to a textile machine with a limited amount of thread per unit of time. The textile machine can then only ever Consume just as much amount of thread as the thread delivery device allows.

There are already positive thread feed devices in which the thread zv / ischen a rotatably mounted drum and a pinched and thru the tape looped around the door Circulation of the Bandec is promoted. It is also already

They also have the disadvantage, that between the thread delivery device and the textile machine a great thread of thread; Gegeüe.i pein must: to get a » To avoid tearing of the thread in front of the thread delivery device, the thread ends are drawn into the textile goods. This Long thread path again requires numerous FaaenleituricselG-inents and a space consuming effort for the thread delivery device.

The invention is based on the object of a positive yarn feed device to create that is simple and inexpensive to manufacture and assembled with a small footprint can be. To solve this problem is the invention Thread delivery device characterized by a with constant, with the working cycle of the working elements of the textile machine synchronous speed drivable drum on that of the thread coming from a supply reel in tangential Direction windable and from which the thread in as well tangential direction can be developed, and by an im Inside the drum rotatably mounted disc, which with radial arms through longitudinal slots of the drum shell to the outside engages, the disc is constantly held in a plane that forms a small angle with one perpendicular to the drum axis Including extending plane, and the thread is fed in the area of the disc, so that the thread turns be displaced by the disc in the axial direction of the drum.

In the case of the thread feeder according to the invention, the shifting of the thread windings by means of the inclined disk along the transport melt partially creates a store of lids on the drum, so that if the fador in front of the thread feeder breaks, there is no danger of it the loose thread end sucked into the textile product vrirc ^1. = T- ¹ ? the supply of thread accumulates on the drum, no precautions need to be taken to ensure a long thread path between the delivery device and the processing tunnel. The Vorx-ichtung can therefore be accounted for with little space requirement. It is also simple in construction and inexpensive to manufacture.

One embodiment of the invention is in the singles Figure of the drawing shown, which shows a side view with ■ beilweisem vertical section.

In the drawing, 1 is a Trozsnel which are arranged from a iir.teren cover disc la _i a o "Beren DecVscheibe Ib and the cover plates connecting is"'"rods 1c to each other. The rods are äng on Trommelua ^ a spaced 1d, so that the drum 1 forms a sort of rod cage. the drum 1 is rotatably mounted on a shaft 2, which is non-rotatably held in a direction indicated at 3 frame. on the axis 2, a pulley 4 is also rotatably connected via driver 5 with the thread drum 1 .

In the interior of the thread drum Λ , a disk 6 is mounted which, with radial arms 6a, reaches outward through the spaces 1d between the rods 1c. As can be seen from the drawing, includes the plane of the disc 6 having a vertically extending to the axis 2 an angle ot a level E, which may be on the order "of 1O ° bis3CP, ie ^ disc
