The invention relates to a device for | Prevention of threads on Kreusspuliaechinen · Under pall threads in front of Kreuaspulmcuiohinen] dis feeia l'adsnbrudk "the b" ia Kspsauslami si ^ aiKt is placed on the surface of the Kreux spool, but falling next to the face of the Krus'pule Thread ends, which are also often located around the web bedding. Ia Gegensats "a the oberfläohe on the bobbin & lying yarn ends is the prospect the case yarns already connected in such Hasohinen with Sohnierlgkeiten, the manually operated werdea. In the case of automatic loop pulleys in which the thread end that has run up on the bobbin is searched for and detected automatically, the automatic detection of the drop threads is only possible at least once. To make it easier to open the thread ends of the package, it is very desirable, both in automatic and non-automatic winding machines, to avoid falling threads mx.

Xa At the USA patent 3,156,495 is ready · a device ziu? Prevention of falling threads on such Kareu “winding machines are described in which the winding bobbin is driven by an" ad # introduction ". The solution described consists of

in front of the thread guide drum two eretreocond 3? ad "guide edges are arranged in the direction of the bobbin center. Since these thread guides are attached in front of the thread guide drum, it was great to see the fallies. reduce "ab # r not completely eliminate _f btisch writes the above-mentioned ÜISA patent pamphlet 5 Λ $ & 495 also other Mafinahaen, which serve the aim of avoiding the formation of falling threads" ti. However, none of the previously known measures could prevent the formation of falling threads.

The object of the invention is to »create new means BU find »which fall threads as completely as possible impede. The solution to this problem is geaäß 4er invention is that at least ae before the entire Width of the package swei in the direction of rotation of the package Fai.enfUhrungsJcantea are arranged approximately at the center of the bobbin so that the
