Embodiment Construction

[0043] figure 1 The shown yarn length-measuring feeding device F basically corresponds to the length-measuring yarn feeding device known from the patent document WO-A-02 / 33157, and has a housing 1 containing a not shown Drive motor for winding assembly 2. A yarn storage body K is fixed on the casing 1 . Said winding element 2 is driven rotatably about a substantially cylindrical yarn storage surface 6 of the yarn storage body K. The yarn storage body K has an axis X and has a fixed or variable diameter. At least one brake device S with a brake pin 3 is arranged close to the housing 1, the function of the brake pin 3 is to cooperate with the yarn storage body K to measure the number of winding yarns, and the winding yarn is unwound in one operation will be released separately. Said winding yarns are produced with the help of the winding element 2 and are stored intermediately on the yarn storage surface 6 so as to be in direct contact with each other or separated axially fr...

Abstract

Disclosed is a thread-measuring feeding device (F) comprising a stationary storage member (K) which defines a substantially cylindrical storage surface (6) for weft thread windings, a reeling element(2) that is rotatably driven relative to the storage member (K) about an axis of the storage member, and a stop mechanism (S) for measuring the length of the weft thread. The stop mechanism is provided with at least one stop pin (3). At least one extension part (V) which protrudes past the front end (5) in the draw-off direction (W) and is asymmetric relative to the axis (X) is disposed on the storage member (K). Said extension part (V) forms an at least linear winding support (A) which lengthens the storage surface (6) of the storage member in the draw-off direction (W). In addition, an opposite surface (16) that tapers in the draw-off direction (W) and protrudes past the front end (5) is provided at least approximately diametric to the support (A).

Description

technical field [0001] The invention relates to a yarn measuring feeding device (yarn measuring feeding device). Background technique [0002] Yarn measuring and feeding devices are used on jet looms, especially due to air-jet looms, for the purpose of: extracting weft material from a yarn store; storing windings intermediately on a storage body. ), in which the windings are in contact with each other or separated from each other; the intermediately stored yarn winding (yarn winding) is transferred in the direction towards the front end of the storage body; during each insertion operation and picking (pcik) only releasing a certain amount of winding measured by the unwinding brake; and finally terminating the picking, for example by the brake. [0003] Furthermore, International Publication No. WO-A-02 / 33157 discloses a yarn length measuring and feeding device equipped with a very small diameter yarn storage body and a braking device having a brake pin, which respectively ...
