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

A yarn length measuring and feeding device (F) according to the present invention comprises a fixed yarn storage body (K), a winding element (2) and a brake device (S). The yarn storage body (K) defines a substantially cylindrical storage surface (6) for weft yarn winding, said winding element (2) being rotatable relative to the storage body (K) along the axis (X) of the storage body (K) Ground drive, said braking device (S) is used to measure the length of yarn. The brake device (S) is provided with at least one brake pin (3). At least one extension (V) is provided on the yarn storage body (K), which protrudes from the front end (5) of the yarn storage body (K) in the unwinding direction (W) and is relatively Axis (X) is asymmetrical. The extension (V) forms an at least linear winding support (A) which continues the yarn storage surface (6) of the yarn storage body in the unwinding direction (W). Furthermore, at least approximately diametrically opposite to the winding support (A) there is provided a counter surface (16) which tapers in the unwinding direction (W) and protrudes beyond the front end (5 ).

Description

technical field [0001] The invention relates to a yarn measuring feeding device according to the preamble of claim 1 . 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 respect...
