Problems solved by technology

However, this can adversely affect the concentricity of the shaft
While this effect has hardly any negative consequences for yarns with sufficient elasticity, for yarns that lack elasticity, concentricity defects can lead to periodic oscillations in yarn tension, adversely affecting the quality of woven items

Embodiment Construction

[0035] figure 1 Shown is a yarn feeder 1 used as a yarn unwinding device delivering elastic or non-elastic yarn to a textile machine, such as a weaving machine, weaving loom, flat weaving machine, circular weaving machine or the like. It can be used to convey elastic or non-elastic yarns. For example, it is fixed to the ring holder 2 (called mechanical ring) of the circular knitting machine. Further, a cable 3 is disposed on the annular retainer with a rectangular cross section, which may include an off conductor, a signal carrying conductor, a control conductor, a ground conductor, and the like.

[0036] A fixing clip 4 provided on the yarn feeder 1 straddles the holder 2 and the cable 3 and serves to securely support the yarn feeder 1 on the holder 2 . A double shell plastic housing 5 with an upper housing part 6 and a lower housing part 7 extends away from the retaining clip 4 . Thus, the housing 5 is divided horizontally by the junction 8 and encloses an inner space. A...

Abstract

Disclosed is an improved yarn backing-off device. A yarn feeder (1) comprises a flexible cover (16), single rotary shafts (12 and 13), a casing and / or an electric drive motor (50), wherein the single rotary shafts are used for supporting a yarn spindle, and the casing and the electric drive motor are horizontally separated from each other. The yarn feeder is simple and reliable in manufacture and convenient in operation.

Description

[0001] This application is a branch of a patent application whose international filing date is May 17, 2006, titled "improved yarn unwinding device", and whose national application number is 200680054625.X (international application number is PCT / EP 2006 / 004662). case application. technical field [0002] The present invention relates to a yarn unwinding device, in particular for feeding elastic yarn to a yarn using machine, such as a weaving machine. Background technique [0003] For this purpose, suitable yarn delivery devices generally have two drive shafts arranged parallel to one another, on which at least one yarn spool is supported. The shaft is held in a carrier and driven by a gear. The gear input is built through a pulley, to which rotation is introduced through a drive belt provided on the weaving machine. Such prior art is disclosed, for example, in Taiwan Patent Application No. 82212959 (TWGM90131). [0004] A large number of yarn delivery devices are require...
