Embodiment Construction

[0032] Hereinafter, a weft feeding device for a loom will be described. In the drawings, the same reference numbers refer to the same or corresponding elements throughout the several views. It should be appreciated that these figures are for illustration only and do not limit the scope of the present invention in any way. Furthermore, features from the different embodiments described may be combined to meet specific implementation needs.

[0033] For many types of yarn, twist is not allowed in the finished fabric. For such a yarn, the yarn feeding cannot twist the yarn, and the yarn is fed with zero twist, which can be called a zero twist yarn feeding device.

[0034] exist figure 1In the weft thread feeding device 12 is shown, which comprises a combination of a motor-driven spool 13 and a motor-driven coil buffer device 16 . The device 12 can be used to feed the yarn with zero twist. In the device 12 the weft thread 40 is unwound tangentially from the motor-driven spool ...

Abstract

Described are, among other things,methods and devices for providing a learning procedure in a yarn feeding arrangement (12). The learning procedure aims at providing control data to the controller (32) about system components and behavior of system components of the yarn feeding arrangement beforehand, such that the controller has knowledge of the system components before the weaving machine (10) is started to operate at full operational speed.

Description

technical field [0001] The present disclosure relates to a yarn feeding device. In particular, the present disclosure relates to a yarn feeding device suitable for a device comprising a motor-driven spool of a loom that can typically be used to weave flat or ribbon yarns, in flat or ribbon In the shape of the yarn, the weft yarn should be presented to the loom without twisting. Background technique [0002] The general trend in weaving is the ever-increasing speed of looms. Another trend is to increase the use of flat or ribbon-shaped forming yarns, which should be inserted without any twisting. Examples of such yarns are polypropylene tapes, carbon fiber tapes, aramid and glass fiber tapes. Currently, the speed at which rapier looms can weave flat or ribbon yarn without twisting is limited by the low capacity of the zero-twist yarn feeding devices that exist today. [0003] Existing systems for feeding yarn without twist (zero twist) typically have an unwinding motor co...
