Abstract

A device (1) comprising: a linear element (7) extending transversely with respect to the yarn path, and a slide (9) for releasing said yarn (F), said slide (9) There is a yarn sliding surface (9A) extending from said linear element (7) and inclined relative to said linear element (7). Said device comprises a vernier (11) capable of reciprocating movement parallel to said linear element (7) and configured to push said yarn along an inclined surface (9A) of said yarn releasing slide (9) line (F). The linear element (7) has a longitudinal groove (8) parallel to the longitudinal extension of the linear element (7). The sliding surface (9A) of said thread releasing slider (9) extends inside said longitudinal groove (8).

Description

technical field [0001] The invention relates to the field of yarn production. More particularly, embodiments described herein relate to improvements to apparatus for slub yarn production. Background technique [0002] In the textile industry, new types of yarns are constantly being developed in order to obtain specific technical and aesthetic effects. In textile technology, it is well known to produce so-called "slubb" fancy yarns, i.e. in which areas of accumulation (i.e. irregularities in thickness) are provided by suitable slubbing devices or units. yarn. Roving devices are disclosed, for example, in EP0299131, US6820405, US4368612. These devices are arranged along the yarn supply path and periodically grab the yarn in order to temporarily modify and lengthen its path. Once the yarn path has been lengthened, the yarn is released so that it forms a gather that creates a slub effect in the finished product. [0003] In order to have a correct yarn feed along the path t...
