Embodiment Construction

[0024] exist Figures 1a to 1c An embodiment of the slub forming device 1 according to the invention and its arrangement in a plane perpendicular to the thread path of the yarn to be texturized is schematically shown in FIG. The figures here show the lateral deflection of a filament 2 of the yarn out of its yarn path in order to form slubs during the crimping of the yarn. The slub forming device 1 has a driver 4 mounted on a cable 6 or belt of a diverting element. The cable 6 or the belt is guided around two deflectors 8 designed as wheels similarly to the case of a belt drive. At least one of the wheels is driven by an electric motor (not shown in FIG. 1 ), so that the reciprocating element with the driver 4 runs in a driven cycle (circumvention) in the direction indicated by the arrow.

[0025] The driver 4 has a thread guide 9 by which the thread 2 can be moved linearly away from the thread path by gripping the thread 2 when the driver 4 circulates, that is to say the thre...

Abstract

Proposed is an apparatus (1) for producing fancy yarns in the course of texturing of yarn by producing slubs through brief yarn overfeeding, comprising a motor-driven dog (4) which is moveable linearly away from the thread course (35) and which has a thread guide (9) to produce a yarn underfeed by gripping one thread (2) of the yarn with the thread guide (9) and laterally deflecting the yarn from its thread course (35). Trigger means (10) are provided to release the thread (2) from the thread guide (9) at a deflection point positioned laterally from the course (35) of the thread (2) in order that the yarn overfeed may be produced by abrupt ending of the deflection of the yarn.

Description

technical field [0001] The present invention relates to a device (slub forming device) for manufacturing a design thread by generating slubs by utilizing a short-time yarn oversupply when crimping a yarn. Background technique [0002] In air-jet texturing, monofilament yarn passes through an air-jet texturing nozzle (air-jet texturing nozzle) in a fully stretched state (FDY, Fully Drawn Yarn) in most cases to obtain a certain bulkiness. At this point at least two yarns are connected to each other. The two yarns are so-called core yarns and at least one so-called fancy thread which is arranged around the core yarn by air-jet texturing. If the bulkiness changes in the yarn path, so-called fancy yarns are produced, otherwise, so-called crimped yarns are produced. The strength of the fancy yarn is determined by the core yarn. The tactile properties of the fancy yarn, such as its bulk, are determined by the fancy thread. The bulkiness of the fancy yarns is also determined by ...
