Problems solved by technology

[0005] However, the structure of the plied yarn produced on this device is not uniform, which is caused by the different yarn tension of the single yarn drawn from the primary twisted yarn bobbin

Embodiment Construction

[0011] figure 2 The two-step process of forming the ply wire is schematically shown. In the first processing step A called primary twisting, first the yarn 32, 42, 52 drawn from the feeding bobbin 31, 41, 51 is twisted on a plurality of two-for-one twisting spindles 30, 40, 50, and each has The two-for-one twists 33, 43, 53 of the twist are introduced into the winding unit 60 through the pulling units 34, 44, 54 respectively. The winding unit 60 makes the two-for-one twists 33, 43, 53 gathered together and adjacently distributed on the primary twist bobbin (doubling bobbin) 55 (ie the primary twist bobbin 15 in step B). The primary twist bobbin 55 is preferably wound as a cross-wound bobbin and the winding unit 60 has a corresponding reciprocating device 61 .

[0012] In the second processing step B (final twisting step), the primary twisted yarn bobbin 15 and the two-for-one twists 33, 43, 53 paralleled thereon are transported to the two-for-one twisted spindle 70 that for...

Abstract

The invention relates to a method for producing ply yarn, firstly in a ply-twisting step a plurality of yarns (5) are twisted and combined into a ply-twisting bobbin (15) and then the ply-twisting bobbin (15) is twisted The yarns (5) are further processed into final twisted yarns on the wire spindles by plying them with each other. In order to be able to produce plied yarns with as homogeneous a structure as possible and at the highest possible feed speed, the invention proposes that the yarns (5) adjacent to one another on the primary twist bobbin (15) are first separated in order to form the finish twist And pass through the yarn brake (14) separately from each other, so that the feeding yarn tension of the yarn (5) matches each other, then the yarn (5) is introduced into the yarn feeding port of the twisting spindle through the ply yarn guide (8), In order to ply at the double twist point (9). The invention also relates to a textile machine for the production of a ply yarn consisting of a plurality of yarns paralleled on a primary twist bobbin.

Description

technical field [0001] The invention relates to a textile machine and a method for producing plied yarn according to the preamble of claim 2 or 1 . Background technique [0002] Three methods are known which involve one processing step, two processing steps or three processing steps in the manufacture of plied threads such as cord, sewing or pommon threads. For the method with only one processing step, the primary twist formed on several spindles is led directly to the twist spindle with an integrally formed winding unit and is plied into a final twist and wound into a final twist bobbin. The advantage is that only one textile machine is required to produce the plied yarn and a good twist quality can be obtained, while the disadvantage is that on the one hand the feed speed is low and on the other hand the size of the final twist bobbin is limited. With the known method having two processing steps, firstly in a first step a plurality of twisted yarns are assembled and doubl...
