Method for manufacturing cross-wound bobbins and station for carrying out the method

Abstract

PROBLEM TO BE SOLVED: To enable production of a twill winding package formed in a manner of enabling the production of relatively short piece goods inexpensively.SOLUTION: A method of producing a twill winding package includes repeating following processes until the twill winding package is completed: supplying a work part computer (18) with data on package layers constituting a twill winding package to be produced, prior to starting a rewinding process for a twill winding package (6) constituted of a plurality of package layers (19a, 19b, 19c, 19d and the like), mounting storage bobbins (3, 3, 3and the like) each storing a thread material of a different kind on a rotary magazine (1), starting winding for a first package layer by the work part computer, watching a length of the thread being wound on the first package layer, stopping the rewinding process when a prescribed length of the thread is wound on the first package layer, and starting exchanging the first storage bobbin for a second storage bobbin storing a thread material for a second package layer by the rotation of the rotary magazine.

Description

technical field [0001] The invention relates to a method of manufacturing cross-wound bobbins and a station for carrying out the method. Background technique [0002] In the textile industry, especially in the field of outerwear, each colored loom goes through several selection phases every year, in which very short warp threads have to be warped, especially for the production of sample fabrics on the loom. In connection with this, it is usually necessary to warp warp threads which are only a few meters long. Subsequently, so-called short warp threads are woven on a loom to thereby produce sample fabrics or several shaped clothing pieces. [0003] To date there have been only two possible ways for colored looms to produce such short warp threads. A first possibility consists in warping the short ends on a section warping machine. For this purpose, several hundred small bobbins of different colors must first be wound, which must then be painstakingly inserted on a warping ...

AI Technical Summary

Problems solved by technology

The greater the deviation of the yarn lengths of these cross-wound packages, the greater the amount of residual yarn left on the cross-wound packages, which leads especially with high-value yarn materials to intolerable losses due to a significant amount of waste or result in laborious and time-consuming rewinding of remaining yarn
