Rotary yarn feeding device having passage-of-reeling-thread control guide, and sample warping machine

Abstract

Disclosed is a rotary yarn feeding device which has a yarn path controlling yarn guide and is used for twisting the thread to a warping machine roller of a sample warping machine. The yarn feeding device comprises a number of bobbins; a number of fixed thread yarn guide for twist the thread from a bobbin around the warping machine roller; and a moving yarn path controlling yarn guide arranged adjacent to the fixed warping machine yarn guide so that it can be shifted to control the threads which are unreeled from the bobbin and pass through the thread yarn guide to go into the channel of the winding thread winded on the warping machine roller and the suspending thread not winded on the warping machine roller.

Description

technical field [0001] The present invention relates to a new type of rotary yarn feeder with yarn passage control yarn guides for sampling warpers and a novel sampling warper with yarn passage control yarn guides for sampling warpers, They can realize pattern warping by simultaneously realizing warping of a plurality of yarns according to preset pattern data (yarn distribution order, color yarn distribution order). Background technique [0002] In Japanese Patent No. 3454805, German Patent No. 10061490, Japanese Patent Application Publication No. 2004-346477 and German Patent No. 10323383, a rotary yarn feeder and a sampling warping machine commonly used are disclosed, wherein The yarn guide is replaced in such a way that it is possible to sort the yarns into those that wrap around the warping cylinder and those that do not wrap around the warping cylinder. [0003] The applicant has proposed a sample warper with a yarn recovery mechanism, and this application has been suc...

AI Technical Summary

Problems solved by technology

[0009] As mentioned above, in the prior art, when the yarn guide is displaced from the winding suspending position to the winding position, the yarn is immediately drawn with a length approximately 1.5 times the displacement distance of the yarn guide. Unwind, which can cause yarn breakage

Moreover, when the yarn guide is shifted from the winding position to the winding suspension position, the yarn is loosened immediately with a length approximately 1.5 times the displacement distance of the yarn guide, which causes the yarn to loosen
