摘要:
A method for winding a sheet of aligned parallel yarns onto a beam is described. The aligned sheet of material is preshrunk using heated rollers (206,208,210) and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.

The present invention provides an arrangement that enables diverse patterns to be inexpensively made in a warping system 1 that winds a predetermined length of warps Y supplied from warping creels 10a, 10b to form a warping beam 11. A plurality of yarn switching mechanisms 3 are arranged in a yarn path formed between the warping creel 10a and the warping beam 11; each of the yarn switching mechanisms 3 includes a yarn selecting device 7 and a splicing device 8 that splices a selected warp. Package groups 4 each including a plurality of supplying packages 5 of different yarn colors or the like are set on the warping creel 10a in association with the respective yarn switching mechanisms 3. A warp group Y, Y, ... unwound from the package group 4 are supplied to the yarn selecting device 7 in the yarn switching mechanism 3. The yarn selecting device 7 selects and supplies at least one warp Y of the supplied warp group Y, Y, ... to the warping beam 11 side. All or selected ones of the yarn switching mechanisms 3, 3, ... are actuated to switch the warps Y within the winding length of the warping beam 11.

A method for sizing a polytetramethylene terephthalate fiber yarn, characterized as comprising controlling the stretch ratio S (%) between a squeezing roll and a drying cylinder to a range from -9 % to -3 %, or from -1 % to +4 %; and a beam of sized polytetramethylene terephthalate fiber yarns for weaving having a winding hardness of 65 to 90 degrees, which may be obtained by winding sized yarns prepared according to the above method round a beam with a tension of 0.09 to 0.22 cN/dtex. The beam for weaving is improved in sticking property and exhibits good weaving characteristics.

The present invention provides a weaving system for woven fabrics of various kinds in small lots, capable of weaving woven fabrics of various kinds in small lots in a continuous operation by an existing weaving machine while preventing generation of waste to the minimum degree. A weaving system for woven fabrics of various kinds in small lots, comprises the steps of successively selecting a plurality of kinds of threads (Y A ,Y B ,...Y N ) according to a preliminarily designed design pattern, producing a thread supplying package (P A ,P B ,...P N ) for the warp by jointing per a predetermined thread supply amount, warping a plurality of the thread supplying packages for the warp so as to provide a warp beam (7), and organizing a weft to the warp supplied from the warp beam (7) for forming different design patterns of a plurality of kinds continuously each with a warp thread jointing area disposed therebetween in the weaving direction.

摘要:
Method for the preparation of a weaving warp or warp section (18) formed by monofilament thermoplastic synthetic yarns, characterized by the use of a spinning head (5) providing continuously the number of yarns required to form the warp, by the direct use of the bundle of so obtained yarns in the subsequent warping process and also by the use of a yarn accumulation and recovery device (12) in order to avoid the need for stopping the spinning process at a beam change.
