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 according to a preliminarily designed design pattern, producing a thread supplying package 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, and organizing a weft to the warp supplied from the warp beam for forming different design patterns of a plurality of kinds continuously each with a warp thread jointing area disposed therebetween in the weaving direction.

Weaving system for woven fabrics of various kinds in small lots

The present invention provides a hairiness suppressing device for an automatic winder that can perfectly balloon a spun yarn using a whirling current in a yarn passage. In a hairiness suppressing device (,) comprising a yarn inserting opening (,) that extends and opens in an axial direction of a yarn passage (,) in which a whirling current acts on a spun yarn, a wedge-shaped cover member (,) is provided that can open and close the yarn inserting opening (,). When a swiveling body (,) is swivellably moved to open the cover member (,), the yarn can be introduced into the yarn passage (,) through the yarn inserting opening (,). When the swiveling body (,) is swivellably moved to close the cover member (,), the whirling current in the yarn passage (,) is prevented from leaking from a side of the yarn passage (,).

Hairiness suppressing device for automatic winder

The present invention relates to a dyed-yarn winding method wherein specified length control operates to wind a specified length of a dyed-yarn y without dyeing specks to a winding package Pw, and then cuts the dyed-yarn to remove a dyed-yarn having dyeing specks and remaining an a dyed-yarn supply package Ps. Since the specified length control prevents that part of a dyed-yarn that has dyeing specks from being wound to a winding package, an operation for removing such a part from the winding package can be omitted.

Dyed-yarn winding method

A bobbin carrying tray having an air passage extending through a peg adapted for insertion in a bobbin, and through a base underlying it. Some linear members are provided at the midway portion of the air passage to prevent the passing of yarn which is suspended in a bobbin by the air drawn through the air passage.

Bobbin carrying tray

A system comprising spinning-bobbin feeding lines and empty-bobbin feeding lines connecting spinning frames with winders is provided, in which the feeding lines are provided in a feeding groove provided below a floor surface on which the machine bases are disposed, and the spinning-bobbin feeding lines are separate from the empty-bobbin feeding lines only in the vertical direction.

Bobbin feeding system

A yarn splicing device for spun yarns to each other wherein end sections of two yarns are untwisted and placed in overlapping relationship one on the other and thus overlapping portions of the yarns are acted by fluid to intended splicing of the yarns. An untwisting nozzle of the yarn splicing device comprises a fluid injecting hole formed to open to an inner circumferential face of a nozzle pipe and an intercepting plate disposed on a portion of the inner circumferential face of the nozzle.

Yarn splicing device for spun yarns

A pneumatic yarn splicing apparatus having a splicing member arranged in the central portion thereof. The splicing member comprises a yarn splicing hole of a cylindrical shape extending through the body of the splicing member, a slit extending along the splicing hole and two nozzles opened to the splicing hole in confronting relation. The two nozzles are so constructed that there is a time lag between the initiation of jetting at a first nozzle and the initiation of jetting at a second nozzle.
