Embodiment Construction

[0047] Next, a spinning machine (spinning machine) according to an embodiment of the present invention will be described with reference to the drawings. In this specification, "upstream" and "downstream" refer to upstream and downstream in the traveling direction of a fiber bundle and a spun yarn during spinning.

[0048] The spinning machine includes a plurality of spinning units 2 arranged in parallel and a machine control device 5 that collectively manages the spinning units 2 . The machine controller 5 is provided with a setting unit 6 capable of setting spinning conditions (the count of the spinning yarn 10, the spinning speed, and the like). Each spinning unit 2 spins the fiber bundle 8 sent from the draft device 7 by the air spinning device 9 to generate a spun yarn 10 , and the winding unit 26 winds the spun yarn 10 to form a package 50 .

[0049] Such as figure 1 As shown, each spinning unit 2 includes a draft device 7, an air spinning device 9, a yarn accumulating ...

Abstract

The invention provides a spinning machine and a spinning method. The spinning machine includes a drafting device (7), an air-jet spinning device (9), and a yarn pooling roller (41). The drafting device (7) includes plural draft rollers, including a front roller (20), and drafts a fiber bundle (8). The air-jet spinning device (9) performs spinning to form a yarn (10) by twisting the fiber bundle (8) drafted by the drafting device (7). The yarn pooling roller (41) pools the yarn (10) formed by the air-jet spinning device (9) by winding the yarn (10) around a surface thereof. A peripheral speed of the front roller (20) during yarn discharge spinning and during regular spinning performed after yarn discharge spinning is different. A peripheral speed of the yarn pooling roller (41) during the yarn discharge spinning and during the regular spinning is different.

Description

technical field [0001] The present invention mainly relates to a spinning machine provided with an air spinning device for spinning out yarn, and accumulating the yarn generated by the air spinning device on a yarn accumulating roller. Background technique [0002] Conventionally, there is known an air-jet spinning device that performs yarn delivery spinning. Yarn-out spinning refers to a process of producing a yarn by performing spinning different from normal spinning at the start of spinning so that the reference yarn is not passed through the air-jet spinning device. [0003] Japanese Patent Laid-Open No. 2003-278035 (Patent Document 1) discloses a spinning machine that performs yarn discharge spinning. The textile machine includes a plurality of draft rollers (rear roller, third roller, second roller, and front roller in order from the upstream side) and a plurality of opposing rollers. Patent Document 1 describes a technique for increasing the success rate of the yarn...
