Spinning and drawing device

Abstract

A spinning and drawing device that uniformly heats a plurality of filaments constituting one multifilament with a heating roller, and suppresses breakage of the filaments and generation of fluff. The spinning drawing device (2) is equipped with: a plurality of godet rolls (5a-6b) for drawing the multifilament (Y) as heating rolls; A widening wire guide (21) that widens the wire width (W) of a multifilament (Y) composed of a plurality of filaments (Y1); and restricts the wire width (W) of the multifilament (Y) to avoid The thread width restriction guide ( 23 ) is too wide for the thread width (W) of the multifilament (Y) widened by the widening thread guide ( 21 ).

Description

technical field [0001] The present invention relates to a spinning and drawing device for separately drawing a plurality of multifilaments spun from a spinning device. Background technique [0002] A spinning take-up machine including a spinning drawing device and a yarn winding device is known. The spinning drawing device is provided with a plurality of multifilaments for drawing multifilaments such as polyester fibers spun from the spinning device. The above-mentioned yarn winding device winds up the multifilament stretched by the spinning and drawing device to form a package. [0003] The spinning and drawing apparatus described in Patent Document 1 includes a first heating roll, a first separation roll forming a pair with the first heating roll, a second heating roll, and a second separation roll forming a pair with the second heating roll. After the multifilament is wound multiple times on the first heating roll and the first separation roll, it is wound multiple times...

AI Technical Summary

Problems solved by technology

When such a multifilament is heated and stretched on a heating roller, the filament breakage and fuzzing may occur due to contact with the heating roller, etc.
