Problems solved by technology

And, since the rollers for preheating and the rollers for heat fixing with different set temperatures are aligned and densely arranged in the left-right direction, the surroundings of the rollers for preheating with low temperatures are heated by the heat generated by the rollers for heat fixing at high temperature. The temperature rises, so it is difficult to adjust the temperature of the roller for preheating

Abstract

An object is to provide a spun yarn drawing apparatus capable of efficient use of the heat generated by rollers. The spun yarn drawing apparatus 2 includes godet rollers 14 to 18. The godet rollers 14 to 18 include godet rollers 17 and 18 configured to thermally set a drawn yarn Y. Onto the godet rollers 14 to 18, the yarn Y is wound serially from the lowest roller to the highest roller, each at a winding angle of 360 degrees or lower. The godet rollers 17 and 18 are provided above the godet rollers 14 to 16 where the yarn Y before drawn passes through.

Description

technical field [0001] The present invention relates to a spinning and drawing device including a plurality of rollers for drawing and drawing a yarn spun from a spinning machine. Background technique [0002] A spinning take-up machine including a spinning drawing device, a yarn winding device, etc. is known. The spinning drawing device includes a plurality of rollers for drawing, drawing, and thermally fixing the yarn spun from the spinning machine. The above-mentioned yarn winding device winds the yarn stretched by the spinning and drawing device to form a package. [0003] In the spinning and drawing device described in Patent Document 1, two preheating rolls for preheating the yarn before drawing are arranged in a vertical direction, and are used to thermally fix the drawn yarn. The two rolls for heat fixing are arranged in line in the vertical direction, and the two rolls for preheating and the two rolls for heat fixing are arranged in line in the left and right direc...
