Title:
METHOD AND APPARATUS FOR PRODUCING UNTWISTED YARN FROM AT LEAST TWO FILAMENT BUNDLES POSITIONED CONSTANTLY RELATIVE TO ONE ANOTHER
Document Type and Number:
Japanese Patent JPH03193907
Kind Code:
A
Abstract:

PURPOSE: To produce an untwisted yarn capable of imparting special color effects to the final product by making respective filament bundles maintain mutual positions with spinnerets through the whole process of spinning, drawing and crimping.

CONSTITUTION: Filament bundles (a), (b) and (c) are, for example, spun through the respectively corresponding spinnerets arranged on a line in a paper plane, passed through an oiling head 21 parallel to the spinneret line, separating pins 23a, 23b and 23c perpendicular to the spinneret line, formed into a filament bundle group and further formed into a strip material. The resultant material is separately run through a separating roll 24, reformed into a filament bundle, passed through an oiling device 25, a pair of centering pins 27, a separating pin 28, a cutter 29 and a separating pin 30, subjected to a spinning process 11, then passed from a yarn guide 13 and treated with a drawing step 12 and a crimping step 13 to produce the objective untwisted yarn having the individual filament bundles oriented in maintained mutual positions.
