Apparatus for handling and texturizing yarn having enhanced false twister, electro-mechanical yarn detector, and yarn take-up distance extender and associated methods

摘要

An apparatus and methods for handling and texturing yarn are provided. The apparatus preferably includes a yarn supply positioned to supply a plurality of strands of yarn, a false twister positioned downstream from the yarn supply for imparting a false twist to the plurality of strands of yarn, a yarn undulation former positioned downstream from the false twister for forming undulations in each of the plurality of strands of yarn, and a conveyor positioned to receive the plurality of yarn strands having undulations formed therein and for conveying the undulated strands of yarn downstream. The apparatus also preferably includes a heat setting oven positioned downstream from the yarn undulation former and to receive the conveyed yarn when passing therethrough to impart heat to the plurality of strands of yarn having undulations therein, a yarn sensor system positioned downstream from the heat setting oven for sensing the presence and absence of yarn being conveyed on the conveyor, a yarn take-up distance extender positioned downstream from the yarn sensor system for extending the distance of travel of the plurality of strands of yarn prior to take-up, and a yarn take-up source positioned downstream from the yarn take-up distance extender for receiving and taking up the plurality of strands of yarn.
