ABSTRACT:
Method and apparatus to produce a plied, air textured continuous filament yarn by severing the supply yarn upon the detection of a drop in tension. When the tension in the yarn being processed drops, the position of the running yarn will be detected by a photocell unit which will actuate a cutter upon such detection to sever the yarns being supplied to the air texturing machine. The method and apparatus provide that the drop in tension has to occur for a predetermined length of time or occur a multiplicity of times before the cutter is actuated.
