Abstract

Method and apparatus for texturing thermoplastic threads. In starting the operation of the texturing device, one or several non-textured yarns can be drawn in more easily and more reliably via a drawing-in yarn guide which guides the at least one yarn for the purpose of drawing same into the feed channels of the texturizing nozzle and into the plug channels of the plug feed roller essentially parallel to these channels and at a predetermined distance from each other.
