ABSTRACT:
A textile yarn processing machine, such as a two-for-one twister and the like, having spindle assemblies for the processing of yarn and each including a carrier mechanism for carrying a pacakge of yarn to be withdrawn and processed and defining a passageway therethrough for yarn withdrawn from the package and an enlarged cavity forming a part of the passageway, includes the combination therewith of an improved, self-threading, yarn brake mechanism positioned in the cavity, as follows. A stationary braking member forms an inclined braking surface generally around the passageway at the entrance to the cavity and a movable braking plate cooperates therewith and generally covers the passageway at the entrance to the cavity and is adjustably biased toward the inclined braking surface for applying a desired tension to the yarn passing therebetween. A yarn bypass channel leads from the passageway at the entrace to the cavity laterally alongside the stationary braking surface for receiving the yarn and eliminating passage of the yarn between the braking surface and braking plate during threading of the yarn through the passageway for start-up of the spindle assembly. An obliquely extending deflection surface extends between the bypass channel and the inclined braking surface for deflecting the yarn from the bypass channel into position between the braking surface and the braking plate after threading of the yarn for start-up of the spindle assembly.
