Abstract
A textile yarn processing machine, such as a two-for-one twister, is provided with a pneumatically operated yarn threading mechanism for initially threading a yarn through a hollow spindle of the textile processing machine during a thread-up operation and an improved self-threading yarn brake mechanism for applying tension to the yarn as it passes through the hollow spindle during operation of the machine. The improved yarn brake mechanism is constructed to cooperate with the threading mechanism to facilitate automatic threading of the yarn through the hollow spindle and is characterized in that the compressed air which is supplied to the threading mechanism during the thread-up operation also operates to move the yarn brake mechanism from an engaged position to a released position to thus automatically provide a clear path for threading the yarn through the hollow spindle.
