A registration means is disclosed for the alignment of a piecing apparatus with yarn processing stations of a textile machine requiring yarn repair, comprising control cam means which controls the registration engagement of the piecing apparatus with the textile machine by the registration means through provision of a counterbias or holding function, a registration camming means for bringing the apparatus into registration with stations requiring yarn repair and maintaining it there by engagement with the machine in a camming action, and resilient biasing and joining means for joining the control means to the camming means and providing a bias to the camming means for its resilient engagement with the textile machine. Such engagement may be made with camming notches or slots in a guide rail of the machine in register with the stations, or any other suitable way such as with camming projections from the machine. In one embodiment, the camming means may be a cam follower lever arm with a roller for engagement with the machine, and in another a plunger rod for entry into registration slots in the machine, such as in a guide rail.
