Abstract
Textile strands are transferred from a full package to an empty bobbin spaced endwise therefrom, by delaying traverse of the winding strand and by picking up the strand and forming a resulting transfer tail on the end of the empty bobbin. The pickup step utilizes rotary bristles located at the spaced adjacent ends of spindles for the respective packages. The transfer delay step may utilize a bistable inertial device positioned to intercept the transferring strand, and functioning to release the strand after a momentary delay, after which delay the strand is wound onto the empty bobbin to begin the formation of a package. The inertial device has adjustable ears and includes variable weights serving to vary the timing delay, whereby the length and position of the transfer tail may be controlled and adjusted. It also has a specially tapered structure so that even if transfer is attempted while the device is positioned out of phase, the yarn will nevertheless reposition the device in phase to actuate the delay function.
