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.

Strand winding apparatus

Package winding of textile strands uninterrupted by transfer from a full to an empty package is accomplished by delaying lateral transfer of the winding strand from a full to an empty package and by picking up a resulting transfer tail of the laterally transferring strand adjacent the end of the empty package. The transfer delay step utilizes a bistable inertial device located to intercept the laterally transferring strand and to be repositioned thereby and to release the strand after momentary inertia-induced delay during which the strand begins to wind onto the empty package. The pickup step utilizes rotary devices located at the spaced adjacent ends of spindles for the respective packages, such device on the spindle of the package to which the strand is transferring being adapted to engage and grip it. The strand is broken or otherwise severed between the pickup device and the full package, thereby enabling the strand to be traversed onto the empty package.

Strand winding

Conveyor apparatus for temporary holdup of textile strands, especially crimped strands for setting. Screenlike conveyor belts receive the strand between downwardly converging flights and discharge the strand from between upwardly diverging flights. The conveyor apparatus is housed in a heated steam-fed enclosure.
