    Abstract: AN AUTOMATIC SPINNING AND WINDING SYSTEM FOR HANDLING DIFFERENT TYPES OF BOBBINS AND INCLUDING A SELF-TENDING SPINNING SYSTEM FOR FILLING EMPTY BOBBINS WITH YARN, AND A SELF-TENDING WINDING SYSTEM FOR WINDING THE YARN FROM THE FILLED BOBBINS ONTO YARN PACKAGES. THE FILLED BOBBINS FROM THE SPINNING SYSTEM ARE STORED AND ARE AUTOMATICALLY SEPARATED INTO SUBSTANTIALLY EQUAL BATCHES WHICH ARE DELIVERED TO THE WINDING SYSTEM RESPONSIVE TO DEMAND OF THE WINDING SYSTEM FOR FILLED BOBBINS. EMPTY BOBBINS FROM THE WINDING SYSTEM ARE STRIPPED OF RESIDUAL YARN, AND ARE AUTOMATICALLY RETURNED TO THE SPINNING SYSTEM RESPONSIVE TO DEMAND OF THE SPINNING SYSTEM FOR BOBBINS. THE SPINNING AND WINDING SYSTEM MAY CONCURRENTLY HANDLE AND KEEP SEPARATE DIFFERENT TYPES OF BOBBINS.

    Abstract: Apparatus for winding a strand about a core. A pair of spaced rotatable elements are provided on which sufficient strand is wound to completely wind the core. Mechanism is provided for driving the rotatable elements to deliver the strand to be wound on a suitably supported core. Means is provided for sequentially and automatically picking off the wraps of strand wound off the rotatable elements, each picking off step being accomplished only after the prior strand wrap has been substantially wound onto the core.

    Abstract: An improved aspirator-shear unit for rapidly moving strand of yarn in which an aspirator nozzle is arranged with its axis in closely proximate more or less parallel relation to the yarn path, a fixed shear blade is situated laterally between the nozzle opening and the yarn, and a movable snubnosed shear blade is projected from an inoperative position on the opposite side of the yarn path from the aspirator nozzle and fixed blade across the yarn path into shearing relating with said fixed blade and finally to a deflecting position with its leading edge generally aligned with the nozzle opening. Preferably the aspirator nozzle axis is inclined at a small angle with respect to the yarn path to reduce the clearance from the yarn path required to physically accommodate the nozzle.

    Abstract: Yarn-treating apparatus including a rotatable applicator roll for treating an advancing strand of yarn and is movable between a retracted, operative position in which the roll is coupled to a drive mechanism and an extended, servicing position in which the roll is uncoupled from the drive mechanism. A supply trough provides treating material for the applicator roll and is adjustable for varying the depth of the treating material in the trough.
