    摘要： A device for sequentially loading tubes in a spinning machine wherein the tubes are fed by a tube orientating device. The device disclosed includes a duct for guiding the fall of the tubes and provided at its lower end with a shutter which loads one tube at a time onto the pegs of the spinning machine doffing belt by withdrawing it from a stack of tubes accumulated within the duct to form a buffer stock.

    摘要： This invention relates to a device for preventing yarn loop formation and for saving the suctioning yarn on winding units. This device keeps the yarn under tension during the knotting and cone doffing steps. The device has a movable bar which is positioned adjacent to the upper end of a pirn during the unwinding process and which is shifted by an actuator to contact the pirn before the yarn is stopped. This is accomplished by keeping the yarn under tension from the pirn cone to a yarn-tensioning disc at the beginning ot the knotting and doffing cycles to prevent loops from forming. Additionally, this device limits the yarn consumption of the knotting cycle. By frictionally clamping the free end of the yarn with an anti-loop device, yarn is suctioned by a free yarn end feed nozzle in a shortened length thus limiting the amount of yarn removed and lost during a knotting cycle.

    摘要： A splicer device for making a splice between two yarns by the mechanical removal and recomposition of twists having rings to untwist and retwist yarn, grippers to pluck and/or tear excessive yarn tail ends and form small retaining yarn tails, and any of an adjustable cam to separately condition untwisting and retwisting, a spacer to keep the surfaces working on the yarn at least for a moment a distance apart, movable portions on the grippers that move in opposite directions, and a tensioner to permit drawing action.

    摘要： Improvements to procedures for the splicing of yarns (20-21), whether textile or not, the splice being obtained by coupling two single untwisted yarns (20-21) and re-imparting the twists thereafter, in which improvements a part of the single yarns is untwisted until twists of a sign opposite to the original sign have been imparted, and such part is then coupled and small tails (220-221) are obtained, and the coupled segment is then retwisted by imparting a desired twist, such small tails (220-221) being obtained after a substantial parallelization of the fibres to be plucked and/or torn (42) and after a successive plucking and/or tearing action (40) along the axis of the yarns, the tapering (320-321) of such tails (220-221) reaching the neighborhood of the periphery of the retwisting rings (28), the resulting tails (220-221) being controlled and positioned alongside the yarns (21-20) before the beginning of such action to impart such desired retwisting, at least part of the segment of yarn being untwisted undergoing a drawing action at least during the untwisting step and at least at about the transient stage of conversion from one type of twist to the other (from "Z" to "S" or from "S" to "Z").

    摘要： This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part then being coupled and reduced tails (220-221) of yarns being obtained, the coupled tract then being retwisted until a required twist has been imparted, the improvements envisaging that the reduced tails (220-221) are obtained after the fibers to be plucked and/or torn (42) have been made substantially parallel and after a substantially axial plucking and/or tearing action has been applied to such fibers (42), and that the taper (320-321) of the remaining reduced tails (220-221) reaches the neighborhood of the periphery of retwister rings (28), the resulting remaining tails (220-221) being controlled and positioned beside the yarns (20-21) before the action to impart the required retwisting is begun.
