    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 device for automatically doffing bobbins which are positioned between holding centers on support arms of a winding machine. The device is on a mobile carriage which patrols along the machine face and comprises an articulated chute shaped member for the guided discharge of the full bobbin from the winding machine, a presentation member to introduce new tubes, a gripper-type manipulation member which withdraws a new tube from the presentation member of the device and positions it between the holding centers on the bobbin support arm, a yarn positioning member which withdraws the yarn from the full bobbin and disposes it on the new tube, and a sliding belt which rotates the new tube to connect the yarn thereto.

    摘要: Equipment and process to supply winding tubes to individual reeling stations of a textile machine, and to carry out the subsequent insertion of a new winding tube between the bobbin holder arms of a collection station. The equipment comprises an accumulator device to position a number of reserve winding tubes in a spaced and aligned condition enabling transfer of an individual winding device axially to a collecting user device; a belt or cable transfer device for transferring the winding tube in axial position, to a winding station upon request by the winding station, or on a time preceding request; and a device for intercepting, collecting and inserting a new winding tube between the bobbin holder arms of the winding station.

    摘要: A device is disclosed, which is useful for subdividing and diluting an accumulated amount of pirns in bulk, which comprises a chute positioned between a pirn container, and a conveyor belt. The conveyor belt is prearranged to transfer and meter a limited number of pirns. Along the chute, at least one barrier wall is provided, which can move along a vertical, or substantially vertical, direction, and is driven by a drive source, whose enabling is commanded by a level sensor located downstream the same barrier wall. A plurality of movable barrier walls, following each other, transversely prearranged along the chute relatively to the pirn falling motion, can be used. Each barrier wall is driven by a drive source, whose enabling is commanded by a level sensor located downstream of the barrier wall.

    摘要: A device and a process for the regulation of the drive means which drive the various operating steps of the individual collection station of a winding machine, e.g., an automatic coner machine, wherein each collection station is equipped with a drive source.More particularly, said device comprises:a three-phase motor driving the drive roll by means of a positive transmission, such as a toothed belt;a variable-frequency inverter, which feeds and pilots the drive source, in conformity with the signals coming from a central control unit, which in its turn processes the working parameters coming from the winding station, together with the monitored data coming, in feedback, from the speed monitoring probe-wheel;a speed monitoring probe-wheel keyed on the drive shaft, capable of measuring the speed and the length of the thread being collected, according to preestablished sequences and operating cycles;a fully-reversible power circuit capable of making electric power flow both from the power supply distribution system to the drive source, and from this latter to the other drive sources of the operating front; or towards the same power supply distribution system.

    摘要: An apparatus and method for anchoring thread to the surface of a bobbin, the apparatus including a movable arm for grasping the bobbin and a lever attached to the movable arm, the lever having two members for engaging the surface of the bobbin with one of the members being a roller. The movable arm places the bobbin in a mandrel, and a second movable arm moves the thread between the roller and the surface of the bobbin. The roller is then brought into contact with the surface of the bobbin and the mandrel is rotated to thereby wind the thread onto the bobbin. The second movable arm includes a cutting blade for cutting the thread, and a hook and movable lever for moving the thread into position.
