  • Patent number: 4628676
    Abstract: A double-lay stranding machine for laying a predetermined amount of wire or stranded material on a reel comprises a lifting table for transfering empty reels to a reel carrier and for removing the full reels therefrom, the lifting table being provided with a pair of rollers for enabling the unwinding of a predetermined length of wire or strand from a wound reel during the removal process. The portion of the strand extending between a removed reel and a laying roller is automatically cut and held by a gripping and severing device. Upon the loading of an empty reel into the carrier, the leading free end portion of the wire or strand is automatically clamped to the outside surface of a reel flange and brought over the rim of the flange prior to a winding operation.

  • Patent number: 4483490
    Abstract: A wire manipulator at an individual coil winder has an arm pivotably and slidably attached to a support column itself slidable along a path parallel to a wire segment extending from a winding station to a fully wound spool at a coil changing station upon termination of a winding operation. A clamping head at the free end of the manipulator arm is provided with a wire severing device in the form of a cutting edge, an electrical circuit or a small torch.

  • Patent number: 4292114
    Abstract: Method and apparatus for winding wire on a double flanged spool by means of a single spooler wherein the wire is automatically carried from a feed roller toward the spindle by grasping the free end of an endless wire, guiding the grasped end in an orbital path about a spindle, until a portion remote from the wire is grasped by another means adjacent to the spindle and wire is then caused to be cast from the other grasping means over the end flange of the spool and onto the spool itself. Thereafter the wire is wound about the spool after which, the wire is automatically grasped and cut from the spool by the orbital means so as to restart a new cycle of winding.

  • Patent number: 4098467
    Abstract: Filamentary material is continuously wound on a pair of rotating spools, provided with feed means for excursively drawing the material to the spools and a transfer device for changing the feed of the material from one spool to the other. The transfer device is moved from association with the spool around which the material is being first wound to the spool around which the material is to be next wound in advance of the actual changeover of feed of said material from one spool to the other.

  • Patent number: 4072038
    Abstract: At least two adjacently located wire drawing capstans are provided with an annular drawing ring and a wheel member within the drawing ring and connected to it. At least one has a planet member engaging the wheel member, and an annular sun member secured to a shaft. The planet member is connected to the wheel member of the next adjacent capstan to operatively interconnect the adjacent capstans, and permit the planet member to revolve about said sun member and rotate about the central axis.

  • Patent number: 3953998
    Abstract: A multi-stage wire drawing machine having at least one drum formed with a plurality of sheaves over which the wire is sequentially pulled. The sheaves are disposed about a hollow sleeve in which is rotatably mounted a shaft connected at one end to a drive and at its other end to the farthermost sheave. The sheaves are interconnected by suitable gearing with each other and with the sleeve. The gearing is so adjusted that the peripheral speed of the individual sheaves increases in the direction of the passage of the wire, corresponding to the differential necessary to obtain only the least possible extension of the wire.
