  • Patent number: 4890470
    Abstract: A loop transport system for baskets containing looped rod material to be drawn in a drawing machine is provided. Such system includes a conveyor arranged in a substantially closed loop. The conveyor supports and guides a plurality of baskets containing the material to be drawn sequentially to a feeder station, a payoff station, a delivery station and a basket removal station. In these different stations the functions to be performed therein are executed simultaneously or at least partially at the same time. To significantly improve the effectiveness of such a transport system and to reduce the drawing time, due to the inevitable tears in the looped rod material, the invention provides in the area between the payoff station and the delivery station a basket handling branch for the introduction and extraction of baskets containing the looped rod material to be drawn.

  • Patent number: 4754633
    Abstract: Wire drawing apparatus employs a wire take-up device, a rotatable pay-off device and, located therebetween, a rotating wire drawing die. Mounted on the pay-off device is a coil of material from which wire is drawn by the apparatus. This material may be in the form of rod, for example, and, for the sake of simplicity, will be referred to as such hereinafter. The axis of the pay-off device and rod coil thereon, the axis of the take-up device and the wire coil formed thereon and the axis of rotation of the rotating die all are parallel to each other and preferably, but not necessarily, coaxial. A differential speed compensating drive is connected to and drives the pay-off device in the same direction as the die to compensate for the elongation of the rod as it is drawn into wire. The rod is maintained and transferred in substantially the form of a coil between the pay-off device and the take-up device and passes through the die, which rotates in a plane between the pay-off and take-up devices.

  • Patent number: 4604883
    Abstract: A mass flow control system for a wire drawing machine wherein wire is drawn through a die by a rotating block driven by a variable speed motor. The thus drawn wire is accumulated as a plurality of windings on the block before being removed therefrom via a guide. The guide is arranged on a carrier ring which rotates independently of the block about the axis of block rotation when a difference exists between the rates at which wire is wound onto and removed from the block. The control system includes a motion detector for generating electrical signals representative of the direction and speed of rotation of the carrier ring. Controls associated with the drive motor and responsive to the aforesaid signals adjust the rotational speed of the block in order to reach a steady state condition where wire is being wound onto and removed from the block at the same rate, and the carrier ring remains motionless.
