  • Patent number: 5913956
    Abstract: A control apparatus and method for progressively fracturing a work piece from a material sheet in a mechanical press in which the separation distance between an upper die and a lower die is varied in discrete steps as an upper platen advances the upper die toward the lower die, each discrete step occurring within the thickness of the material being stamped. Varying the separation distance includes a motion opposite to the relative direction movement of the upper platen at one or more predetermined distances to create a controlled release of stored forces in the dies and press frame. A distance measuring transducer generates an output indicative of the position of the upper die in relation to the lower die.

  • Patent number: 5860345
    Abstract: A slitting line includes a slitter, an uncoiler, and a thread sled between the slitter and the uncoiler for peeling material off of a coil of strip material and guiding it into the slitting arbors. The thread sled is displaceable transversely with respect to the material pass line from an active position within the material pass line to an inactive position displaced from the material pass line. When the thread sled is displaced into the inactive position, a substitute pair of slitting arbors that have been retooled may be rotated in a generally horizontal plane into an active position in the material pass line to perform a slitting operation. This thread sled is then displaced back into its active position in the material pass line, where it unpeels material from a coil supported on the uncoiler and guides the leading edge of the material into the retooled slitting arbors.
