  • 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.
