Abstract
A cutting apparatus for cutting the unwound end of a coiled strip having a wedge for lifting the coil end away from the coil as the coil is rotated in a direction of unwinding, a strip guide surface for supporting the lifted coil end and a rotary cutting tool movable along a feed guide across the unwound strip thereby severing the unwound strip from the coil without the need to plastically deform the coil by bending. The feed guide may be on a support member, and the support member and the wedge are pivotable independently about an axis parallel to the axis of the coil.
Claims9
Apparatus for severing the end of metal strip wound in a coil comprising a base member, means on said base member for rotatably supporting said coil of metal strip, a wedge mounted in an operative position with respect to said coil for lifting the coil end away from but closely adjacent the coil as the coil is rotated in a direction of unwinding, a strip guide surface on said wedge for supporting the lifted coil end closely adjacent the coil, a rotary cutting tool, a cutting tool feed guide mounted in an operative position with respect to said coil and cooperatively engaging said rotary cutting tool so that said cutting tool is movable in a direction substantially transverse to the unwound strip supported on the strip guide surface to thereby sever the unwound strip from the coil, a drive means for moving said rotary cutting tool along said feed guide and a drive means for rotating said cutting tool.
