Abstract
A trimming apparatus for metal strip has trimming heads on opposite sides of a turntable along each edge of the strip so that the trimming heads can be rotated into the trimming position or into the maintenance and blade-replacement positions. On each of the turntables as well a scrap-strip cutter is associated with the respective trimming head and the scrap-strip cutters are disposed diagonally opposite one another across the turntable and each trimming head and its scrap-strip cutter on one side of the turntable is connected to a clutch half on the opposite side of that turntable so that the scrap-strip cutter and the trimmer are driven by a common drive.
Claims9
An apparatus for trimming strip and cutting trimmed scrap comprising respective side trimmers flanking a path of strip to be trimmed, each of said trimmers having:
- a support shiftable transversely to said path;
- a respective turntable on each support rotatable about an axis perpendicular to a plane of said strip;
- respective diametrically opposite trimming heads on each turntable rotatable on said turntable about said axis between a trimming position wherein one of said heads is positioned to trim said strip while the other of said heads is located at a readiness position enabling blade maintenance, the trimming head on one side of said axis being aligned with the trimming head along and on an opposite side of said axis along a diameter of the respective turntable;
- and
- respective scrap-strip cutters spaced from the respective trimming heads in opposite directions, but on the same sides of the axis as the respective trimming heads and said scrap-strip cutters being further diagonally across from one another on the respective turntable so that the trimming heads and their respective scrap-strip cutters are located on opposite sides of a median plane through the respective turntable and are displaceable between said positions by rotation of the respective turntable through 180°, said scrap-strip cutters receiving trimming waste from the respective plane.
