Method and apparatus for cutting sheet metal wrappers or the like |
摘要 |
A method and apparatus for automatically cutting wrappers or the like from metal sheets. A metal sheet is conveyed in the x-direction to a cutting position wherein a pair of cutting blade (i.e., shears) assemblies cut edge portions from the metal sheet to form a cut wrapper or the like having longitudinal edges. The cutting assemblies are movable in the y-dimension-transverse to the x-direction-and are also angularly movable. From the cutting position the cut wrapper is continuously conveyed to a notching position wherein notching assemblies also movable in the y-dimension may form notches in the longitudinal edges of the cut wrapper. At a further point in the x-direction, an edge deforming position may be provided including edge deforming apparatus that also is movable in the y-dimension. Flexible elongated members or the like support the metal sheet spaced from its conveyor during conveying to prevent damage to the conveyor by the cutting or notching assemblies.
