A method and apparatus for die cutting at least one blank in a sheet and stripping waste material therefrom, characterized by forming a band of interconnected individual sheets by positioning the leading edge of the sheet in alignment with the trailing edge of the last sheet in the band, interconnecting the edges and then intermittently conveying the band of interconnected sheets through a platen press with a dwell for die cutting, followed by a dwell in a stripper station for removing waste and then separating the die cut sheet prior to transfer to a delivery station for subsequent handling. In the preferred embodiments, the separating of the sheets can be accomplished subsequent to the stripping of the waste material or during the stripping operation. To intermittently transport the sheet to the various stations, a drive roll is connected by a oneway clutch to an oscillating sector gear which is preferably disposed at the input side of the die cutting station and at the output side a tensioning device is utilized to maintain the sheet in tension during the dwell period in which a die cutting operation is performed. |
