ABSTRACT:
A severing apparatus for sheet-laminating machines for separating sheets, transported as single sheets and coated with a continuous film layer, with severing of the overhanging film layer in the edge region of the overlapping area by means of a moving knife, wherein on a rotary table taking hold of the sheet line from below, at least one and preferably several knives, distributed at equal intervals over the periphery, are pivotably mounted with an essentially radial cutting edge, which, by means of a cam control, on passing over the edge of the sheet line, can be lowered from a raised position into an operating position gliding on the sheet line and can be raised again running up from the sheet line, and wherein the circumferential speed of the knife section cutting into the film layer is appreciably greater than the conveying speed of the sheet line.
