Abstract

Claims8
A film cutter comprising:
- a set of feeder means (7) for feeding a planar body comprising plural short plates partly overlapping, said planar body being covered by a transparent sheet (4),
- a knife (6) having a rectangular blade extending to a sharp cutting point, said knife (6) being placed at an angle to the top surface of the lower level of said planar body, said knife (6) being configured to be inserted in a thin slit (1d) made between the upper level and the lower level of said planar body, said knife (6) being traversed by a traverse means (8) to cut said transparent sheet (4) along a linear portion connecting said overlapped plural short plates, and
- means (9) for regulating said angle in response to the progress made by said feeder means (7).
