ABSTRACT:
An apparatus for trimming three-dimensional workpieces made, e.g., of plastic comprises a bottom platen for supporting the workpieces and a cutter, which is movable relative to the bottom platen along a line of cut. To permit an automatic trimming by means of an inserted-tooth cutter, the bottom platen extends across the line of cut to support also that portion of the workpiece which is to be trimmed off. The bottom platen has a top surface for supporting the workpiece and is formed with a groove extending along the line of cut.
