Abstract
PURPOSE:To groove a continuously running foamed plastic sheet with improved machining accuracy at a high speed, by forming at least two cut slit grooves on the surface of the sheet, and by stripping the cut parts with a heated jig. CONSTITUTION:A plurality of slit grooves 15 are cut at a uniform depth on the foamed plastic sheet 3 fed to the groove cutting part 12 by the rotary cutters 16 while holding the sheet 3 with the guide rolls 1 at the both ends 2 and 2. The sheet 3 is then fed to the grooving part 13 and held by the pressure rolls 18 and 18 at both faces, and the cut parts 19 of the sheet 3 are stripped while being molten by the parts 20a at the tips of the forks 20C heated with the heater 20b of the jig 20 to form the grooves 7 and 7.
