ABSTRACT:
A device is disclosed for producing surface channels of at least approximately rectangular cross-section in sheeting consisting of a soft material, in particular mineral-fiber insulating mats or sheeting consisting of a styrene polymer. The device makes use of a motor-operated cutting tool with an oscillating cutter. The cutter comprises sections which are bent off relative to each other and which are provided with a cutting edge, at least in part. The cutting edge extends over at least three of two sections which form together a U or L, respectively. The cutter is passed through the sheeting approximately along a straight line.
