Abstract
Fusion cutting of thermoplastic sheets and textile webs involving bonding of the cut edges is achieved with excellent quality without the accumulation of dirt particles, if the material to be cut is subjected, in the area of the intended cut, to pre-stamping and cutting in immediate succession, under heat and with precise guidance of the separator device in relation to the pre-stamping device, said pre-stamping and cutting being effected in such a way that the plane of symmetry through the pre-stamping device, which plane of symmetry extends perpendicularly to and in the same direction as the material web, is identical to the plane of symmetry extending through the separator device.
