Abstract (en)
[origin: WO2009033300A1] In order to improve the quality of the cutting edge, particularly when the fabric thickness is changing, and to simplify the operation for the user, particularly when switching jobs, of a device for thermally cutting a running textile web made of meltable material, it is proposed to determine the target cutting temperature based on textile parameters in a controller (9) for the electrically heated severing units (1) that are typically powered by a commercial power supply unit (7) and are used for cutting the textile web (2) and to transmit it to the severing units (1) by means of a transmission device via contact rails (4). Each severing unit (1) has a dedicated temperature control device, by means of which the temperature can be controlled at the severing point in accordance with the specified target value, and a cutting wire (3) with a temperature-dependent electric resistor as the severing element. For this purpose, the current cutting temperature is determined and regulated based on the electric resistance of the cutting wire (3).
