Title:
CUTTING DEVICE AND CUTTING METHOD USING AN UNWINDING HEATING WIRE
Document Type and Number:
WIPO Patent Application WO/2023/057387
Kind Code:
A1
Abstract:
The invention proposes a cutting device for cutting a material, comprising a cutting wire (3) having two ends, each end being connected to a winding drum (1a, 1b), the wire (3) being tensioned, the wire (3) being conductive and having a voltage applied to it in order to heat. This cutting device is characterized in that the wire (3) is unwinding at the moment of cutting, with winding around a first drum (1a) taking place simultaneously to unwinding from a second drum (1b), the device having a dry cutting zone (2) in which is located an unwinding section of wire (3) able to cut the material coming into contact with it, the two drums (1a, 1b) being driven in rotation by two different motors (4).
