Abstract (en)
[origin: WO2018218270A2] The invention relates to an extrusion machine (1) comprising a main frame (5), a friction wheel (4), a tool-holding device (6), a locking device (11) and a tool unit (12) supported on the tool-holding device (6). A protection unit (28) with at least one first nozzle (32) and at least one second nozzle (33) are also provided. The nozzles (32, 33) are designed to dispense a gas which is free of gaseous oxygen. The first nozzle (32) is directed to a peripheral portion (29) of the friction wheel (4). The second nozzle (33) is mounted below a stripping area (30) of the tool unit (12). The invention also relates to an extrusion machine (1) having a sensor unit (25) between the tool holding device (6) and the tool unit (12) and to a method for controlling the distance between two tool components of the extrusion machine (1). The invention further relates to different extrusion machines (1) and to methods for changing friction wheels.
