Abstract
An extrusion machine includes a main frame, a friction wheel, a tool holding device, a locking device and a tool unit supported on the tool holding device. Furthermore, a shielding unit with at least one first nozzle and at least one second nozzle is provided, wherein the nozzles are formed to emit a gas which is free of gaseous oxygen. The first nozzle is directed at a peripheral portion of the friction wheel. The second nozzle is arranged below a stripping area of the tool unit. Further, an extrusion machine has a sensor unit between the tool holding device and the tool unit and a method controls distance between two tool components of the extrusion machine. Furthermore, different extrusion machines as well as methods for changing friction wheels are provided.
