Abstract (en)
[origin: EP0933171A2] A support frame carries adjustable tensioning and reciprocating mechanisms to oscillate the heated cutting wires axially by 5-15 mm at about 40 Hz during relative movement to the polystyrene blocks. Each wire has its own tension spring with a common eccentric driven rocker shaft running the length of the frame. A tilt mechanism can disengage the rocker drive using a hydraulic actuating cylinder.
