Improvements in or relating to cutting wound coils

Perfectionnements à/en concernant la coupe de bobines enroulées


A wound coil (2) which is rotating about its axis is cut and severed against a support (4) by moving a rotatable cutting blade (6) incorporating an arcuate cutting edge towards the rotating coil and the support such that the cutting blade rotates about the axis of the arcuate cutting edge against the wound coil, becomes inserted between adjacent turns of the wound coil and cuts the wire forming the coil against the support. Once the coil has been cut, the cutting blade is moved away from the coil.
