ABSTRACT:
The apparatus for cutting semi-rigid sheets one by one, in particular corrugated cardboard sheets, comprises a cutting tool fixed on a tool-carrier plate, a backing cylinder, at least one independent motor having electronic servo-control and rotatable in either direction driving the tool-carrier plate in its reciprocating motion, and device for monitoring rotation of the backing cylinder and connected to a controlling electronic circuit provided with an input for receiving operating parameters including at least the length l of the cutting tool. The electronic circuit is programmed so that the amplitude of the reciprocating motion is a function of the parameter l and so that the linear speed of the tool-carrier plate is constantly equal to the peripheral linear speed of the backing cylinder so long as the cutting tool is in contact with said backing cylinder.
