A machine for driving and variable length cutting of the paper used in the armature of an electric motor rotor. The machine comprises a feed distance covered by the paper between shaping rollers, over which a pressure wheel is located which pushes the paper against a ledge and then slips. A paper cutting blade is inserted between the wheel and the ledge. Transfer devices located between the blade and the ledge transfer the cut paper to a bending fixture, which gives the paper the shape of the rotor slot. The paper is pushed into the rotor slot by inserting devices. The rotor is moved from the conveyor on which it is supplied to a suitable position to receive the paper. Locking elements connected to the ledge vary the length of the cut paper with respect to the height of the rotor slots where the paper is inserted.
A machine for driving and variable length cutting of a paper web for use in the armature of an electric motor rotor comprising:
The machine of claim 9 wherein said means for positioning said rotor comprises thrust blocks which pinch the rotor adjacent the ends of the slot, at least one such block being movable and connected to an actuator cylinder which positions said ledge, with respect to said cutting means, at a distance substantially equal to the distance between said thrust blocks.
A method for driving and variable length cutting of a paper web for use in the armature of an electric motor rotor comprising the steps of:
