ABSTRACT:
A cutting device for strip stock includes a stationary blade and a motor-driven, movable blade that continuously contacts against the stationary blade, constituting a point of support. Two other points of support for the movable blade are equally spaced from the cutting edge of the blade and from the sides of the blade. The other two supporting points also function as blade drive points for moving the blade in a reciprocating manner. The drive points are connected to an output shaft of the motor through a gear assembly. A pair of ball bearings on each side of the blade, which are laterally spaced from each other on each respective side of the blade, cooperate with the blade to achieve a very low friction for the device during operation.
