ABSTRACT:
A slitting machine for cutting rolled material is disclosed which is maintained in position through use of a support frame. A support cylinder is unmovably connected to the support frame at one end. An expansion rod is centered within the support cylinder with one end extending through the frame and affixed to a lever. A rigid sleeve, preferably having a slick surface, is over the support cylinder. A motor is incorporated with a receiving channel receive the support cylinder is attached to the support frame. A flexible expansion ring is placed in contact with the motor, to allow it to revolve with the motor. A bearing and washer, with diameters greater than than the base leg of the rigid sleeve are placed between the connector affixed to the expansion rod and the support cylinder. The lever is equipped with a gear which, when the lever is placed in a locked position, shortens the distance between the connector and the support frame. A cutting device is movable horizontally along a blade support rod. The cutting device has a handle which comprises a guidance bar and an activation bar which is approximately parallel to, and spaced from, the guidance bar.
