ABSTRACT:
A front feed system that includes powered rollers for feeding sheet metal into the front of a shear. In one embodiment, the system uses ball transfer apparatus for facilitating feeding the sheet metal at various angles to the shear blade as desired by the operator. The transfer apparatus may then be lowered to rest the oriented sheet metal on the rollers for delivery to the shear. In a second embodiment, a turntable is positioned proximate the shear to further facilitate final orientation of the sheet material to be sheared. In a third embodiment, the sheet metal is automatically forced against a squaring arm on the shear to assure cuts perpendicular to the edge of the sheet metal, whether the sheet is positioned on the ball transfer apparatus or on the rollers through inclination of portions of the conveyor and/or the ball transfer apparatus.
