Bending head attachment

摘要

A bending head for bending the peripheral edge of a sheet of material, the bending head being usable with a power source. The bending head includes an anvil member, the anvil member defining a substantially elongated anvil surface. A hammer member is movable relatively to the anvil member substantially perpendicularly to the anvil surface. An actuator is provided for receiving power from the power source, the actuator being operatively coupled to the hammer member for moving the hammer member relatively to the anvil member when the power source powers the actuator. The hammer member defines a hammer surface, the hammer surface being substantially elongated, the hammer surface substantially opposing the anvil surface so as to define a gap therebetween. The gap defines an entry point and a substantially longitudinally opposed exit point. The sheet of material is movable along the gap between the entry and exit points. The entry and exit points define respectively an entry transversal cross-sectional configuration and an exit transversal cross-sectional configuration. The entry and exit transversal cross-sectional configurations differ from each other. The gap has a transversal cross-sectional configuration that longitudinally transitions substantially smoothly between the entry and exit transversal cross-sectional configurations.
