Patent

CA 2359790

An inside perimeter hemming machine is disclosed having a base adapted to be supported by a ground surface. A nest adapted to support the part to be hemmed is vertically movably mounted relative to the base between predetermined vertical positions while at least one actuator vertically moves the nest relative to the base. A die assembly housing is mounted to the base, and this die assembly housing extends through the opening on the part to be hemmed. At least two die sets are horizontally slidably mounted to the housing so that the die sets are movable between an extended and a retracted position. In their extended position, the die sets overlay the part to be hemmed so that, upon vertical displacement of the nest, a prehem or hem is performed. Conversely, when the die sets are in their retracted position, the nest together with the part to be hemmed is freely vertically movable. A wedge drive member is utilized to simultaneously move the die sets between their extended and retracted positions.
