ABSTRACT:
A document trimming apparatus includes a document trimming mechanism and a document positioning mechanism. The document trimming mechanism includes a trimmer clamp for holding a document made up of a stack of sheets while being trimmed and a knife for trimming an edge of the stack of sheets. The document positioning mechanism includes a transport holder for securely holding the stack of sheets during transport and further includes a carrier movably supporting the transport holder for translational and rotational movement relative to the document trimming mechanism. The document positioning mechanism is adapted to position successive edges of the stack of sheets proximate the knife for trimming. The document positioning mechanism includes a first actuator to control rotational movement, a second actuator to control translational movement, and a third actuator to control a side block for initial positioning of the stack on the document positioning mechanism. A controller is operably connected to the document trimming mechanism and the document positioning mechanism including the actuators to control the sequence of operations. The actuators include stepper motors to control angular rotation and the distance of translation.
