ABSTRACT:
Method and apparatus for separating a bundle of blank pieces from a stack of sheets. The apparatus has a frame and a subframe which pivots with respect to the frame. The frame and subframe each have a clamp for clamping the stack of sheets along a stack plane and the bundle portion to be separated from the stack along a separation plane that intersects the stack plane. The subframe pivots with respect to the frame, bending the stack to cause the bundle portion to be separated from the remainder of the stack in such a way that separation is initiated at one point along the stack rather than across the whole stack or across an entire sheet of the stack. The subframe pivots about an axis that is skewed with respect to at least one of the planes to produce the described effect. Pressure sensors are included to detect the pressure being applied to the stack of sheets to ensure that sufficient force is applied to hold the stack steady in tension during the pivotal motion of the subframe, and yet avoid damage to the stack by the clamps.
