ABSTRACT:
An overlap cam for use in a precision sheeting machine for preventing overlap marks on carbonless paper includes a predetermined outer radius, a predetermined relieved area and an outer circumferential surface, all dictated by various sheeter section operating speeds. At least one lobe projects from the relieved area out to the outer predetermined radius. Rotation of the overlap cam will enable the lobe to engage a clip of sheets traveling at high speed at a point displaced a predetermined distance from the leading edge of a clip for preventing compression of active CB and CF together during braking and thereby preventing an overlap mark from being formed on a previously decelerated clip while still performing braking action of a clip of sheets supplied to the overlap section of the sheeter.
