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.

Abstract: A vertical foam wrapping machine can rewrap rolls of carbonless paper having damaged packaging in satellite locations without the need for returning the rolls of paper to the manufacturing facility for rewrapping. The machine includes a lift device with a vertically adjustable arm. Foam wrap and stretch film are positioned on this arm and are fed to the roll of carbonless paper resting on a turntable in front of the lift device. The turntable has a rigid platform upon which the paper sits. This platform is nonmovable relative to the turntable and has a diameter less than the diameter of the roll paper. In this manner, a lower section of the roll of paper adjacent the lower edge remains exposed. As the turntable rotates, foam wrap and stretch film are wrapped around the roll of paper. Due to the exposure of the lower edge, the foam wrap and stretch film can cover this lower edge. Accordingly, both the lower and upper edges of the roll of paper can be wrapped with protective foam wrap and stretch film.
