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. If a long roll of paper is on the platofrm, the support arm can be raised or lowered to spirally wrap the roll. This machine can also be used for originally wrapping the roll of paper with foam wrap and stretch film and a hold down device can be used to lock small or light rolls of paper onto the turntable.
