An apparatus and process for foam wrapping pressure sensitive rolls of material in a limited amount of space with a minimum amount of handling of the pressure sensitive rolls. The apparatus includes an intermediate transfer cart and a retractable foam application unit. The intermediate transfer cart operates to receive unwrapped rolls of pressure sensitive material from a winder unit and transport it to a position underneath the foam application unit which custom wraps various widths of pressure sensitive rolls of material from one full width of foam web while providing a driving force to turn the pressure sensitive rolls as foam is being applied thereto.
