ABSTRACT:
Apparatus and method for making sealed packages for spreadable products includes means for transporting a relatively stiff base member carrying a spreadable product in the approximate center thereof, means for feeding a relatively thin flexible sheet material and for cutting such flexible material into predetermined lengths and for feeding such cut lengths to a rotatable vacuum drum having a plurality of die stations. There is a first tamper which cooperates with the die at the die station as the stations rotate past the tamper to shape each cut length of flexible material into a predetermined three-dimensional form. The three-dimensional form is transported by the vacuum drum to a position over the stiff base and the spreadable product thereon where the formed flexible sheet is released by the vacuum drum and cohesively joined along its outwardly extended edges to the base member to enclose the spreadable product positioned thereon. The longitudinally extending edges of the flexible sheet and base member are further pressed into cohesive engagement by a roller assembly which contains resiliently mounted blades which further compresses the leading and trailing edges into cohesive engagement. A final tamper then tamps the pleats shut. The spreadable product being packaged may also be shaped and sized by the tamper.
The top sheet is attached to the base member so that it can be peeled by the package user from the base member by pulling a peel tab to expose the product.
