Abstract
Abstract A packaging apparatus for applying and heat sealing a sheet of material to another sheet of material having a plurality of uniformly spaced food receiving recesses therein and thereafter cutting the sealed pockets into individual packages, there being provided a heating platen against which one of the sheets is blown to soften the sheet with a die positioned on the opposite side of the heating platen into which the softened sheet is drawn or forced to form the pocket in the sheet. One of the sheets is fed from a supply roll holder assembly defined by an axially movable slide on a spindle that permits alignment of the supply roll with an adjustable retaining ring on the slide to accommodate for varying width supply rolls. There is further provided a plurality of retaining clips for holding one of the sheets during manipulation, supported on a chain drive with the clips being opened by a plurality of overlapping rollers that converge on actuating elements on each of the clips to open the same.
