ABSTRACT:
An apparatus for fabricating a disc record package from a flat plastic sheet, comprising a narrow intermediate section interposed between a pair of panel portions. The apparatus includes a housing, a pair of substantially rigid planar folding plates pivotally mounted for movement, a rigid spacer plate, a means for selectively heating the narrow intermediate section of the said flat plastic sheet, and a means for folding the said rigid planar folding plates. The folding plates are operable between a spreadout co-planar position and a folded up juxtaposed position. The rigid spacer plate acts to form the central portion of the folded plastic sheet during the molding operation. The means for moving the said spacer plate and folding plates are pneumatically operated cylinders.
