Abstract: Production machine which automatically rapidly continuously heat-seals blister packs of pharmaceutical capsules into match book-like covers coated on interior surfaces with a heat-sealing composition and provided on outer surfaces with descriptive printed material. The machine deposits these covers in a folded condition onto flights spaced uniformly transversely across an endless conveyor chain, opens the folded covers in order to receive the blister packs between sealing flaps and back covers of the match book-like covers, heat seals the blister packs therebetween, and then folds front covers thereover prior to packaging. Several operations are necessarily synchronized with continuous stop-and-go movement of the chain by means of cams, linkages, and pivoting members.
