ABSTRACT:
A machine for producing blister packages have several interchangeable dies with cavities, vented to the atmosphere, that differ in shape but have identical rim zones open toward an abutment plate through which compressed air is admitted for deforming a preheated thermoplastic carrier strip periodically pressed against that plate by the reciprocating die. The blisters thus formed in the carrier strip are filled with goods to be packaged and are then engaged by a transport wheel with peripheral indentations fitting around the invariable rim zones thereof, these indentations being separated by webs coacting with a counterroller to heat-seal the carrier strip onto an overlying metallic cover strip. Another, similarly indented transport wheel downstream of the sealing station, operating in a different rhythm, feeds the resulting composite tape to a die cutter dividing same into individual packages each having one or more rows of blisters.
