A thermoforming machine for manufacturing articles from a heated thermoplastic film includes a molding station, an extraction device, a hole punch; and a stacking station. The hole punch includes a pivotable lower punching tool which receives punched-out articles from the extraction device while being pivoted into a tilted position facing the extraction device and which pivots into a vertical 0 position to face an upper punching tool for punching operation.

Method and apparatus for processing a formable material

A method and apparatus for processing a formable material having at least first and second relatively repositionable units. The first unit has a sheet die, with the second unit having a rotary drum with a peripheral forming surface for receiving flowable material from the sheet die. The first and second units can be selectively changed between an operating relationship and a setup relationship, with the latter causing at least one space to be defined/enlarged and within which an operator can maneuver to gain access to a region of at least one of the first and second units. With the first and second units in the operating relationship, moldable sheets can be processed by causing the moldable sheets to be applied, and conformed, to the peripheral forming surface on the rotary drum.
