Abstract: The present invention relates to a thermoforming apparatus (1) for producing shaped bodies (114) of plastic sheet (50), such as cups, containers, lids, secondary packagings for foodstuffs or the like, which comprises a forming station with a two-part forming tool (20). The two-part forming tool (20) comprises an upper tool table (28) adapted to be adjustably fixed and having an upper tool (30) with pre-stretch means (92) movably mounted therein, and a movable lower tool table (32) having a lower tool (34) with cavities (112). The movable lower tool table (32) is guided through the intermediary of guide means (42) and capable of being approached to the upper tool table (28) and moved away from it. The guide means (42) in accordance with the invention for the first time include a rotatable guide rail assembly (40) whereby the lower tool table (32) may be guided rectilinearly and rotated together with it.

Abstract: A web-slitting machine has its blades mounted on cylinders shifted along a linear guide extending the full width of the web to be slit. The sliders carry tubes whose suction nozzles are disposed in the regions of the blades and which terminate in connecting heads having boat-shaped projections received between elastomeric sealing lips closing a slit of a suction box extending along the guide.
