Claim:
1. A device for manufacturing containers by thermoforming from a sheet of thermoplastic material moved step by step from upstream to downstream, the device comprising, from upstream to downstream, a heating station where a plurality of delimited blank zones in the sheet of thermoplastic material are heated, a cutting station having cutting assemblies to simultaneously cut out adjacent individual blanks in said heated zones of the sheet, and a thermoforming station comprising a plurality of thermoforming assemblies each comprising a thermoforming chamber and a piston mobile back-and-forth in a piston liner, a spacing between the thermoforming assemblies being higher than a spacing between the cutting assemblies and the device comprising a plurality of individual gripping members configured to adopt a first state in which a spacing between said gripping members corresponds to a spacing between the cutting assemblies, to simultaneously take hold of individual blanks at the individual cutting assemblies in said first state, to be drawn apart to a second state at which a spacing between the gripping members corresponds to a spacing between the thermoforming assemblies and to simultaneously deposit the individual blanks in the thermoforming assemblies, and wherein the gripping members are heated.
