摘要
The invention relates to a device (1) for use with a system (3) for thermoforming semi-finished goods (4), particularly for vacuum laminating a film element (5) on a carrier part, comprising a tenter frame (2) having a holding device (20) for holding a tool used to work the semi-finished goods, a pressure difference transducer (25) for producing a negative pressure or an excess pressure in at least one region (26) of the device (1) the pressure of which can be manipulated, spaces (30, 31, 32, 33) resulting between the tenter frame (2) and the holding device (20) and/or the tool, and a sealing device (40) comprising flat sealing elements (45, 46, 47, 48) for the face sealing of the spaces (30, 31, 32, 33) in order to seal off the at least one region (26) the pressure of which can be manipulated with respect to the surroundings (49), characterized in that a variable-surface sealing face (50) can be produced by at least one of the planar sealing elements (45, 46, 47, 48), by which the spaces (30, 31, 32, 33) can be sealed.
