In the case of a thermoforming system, it is provided, for the purpose of changing over the moulds (11, 12) in a station (1) of this system, that one (4) of the two transporting devices (3, 4), for transporting the sheet (7) from one station to the other, can be displaced in the direction of the oth

In the case of a thermoforming system, it is provided, for the purpose of changing over the moulds (11, 12) in a station (1) of this system, that one (4) of the two transporting devices (3, 4), for transporting the sheet (7) from one station to the other, can be displaced in the direction of the other transporting device (3), transversely to the conveying direction, in order to create space on one side of the lifting tables (9, 10) so that it is possible for the mould block (11, 12) to be moved out of the station onto a mould-changing arm (13) and, from there, onto a mould-changing carriage (15).

The invention claimed is: 1. Thermoforming system having at least one station (1, 2, 5) for producing or processing moulded parts which can be produced from a sheet (7), in the case of which the sheet (7) is gripped along two longitudinal borders by a first and a second conveying device (3, 4) and can be conveyed through said at least one station in a conveying direction, wherein the first conveying device (4) can be transferred, transversely to the conveying direction, from a first operating position into a second position, in which it is possible to exchange a mould (11, 12) or arrangement serving for producing or processing the moulded parts irrespective of a travel or displacement which can be executed by a table or tables (9, 10) or by some other supporting arrangement supporting the mould (11, 12) or said producing or processing arrangement, wherein the second position of the first conveying device (4) is alongside the second conveying device (3), on one side between said tables (9, 10) or said other supporting arrangement, thereby freeing space on the other side between said tables (9, 10) or said other supporting arrangement. 2. Thermoforming system according to claim 1, wherein the conveying devices (3, 4) used are needle chains, roller chains, belt drives, or clip chains. 3. Thermoforming system according to claim 1, wherein the first one conveying device (4) can be displaced parallel alongside the second conveying device (3). 4. Thermoforming system according to claim 1, wherein a width-adjusting device (16) for the conveying devices (3, 4) that are parallel to one another is provided for the purpose of displacing the second conveying device (4). 5. Thermoforming system according to claim 1, wherein each of said first and said second conveying devices (3, 4) is configured so that it conveys the sheet (7) in the conveying direction which is a single, one-way conveying direction. 6. Thermoplastic system according to claim 1, wherein said first and second conveying devices (3, 4) are configured to grip along two longitudinal borders the sheet (7), which is provided rolled up on a reel (6).
