Abstract: The present invention relates to a thermoform packaging machine and a method of operating a thermoform packaging machine, which comprises an infeed station and a pre-sealing station, so as to feed elongate products into troughs and retain them therein until a cover film has been fixed so as to cover the troughs.

Abstract: The invention relates to a packaging machine including a sealing device, said sealing device comprising at least a first and an individually controllable second sealing tool for producing a first and a second seal uniting a lower web with a top web.

Abstract: A sealing tool for a packaging machine comprises a sealing tool outer part, a sealing tool inner part that is movable in the sealing tool outer part, and a seal provided between the sealing tool outer part and the sealing tool inner part. The has a planar and annular design and is fixed in a first holding region at the sealing tool outer part as well as in a second holding region at the sealing tool inner part. The second holding region is disposed at or in the proximity of an outer edge of the sealing tool inner part.

Abstract: A deep-drawing packaging machine (1) includes a forming station (2) for forming containers (14) in a first web-like material (8), an insertion section (15) for inserting products (16) which reach at least one sealing level (28) or project over it, and a sealing station (3) arranged downstream thereof in a working direction (R) which is embodied to seal a second web-like material (10) onto the containers (14). The packaging machine further includes a means (11) for changing a distance (12) of layers (10a, 10b) of the second, at least two-layered web-like material (10). In another embodiment, a packaging machine includes an insertion section (15) and a sealing station (3) arranged downstream thereof in the working direction (R), in which at least one contact (25) is provided for thermal transfer via heat conduction between a sealing plate (22) and a heating plate (23) for heating a lid foil (10).

Abstract: The invention relates generally to a method for contact-free heating a thermoformable film prior to deforming the thermoformable film. Heating is carried out by at least one heater having at least one porous surface which faces the film and through which air flows. An air film is formed between the porous surface and the thermoformable film due to the flow of air through the porous surface. The invention also relates to a heating unit for contact-free heating a thermoformable film as well as to a packaging machine that includes such a heating unit.

Abstract: The present invention refers to a method for packaging foodstuff, particularly pizza, comprising a formed packaging tray and a formed cover film, wherein the space provided between the films and containing the foodstuff is gas-treated, and the cover film fixes the foodstuff in the packaging container.

Abstract: Changing or feeding, respectively, of a working tool (11) into a workstation (110) of a packaging machine (1) takes place by varying a distance of a receiving unit having arranged the working tools (11), with respect to a support rack (15) by means of a lifting device (200). By means of a shifting means (300) the working tool (11) can be shifted from the support (10) into the workstation (110), or reverse. Therein, the support (10) can be formed such that it is movable out of the packaging machine (1).
