Abstract: A device for welding a plurality of foils to one another by means of a laser, for use in a packaging machine, comprises a clamping unit configured for applying pressure to a plurality of foils in a predetermined area as well as for conducting the laser radiation used for the purpose of welding to this area. A method for welding a plurality of foils to one another by means of a laser in a sealing station comprises welding the foils to one another along a sealing seam by means of the radiation of the laser while pressing them together in the area of the sealing seam.

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 to a method for closing already preformed and separated containers (19), for example trays, with a lid foil (24) in a closing station (3). The invention is characterized in that a deep-drawable foil is used as lid foil (24), that the lid foil (24) is deep-drawn in a forming means (23) of the packaging machine (1), and that the deep-drawing of the lid foil (24) is accomplished before the containers (19) are closed with the lid foil (24). The invention also relates to a packaging machine (1) suited for carrying out such a method.

Abstract: Proposed is a packing machine (1), in particular a roller or deep drawing machine, tray sealing machine or the like with components which have to be cleaned regularly, in which machine the cleaning of the components to be cleaned is improved. This object is achieved in that the packing machine (1) comprises a fluid supply unit (16) for providing at least one cleaning fluid.

Abstract: The invention proposes a chain for a machine drive, transport of material in a machine or the like, and also a packaging machine comprising one such chain, this chain being better than known link chains at meeting requirements in respect of hygiene conditions during operation and cleaning. This is achieved according to the invention in that flexible chain links (4) are provided between rigid chain links (2), the flexible chain links (4) being fixed to the rigid chain links (2).

Abstract: The invention provides a packaging machine support device having a frame with side walls and feet which bear the latter, and having at least one workstation borne by this frame, the side walls being in profile form. The packaging machine support device in accordance with the invention is suited to comply with the increasingly stringent hygiene requirements for packaging machines. This is achieved according to the invention by providing a frame profile (7) that is essentially open at the sides.

Abstract: The present invention relates to a packaging machine having an ultrasonic device (1), the ultrasonic device (1) comprising: an ultrasonic generator (2) which generates electric vibrations; an ultrasonic converter (3) which converts the generated electric vibrations into mechanical vibrations of the same frequency; a transformation intermediate piece (4) which transfers the mechanical vibrations to a sonotrode (5); the sonotrode (5) comprising a sound-radiating end surface (6) at which it reflects the mechanical vibrations, so that a standing wave to be passed into a packaging foil (18, 19) is formed, and the sound-radiating end surface (6) being disposed in a vacuum and/or in a modified atmosphere.

Abstract: The present invention relates to a packing machine 1 for the packing of packed items, in particular encompassing a deep drawing machine 3 with a mold and/or a sealing device with a sealing tool. The packing machine is distinguished in that a cleaning device is provided for the mold and/or the sealing tool. Furthermore, the present invention also relates to a deep drawing machine and a sealing machine.

Abstract: The invention relates to a packaging machine comprising at least one working station, in which a film is acted upon by means of underpressure or overpressure, characterized in that the pressure and/or the volume flow is regulated by means of a proportional controller.

Abstract: The invention proposes a packaging machine having a frame which comprises side walls and feet which bear the latter, and having at least one workstation borne by this frame, the side walls being in profile form. The packaging machine according to the invention is intended to meet the increasingly stringent hygiene requirements to better effect. This is achieved according to the invention in that the profile (7) is essentially open at the sides.

Abstract: A packaging machine comprises a base frame having an input side and an output side as well as a transport path from the input side to the output side. A plurality of tray carriers for holding trays are arranged in succession from the input side to the output side along the transport path. A drive means advances the tray carriers in an advancement plane. Further, feed means are provided for feeding a cover film for covering the filled trays. Successive tray carriers are pivotally interconnected by means of pivoting coupling links. Each tray carrier has engagement elements provided at its forward and rearward side. The drive means is formed as a drive chain with a chain strand trained over chain wheels and the engagement elements engage the chain strand when in a position adjacent thereto.

Abstract: A packaging machine comprises a frame, at least two work stations arranged behind each other and carried by the frame and transport means for advancing the packaging material. In order to simplify the manufacture and to reduce the weight of the frame parts the lateral frame parts have a substantially U-shaped cross-section having an upper cross-link and two downwardly directed sidewalls. The free ends of the sidewalls are connected by connecting members.
