摘要:
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.
摘要:
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).

摘要:
The present invention relates to a work station for a packaging machine, comprising an upper tool and a lower tool arranged below the upper tool. These tools are configured for acting on a packaging web. A lifting unit is able to move the upper tool and/or the lower tool such that, at a specific position, the two tools abut on one another or are only spaced apart at a small distance. According to the present invention, the two tools are adapted to be coupled to one another by a releasable coupling at this position so that they can be removed from the work station in common. The invention also relates to a corresponding method for removing a lower tool from a work station, e.g. for the purpose of tool exchange.

The present disclosure relates to a thermoform packaging machine comprising at least one cross cutting station including a punching device for cutting out strip cuts and a method of operating such a thermoform packaging machine.
摘要:
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.
摘要:
A thermoforming packaging machine according to the disclosure comprises a forming station for producing packaging troughs in a bottom foil, and a filler for filling the packaging troughs with products. The filler is arranged at a transition region for conveying the packaging troughs from a first transport plane to a second transport plane. A corresponding method for filling packaging troughs with products is also provided.
摘要:
The invention relates to a tool changing device of a work station in a thermoform packaging machine, used for allowing a work insert to be removed from the work station laterally relative to the working direction, said tool insert being adapted to be raised to a position above a chain guide on at least one side.
摘要:
The disclosure relates to a winder for winding film trims for packaging machines. The winder comprises a drive, a winding mandrel and at least two winding rolls. The disclosure is characterized by an adjustment device for adjusting a torque threshold above which slip occurs between the respective winding rolls and the winding mandrel and/or between the individual winding rolls.
