摘要： In order to avoid having to remove grippers that are not required from the machine when changing the number of lanes by disconnecting the supply lines, in particular pneumatic lines (which requires a great deal of effort due to the hygiene regulations when reconnecting later) the gripper that is not required, at least its base part, ideally together with the gripper head fastened to the base part, is removed from the operating position and repositioned to a parking position without having to disconnect the supply lines. The same is also optionally possible with the contact pressing units of the PFOs, whose contact pressing drives are also connected to supply lines, usually pneumatic lines.

摘要： A thermoforming packaging machine that includes a film holder for receiving a lower film supply roll and one behind the other in a sequential arrangement along a production direction a pretreatment station for pretreating the lower film web, a forming station for forming troughs in the lower film web by thermoforming, an insertion line for filling the troughs with products and a sealing station for sealing the troughs with a top film. A transport device is configured to transport the lower film web along the production direction through the pretreatment station, further to the forming station, further to the insertion line and finally to the sealing station. A deflection unit arranged at least partially below the pretreatment station is configured to deflect the lower film web before reaching the pretreatment station. The pretreatment station may include a punching or slitting unit to punch or slit the lower film web.

摘要： A packaging machine, comprising a control unit, a plurality of measuring devices and a plurality of working units for different processes. The control unit is functionally connected to the working units and the measuring devices. A work cycle at the packaging machine comprises at least a first functional process and a second functional process at one or at different working units, the second functional process starting later than the first functional process. The control unit may execute an early start for the second functional process of a working unit, when an actual process value of the preceding first functional process of the program sequence of one of the working units has not yet reached the respective target process value. The control unit may control the early start of the second functional process based on an approximation method for predetermining the temporal end of the first functional process.

摘要： A method for operating a packaging machine including one or more of the method steps advancing a transport chain along a chain deflection pulley, wherein chain clips are arranged on the transport chain and moved during the advancing motion of the transport chain along a run-on contour, to open at least one of the chain clips; introducing a flat material blank into the at least one open chain clip using a feed device or by entraining the flat material blank using a connection to a second material blank preceding the flat material blank, wherein the material blank enters the open chain clip during an advancing motion of the transport chain; closing the chain clip by leaving the run-on contour, to grip and secure the material blank in the chain clip; and transporting the material blank to a work station using the transport chain.

摘要： A packaging machine comprising a machine frame, an area of protection and a protective cover. The protective cover, when disposed at a protective position, shields the area of protection at least partially against access from outside the packaging machine. The protective cover may be fully removable from the machine frame as well as lockable on the latter at an access position. The protective cover, when occupying its access position, allows access to the area of protection of the packaging machine. The machine frame may have a locking lever arranged thereon, wherein the locking lever is configured for retaining the protective cover at the access position. The locking lever may extend through an opening in a wall of the protective cover when the protective cover is disposed at its access position.

摘要： A packaging machine comprising a machine frame and at least one workstation with a lifting gear for supporting and moving a lower tool part between an open and a closed position. The workstation may include an upper tool part to act in cooperation with the lower tool part during a working operation. The lower tool part may be engaged with or near in proximity to an upper tool part in the closed position, and will be spaced apart from the upper tool part in the open position. A tilting mechanism is provided for a tool changing operation to tilt the lower tool part into a tilted position when the lower tool part is in the open position. In one embodiment, the lower tool part is removed from the packaging machine on a rail system in the direction corresponding to the tilted position.

摘要： A packaging machine comprising a machine frame, at least one work station attached to the machine frame, and a transport device with a transfer unit for feeding trays to the work station, wherein the transfer unit comprises a suction plate for transporting trays in a predetermined transport plane. The suction plate may comprises at least one reception mold which is formed at least in part having the shape of an inner contour of an upper opening region of a tray facing it, provided to the reception mold for reception and transport, so that the reception mold during transport in the transport plane of the tray is arranged in a positive-fit manner in its upper opening region and aligns the tray in the transport plane in a predetermined position on the suction plate. The invention also relates to a method for supplying trays to a work station of a packaging machine.

摘要： A reclosable package, and a machine and method for making that reclosable package that includes a tray for receiving a product and a substantially horizontal edge, wherein the horizontal edge extends circumferentially on an upper side of the tray and has a clamping portion releasably connected thereto. The package includes a top film across the tray, the edge and the clamping portion, and which may be releasably connected to the edge by a first sealed seam to seal the tray in a gas-tight manner. The top film may be connected to the clamping portion by a second sealed seam. A side face of the tray may include an undercut provided with a projection, the projection being suitable for locking the clamping portion in position when the clamping portion has been detached from the edge and is located between the projection of the undercut and the side face of the tray.
