Method and apparatus for zigzag folding a material web

The application relates to a method for zigzag folding a material web, the method having the following steps: continuously feeding a material web to be folded into a folding apparatus along a feed direction, alternately gripping the material web in a proximal region of the folding apparatus by means of gripping devices, holding and conveying the material web by means of the gripping devices into a distal region of the folding apparatus, the material web being zigzag folded thereby, and releasing the material web from the gripping devices and depositing the material web in a stack (9) with folds in the distal region, a distance between adjacent gripping devices (4, 5) being equal to a fold length. Furthermore, the application also relates to an apparatus for zigzag folding a material web.

Packaging machine with transport chain

A packaging machine having several work stations, a transport chain and a chain deflection pulley on which the transport chain is mounted. The transport chain comprises chain clips, each chain clip having an upper part and a lower part, wherein the upper part and/or the lower part may be moveable relative to each other to move the chain clips between an open position and a closed position. The material blank may be introduced into the open chain clips and secured in the closed chain clips to transport the material blank in a direction of transport using the transport chain. A chain opening mechanism may be actively and operably changed between an opening state and a closing state in order to open and close at least one chain clip disposed on a planar oriented section of the transport chain and/or to maintain an already opened chain clip in an open state.

Device and method for conveying flat objects
10040655 · 2018-08-07 · ·

A device for conveying and transferring flexible, flat objects with a gripper conveyor including a plurality of grippers that are movable along a conveying path in a conveying direction, and further with a conveying-way device that forms a conveying rest that, in a transfer region, is arranged below the conveying path such that objects that are released from grippers in the transfer region are deposited onto the conveying rest. The device includes a pressing circulatory device that acts upon the transfer region and has a plurality of outwardly directed pressing arms. The pressing circulatory device is designed, in the transfer region, to press the objects to be transferred with the pressing arms onto the conveying rest such that the objects can be deposited onto the conveying rest in a guided and controlled manner.
