The invention relates to a separating tool of a joining device, in particular for tubular bag machines, comprising a blade carrier (), which has a groove-like recess (), in which a blade () is arranged, characterized in that at least part of a wall of the recess () is designed as a bending beam, which extends over the length of the blade () and is integrally connected to the blade carrier () and adjacent to the base region () of the recess (), and that at least two clamping screws () are arranged on the blade carrier (), which clamping screws preload the bending beam () in the direction of the blade () in order to clamp the blade and are supported in threaded recesses () of the blade carrier ().

Separating tool of a joining device for flexible packagings

The invention relates to an apparatus for cutting a packaging material () for a package, comprising an ultrasonic welding device () that includes a sonotrode () and an anvil () for sealing the packaging material (), the sonotrode () being rotatable about a first axis of rotation (X) and the anvil () being rotatable about a second axis of rotation (Y). The apparatus further comprises a cutting device () which includes at least one knife () for cutting the packaging material () and which is arranged within the anvil (). The invention is characterized in that the knife () has a blade () with a cutting edge () that includes at least two tips () and at least two curved sections () interconnecting the two tips ().

Apparatus for cutting a packaging material for a package

The invention relates to a device for welding and separating a packaging material () for a package, comprising an ultrasonic welding device () with a sonotrode () and an anvil () for sealing the packaging material (), wherein the sonotrode () is rotatable about a first axis of rotation (X) and the anvil () is rotatable about a second axis of rotation (Y), and a cutting device () with at least one blade () for separating the packaging material (), which device is arranged in the anvil (), wherein the at least one blade () is arranged on the anvil () in such a way that a minimum distance () between the sonotrode () and a cutting edge () of the blade () is maintained, and so the packaging material () can be severed without any contact between the sonotrode () and the blade ().

Device and method for welding and separating packaging materials for a package

A sealing jaw for sealing a packaging material using ultrasound is provided. Said sealing jaw comprises energy directing means () which, for sealing purposes, can be brought in contact with an opposite surface () via the packaging material and which have a substantially grid-shaped or rhomboidal sealing profile ().

Sealing jaw for sealing a packaging material using ultrasound

A device and a method is proposed whereupon the device for processing a packing material using ultrasound comprises the following elements: at least one sonotrode (), at least one anvil (), whereupon a gap is constructed between sonotrode () and anvil () through which the packing material can be passed for the purpose of ultrasonically sealing a packing material, at least one adjustment means () that adjusts the gap (s) between sonotrode () and anvil (), at least one generator () that changes an input voltage into an output voltage, which a converter () transforms into mechanical oscillations in order to generate ultrasonic oscillations on the sonotrode (), whereupon a regulation device and/or control device () is arranged to regulate or control the gap (s) between sonotrode () and anvil () depending on at least one electric variable (P,E,R) that acts on the sonotrode ().

Device and method for processing a packing material using ultrasound

A device includes at least one bearing shield, at least one sonotrode which is rotatably mounted in the bearing shield, at least one anvil which interacts with the sonotrode to process the packing material, at least one other bearing shield to rotatably mount the anvil, whereupon a coupling mechanism is arranged to mechanically couple both bearing shields. The coupling mechanism is configured so that a relative motion between both bearing shields is made possible.
