A cutting unit for providing transversal cuts and/or perforations to a string of packaging containers connected by transversal seals is provided. The cutting unit comprises a knife assembly and an anvil assembly rotatable against each other to form a nip for receiving a transversal seal of the string of packaging containers. The anvil assembly comprises an anvil blade having a first region and a second region such that when the first region is aligned with a knife blade of the knife assembly at the nip a cut is produced, and when the second region is aligned with the knife blade at the nip a perforation is produced. A method, a computer program and a computer-readable medium storing the computer program for providing transversal cuts and/or perforations to a string of packaging containers connected by transversal seals are also described.

The disclosure relates to a filling machine () for filling a package () of a web of packaging material with a food product. The filling machine () comprises a jaw system () adapted to seal the package () after being filled with the food product. The jaw system () is equipped with means () for providing a unique mark () on the package (). The filling machine () further comprises a sensor () arranged downstream of the jaw system () which is adapted to detect the mark () on the package (), and a cutting knife () adapted to cut the package () from the web of packaging material. The cutting knife () is movably arranged in the filling machine (), such that the cutting knife () can be adjusted in relation to the package () based on the detected mark () before cutting the package () from the web of packaging material. The disclosure also relates to a method for filling a package () of a web of packaging material with a food product.

The invention relates to a sealing device () and a method for heat sealing packaging material for producing sealed packages. The invention also relates to a filling machine. The sealing device () comprises a first jaw () comprising an electromagnet (), and a second jaw () comprising a magnetic element (). The second jaw () is arranged opposite to the first jaw () to form a gap adapted to receive the packaging material, such that the first jaw () and the second jaw () are attracted to each other upon actuation of the electromagnet () to close the gap and clamp the packaging material between the first jaw () and the second jaw ().

A filling assembly for filling of a tube of packaging material having a seal starting at a first level, comprises a conduit arranged to lead liquid into the tube of packaging material below said first level and a passage arranged to eject gas through openings into the tube of packaging material below said first level. The filling assembly is characterized in that a gasket is arranged to provide a seal between said filling assembly and said tube of packaging material upstream said openings such that the overpressure Pdownstream the gasket may exceed an ambient pressure Pupstream the gasket.

The invention refers to a device () and method for sterilizing partly formed packages () in a packaging machine. The device () comprises an inner chamber () and an outer chamber (), the inner chamber () being provided with a sterilization unit (). Further, it comprises a carrier unit (), comprising a separating member () and a package carrying member (), which is being adapted to rotate between a first position in which the package carrying member () is located in the outer chamber (), and in which the separating member () separates the inner chamber () from the outer chamber (), and a second position in which the carrier unit () has rotated a package () into the inner chamber () and in which the separating member () separates the inner chamber () from the outer chamber ().

A centering support for a piston in a piston-type pump having a diaphragm extending between the piston and the cylinder to define a product end of the pump and a driven end of the pump includes at least three equally radially spaced, centering elements extending radially outwardly from the piston for contacting the cylinder wall. The centering elements define a gap between the piston and the cylinder wall. The centering elements are disposed on the piston spaced from the diaphragm at the product end of the pump.

A carton pulling assembly pulls a partially formed carton from a mandrel on a form, fill and seal packaging machine. The machine has a vacuum source for providing a vacuum and includes a machine controller. The partially formed carton has a sealed bottom wall. The carton pulling assembly includes a carton puller element movable in a reciprocating manner toward and away from the mandrel. A vacuum head assembly is mounted to the carton puller element for reciprocating movement therewith. The vacuum head assembly includes a cylinder and a finger configured for reciprocating movement within the cylinder having a suction element mounted thereto. The finger has a vacuum channel for communicating vacuum from the cylinder to the suction element. The finger is movable between an extended position in which the suction element contacts and engages the partially formed carton sealed bottom wall and a retracted position in which the reciprocating finger pulls the carton from the mandrel. The reciprocating finger moves toward the extended position by application of the vacuum to the vacuum head assembly while communicating vacuum to the suction element. A method for pulling a partially formed carton from a mandrel is also disclosed.
