Abstract: 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.

Abstract: The present invention relates to a knife for a sealing jaw arrangement of a filling machine, the knife in use being provided in a first member, and designed to cooperate with a groove of a second member. The knife further has a body being provided with a cutting edge on one side thereof, the body further comprising a guide. The guide is configured to enter the groove for controlling a movement, in use, of the cutting edge into the groove, and the guide is configured to enter the groove before the cutting edge enters the groove. The invention further relates to a sealing jaw assembly having such a knife.

Abstract: 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 P1 downstream the gasket may exceed an ambient pressure Pa upstream the gasket.

Abstract: 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.

Abstract: 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.

Abstract: The disclosure relates to a packaging container and a method of producing a packaging container for liquid contents. The packaging container has a casing produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion and at the other end is connected to a top portion produced from a blow molded thermoplastic material. The casing is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam extending longitudinally of the sleeve, the top portion being manufactured in that thermoplastic material is extruded to form a hose which is blow molded into continuous top portions which are separated from one another and connected to the sleeve.
