The present invention relates to a method for portion-packing of an oral pouched snuff product (1′, 1″). The method comprises a) supplying and advancing a tubular web (19, 19′, 19″) of packaging material enveloping a continuous feed (23, 23′, 23a″, 23b″) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17′, 17″) for portion-packing of an oral pouched snuff product.

There is described a packaging machine for producing sealed packages of a pourable product from a web of packaging material, which may include conveying means for advancing the web of packaging material along a web advancement path at least to a tube forming station at which the web of packaging material is formed into a tube and for advancing the tube along a tube advancement path, an isolation housing having a main chamber and an auxiliary chamber arranged downstream of the main chamber along the tube advancement path, a tube forming and sealing device at least partially arranged within the main chamber and being configured to form and longitudinally seal the tube within the main chamber, a filling device for filling the tube with the pourable product and a pressure control device configured to control a first pressure within the main chamber and a second pressure within the auxiliary chamber such that the first pressure is higher than the second pressure and the first pressure and the second pressure are both higher than the ambient pressure.

A modular stand-alone ultrasonic bag sealing system has an ultrasonic sealer assembly that utilizes a sonotrode, an anvil that are actuated together to form a bag seal in a bag configured therebetween. The system also has an integral control system that is physically configured on the housing of the system and runs a control software. The control software is configured to control the ultrasonic sealer assembly to close and open to seal bags. The controller may have a plurality of signal inputs for receiving input signals from a bag feeder assembly or from an auxiliary machine. The system may also have an integral bag feeder assembly that has an index roller for feeding a bag to the ultrasonic sealer assembly. The system is configured for quick integration into a process line and has versatility of communication through the control software and signal inputs and outputs.

A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.

A system device and method for storing paint in which paint (2), either at a paint store or at home, is placed in a storage bag (1) that is sealed to create one or more packets (10). The packets may then be stored for use at a later date for touching up damaged or marked paint on walls and other surfaces.

A squeezable, flexible tubular package for an edible product is compartmented to simultaneously hold a first edible product in one compartment separate from a second edible product in another juxtaposed compartment. The package includes an elongated enclosure defined by a pair of transparent, flexible film strips bonded to one another around the periphery thereof by a liquid tight seal; and a membrane situated between the film strips, bonded to the periphery of the film strips by a liquid tight seal, partitioning the enclosure into a pair of juxtaposed, liquid tight compartments. An extrudable, edible product is separately contained in each of the compartments. Apparatus for continuously and successively forming, filling and sealing articulated arrays of such packaged products is also disclosed.

There is described a packaging apparatus for forming a plurality of sealed packages-comprising conveyor for advancing a web of packaging material along an advancement path, an isolation chamber, a tube forming device adapted to form a tube from the, in use, advancing web of packaging material, a sealing device adapted to longitudinally seal the tube, a support structure carrying at least the tube forming device, a filling device for continuously filling the tube formed by the tube forming device, a package forming unit adapted to form and seal the packages from the, in use, advancing tube formed by the tube forming device and filled by the filling device. The support structure comprises at least one support column at least indirectly carrying the tube forming device and extending parallel to the longitudinal axis of the tube forming device.
