  • Patent number: 10052709
    Abstract: Welding machine for edge-side connection at the edge of overlapping material webs, wherein the materials are connectable to one another under the effect of heat and subsequent pressure, with a chassis on which at least guide rollers, a heating device and at least one pressure roller are arranged. The heating device has a cantilevered contact heating element that can be inserted laterally between the edges of the material webs, wherein the chassis is driven by an electric motor which is arranged on a longitudinal leg of the chassis. The electric motor according to the invention is formed as a brushless DC motor and the reduction gear as a planetary gear, which are united by a drum drive motor. In this case, the direct current motor is preferably a disk rotor motor. The chassis has a lateral leg which is adjustable perpendicularly to the working direction relative to the longitudinal leg.

  • Publication number: 20150089905
    Abstract: A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing.

The two jaws (2) and (6) serve to render gas-and-liquid tight a top fin of a conventional, plastics-coated paperboard, gable-top carton. The ribs (12) and (14) produce, in the outer surface of one of the outer sealing panels of the fin, corresponding furrows which extend over the whole length of the fin at levels where the inner sealing panels are sandwiched between the outer sealing panels, so as to seal the top fin in a gas- and liquid-tight manner along its whole length.

  • Patent number: 7726103
    Abstract: A resilient backing member for use in cooperation with an impulse heating element comprises a resilient body having a longitudinal shoulder surface and a longitudinal intermittent raised edge protruding from the shoulder surface. The resilient backing member is for use in cooperation with an impulse heating element for sealing layers of thermoplastic film together and for either forming a sealed portion on the film, a rupturable portion on the film or severing the film. Accordingly, the resilient backing member can be used on a pouch filling machine to produce a string of sealed pouches connected by a rupturable portion or a sealed portion, and filled with flowable material without the use of a separate cutting blade.

  • Patent number: 7631473
    Abstract: A cutter-sealer (10) and a method (300) for cutting and sealing layers of film (70) together. The cutter-sealer (10) provides a heated blade (20), part of which moves through sheets of tautly held layers of film (70) into a slot defined by the seal pad (40). The blade's (20) motion is arrested by a set of blade shoulders (26) that press against the layers of film (70) for a period of time, thereby sealing the layers of film (70) together. The method (300) includes cutting layers of film (70) without liquefaction and sealing the newly cut edges of the layers of film (70) together, also without liquefaction of the layers of film (70).

  • Patent number: 7607911
    Abstract: A method and apparatus for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.
