And Heat Sealing Patents (Class 493/129)
  • Patent number: 11780197
    Abstract: The disclosure describes techniques for erecting cases, and particularly example structures and example methods for use in a case erecting system using a robotic arm. A tool for use in robotic case erecting may be used in conjunction with a robotic arm. Use of the tool assists in keeping a case level as the case moves along a conveyor, where a plow closes the major flaps and a tape head tapes edges of the flaps together, thereby sealing the bottom of the case. The tool also assists in regulating the gap between the major flaps, so that the gap and/or any overlap of the flaps is minimized. Accordingly, the tool assists the robotic arm to close the case in a more precise manner.

  • Publication number: 20140121088
    Abstract: A device for producing a three-dimensional structure from a receiver includes a deposition unit that deposits toner on the receiver. That unit is controlled by a controller to produce a toner pattern on the receiver. A fusing device includes first and second rotatable members having respective, different compliances and a mount that selectively retains the members with respect to each other to form a fusing nip and permits adjustment of respective forces between the members at each end. A directing unit entrains the receiver around the second member so that the receiver passes through the fusing nip. A softening device softens the toner of the toner pattern so that as the second member rotates through successive revolutions, corresponding layer areas of the receiver are defined and the softened toner in each layer area adheres to the second surface of the receiver in an adjacent layer area.

  • Publication number: 20100105534
    Abstract: A display pack for a consumer product is made of two sheets of corrugated cardboard and a clear plastic container with a flat insertion portion sandwiched between the cardboard sheets. The two cardboard sheets are adhered together in a peripheral area of the package by a heat-sensitive adhesive, and the corrugations of the cardboard sheets are crushed and flattened in the peripheral area. To seal the package, the peripheral area of the two cardboard sheets is subject to sufficient pressure to crush the corrugations inside the cardboard sheets and flatten them in that area. Heat is applied to the outer side of the cardboard sheets in the peripheral area and conducted to the adhesive material between the two sheets to activate the adhesive material. A sealer machine with a heated sealing press or parallel sets of heated rollers may be used to carry out the sealing process.

  • Publication number: 20100019020
    Abstract: The disclosure relates to a method of preparing a web of flexible material for production of receptacles for packaging. The method comprises the steps of feeding a web of flexible material past a succession of stations in which operations are carried out on the web including defining blanks for receptacles having walls and tabs by creating fold lines in the web, and then laminating a film of heat-sealable plastics materials to a face of the web of the flexible material. The film of heat-sealable plastics provides a heat-sealable surface on the web for bonding tabs of each blank together to form seams between adjacent walls whereby the blanks, when severed from the web, can be erected to form receptacles having openings to receive items to be packaged.

  • Patent number: 4562690
    Abstract: A package blank is made from a single sheet having at least surface layers of heat-sealable material. The blank sheet comprises first and second rectangular panels foldably formed on opposite sides of a backstrip. The first and second panels have first and second pairs of foldable side flaps, respectively, extending from their opposite sides, and the backstrip has a pair of foldable back flaps extending from its opposite ends. The first side flap pair and the back flap pair have sloping edges located adjacent each other for forming at least partly overlapping seams when the blank is folded up into a generally boxlike, open-front package. The overlapping seams serve to prevent the intrusion into the package of heated air used for fusing the second side flap pair onto the first side flap pair and the back flap pair.

  • Patent number: 4490129
    Abstract: In the forming of cartons, a water-based adhesive, e.g. an aqueous-dispersed polyvinylacetate, is applied as an atomized spray by guns to selected parts of a carton blank of uncoated board and partially dried by hot gas (air) jets, and the carton is erected by forcing the carton blank by a punch through a forming die so that the selected parts are pressed briefly against cooperating parts of the carton to secure them together, by means of projections on the punch and pressure members forming part of the die. The atomized spraying followed by hot air drying of the adhesive enables adhesion to be effected by very brief pressure, and the method can thus be used for high speed production of cartons of uncoated board.
