Definitions

  • the carton blank is provided with biasing tabs to urge the triangular folds of the carton blank into the proper position in readiness for folding of both the tray and lid edge flaps.
  • the invention relates to methods and machines for erecting a carton blank to a carton.
  • the invention relates to the erection of cartons which are comprised of a bottom portion in the form of a tray and a lid portion in the form of a further tray which is hingedly connected to the bottom portion and fits outside its side walls when closing the carton.
  • the invention relates to the erection of such bot tom trays and lid trays which at two opposite side panels are extended with edge flaps which are to be folded down against the insides of the side panels and are to be secured to these by means of gluing.
  • the bonding medium may be comprised of a heat sealable layer on the blank or it may consist of blue bead lines which are applied to the blank before it is pressed down into the shafts.
  • the carton in its erected position When in the shaft the carton in its erected position will be subjected to the action of pressure members which during a predetermined interval will act against those parts of the carton which shall be connected with each other through gluing. According to the known methods and machines the carton is thereafter subjected to a continued downward vertical displacement to the open bottom end of the shaft where the carton is delivered to a conveyor device.
