  • Patent number: 5595340
    Abstract: A fin-sealed, flat-topped, liquid-packaging carton with substantially triangular flaps of its tope end closure turned down and tacked to adjacent body panels has the horizontal part of its fin heat and pressure adhered to the top wall along approximately only that half of its length further from the triangular flap which will provide a pouring spout so that turning upwards of the spout end of the fin from its position flat against the top wall tends to pull upwards the central part of the top wall. Two score lines extending divergingly from the spout end of the top wall at respective opposite sides of the fin to respective corners of the opposite end of the top wall are thereby broken outwards rather than inwards.

  • Patent number: 4819410
    Abstract: Filled and top-sealed cartons are fed in a line to a chamber supplied with dehumidified warm air and short rows, each of two or three cartons, are pushed consecutively and laterally at a grouping station by a vertical plate onto a carrier, which advances the rows in turn through a side-taping station. At the grouping station, a tape-gripping device draws off consecutively from a roll of non-adhesive tape predetermined lengths of the tape, which are gripped at their middle sections in turn and are cut off from the roll, the cut-off end zones falling down to respective opposite sides of the row. The cut-off lengths are advanced with the respective rows through the side-taping station, which has a pair of adhesive-tape-applying rolls at those respective opposite sides and at which respective side tapes are applied to adhere together the cartons of the row and the handle of the row.

  • Patent number: 4518377
    Abstract: A gable-topped carton blank is cut from paperboard coated on both faces with thermoplastics. In the top closure, a loop of sub-panels provides a sealing fin. Each of two opposite sub-panels is folded inwardly upon itself and one is opened-out in forming a pouring spout. To reduce the tendency for the internal surface middle zone of this sub-panel to adhere to the internal surfaces of two other upper sub-panels during heat-sealing, these latter surfaces are formed in the blank with embossed recesses corresponding somewhat in position with recesses in sealing jaws.

  • Patent number: 4202191
    Abstract: A cold forging machine comprises a fixed die 11 and a movable punch tool 13 reciprocable towards and away from the fixed die to act on a workpiece therein. The tool comprises a tubular punch 34 and extrusion pin 33 movable through the punch to form a bore in the workpiece. The die is provided with a tubular ejector 15 in which slides a carrier pin 16 to enter the bore of the formed workpiece to guide it during ejection. A fault detection system includes a switch 25,61 for detecting non-completion of the normal movement of the carrier pin 16 with respect to the ejector 15, and a further switch for detecting non-completion of normal movement of the extrusion pin 33 with respect to the punch 34.
