The present invention relates to a compact high speed carton erecting and sealing machine and method employing a horizontal blank feeding mechanism. Carton blanks are fed into the erecting station, positioned against a stop and vacuum erected from the trailing side panel. The erected blank is maintained in a squared position and driven through the machine by flights mounted on parallel chain conveyors adjustably positioned adjacent the long sides of the erected carton. As the erected carton is d...

A blank feeder is disclosed having a magazine with a delivery opening at one end and accommodating flat blanks as arranged from the one end toward the other end thereof in the form of a stack. The blank feeder also has a transport device having a path of transport extending straight from the delivery opening as a starting end to a terminal end away from the opening, and a device for unfolding each of the flat blanks to a tubular form of square cross section while the blank is being transported b...

A blank feeder is used for feeding blanks to a bottom forming mandrel. The blanks are initially in a flat form and are unfoldable to a form of square cross section. The feeder includes a magazine for the flat blanks, and a transport arrangement having a path of transport extending from the delivery opening along a circular arc having a central axis parallel to the widthwise direction of the blank in the delivery opening. The transport arrangement includes a suction member, a transport arm carryi...

A folding box gluing machine has a folding station in which portions of blanks provided with a glue strip are folded, and a subsequent transfer station which includes as a conveyor mechanism at least two pairs of conveying straps, each including an upper and a lower strap, and having a device for achieving the sideways removal of defective boxes arranged on the outside next to one pair of conveying straps. The upper conveying strap on at least one lengthwise side in the transfer station is suppo...

An apparatus automatically forms a paperboard blank into a container having a double glued side wall construction for providing an enhanced strength to the container. A platen drives the blank through mechanically powered forming rails for an initial folding of the blank into a partially formed container having a bottom, end and side walls, and inside corner supports. A compression plate and folding arms are biased against adhesive portions of the partially formed container for forming a fully f...

A method for making a longitudinal fold in a web, including the steps of: (1) providing a web-supporting device; (2) providing a folding belt disposed adjacent to a first longitudinal edge of the web-supporting device; (3) providing the web which is superimposed onto a web-contacting surface of the web-supporting device such that a first longitudinal edge of the web extends laterally beyond the first longitudinal edge of the web-supporting device and at least partially onto the folding belt; and...

A method for transferring cardboard blanks (7) in individual succession in a plant, comprising a store (1) for collection of cardboard blanks (7b), a conveyor (3), with an upstream portion (3a) which is designed to receive the cardboard blanks (7a), and a rotary collector-translator (2), comprising one or a plurality of orbiting gripper units (100, 200), wherein the cardboard blank is grasped in the store (1), extracted, translated and spaced, whilst being kept substantially parallel to the succ...

An aligning device including an upward straightening appliance consisting of a row of levers equipped with rollers, said levers being mounted for pivoting around a horizontal axis relative to a base member, said base member being mounted for pivotable movement around a vertical axis on a longitudinally extending member, each of the base members being connected by a flexible member to a corner piece shiftable relative to the longitudinally extending member to cause pivoting of all of the base mem...

A container erecting apparatus and methods are provided which advantageously increase the efficiency and production speed of erecting and sealing containers. The apparatus preferably includes a dispenser positioned to dispense one of a plurality of collapsed containers to be transported along a first predetermined path of travel and collapsed container erecting means positioned downstream from the dispenser for erecting the collapsed container. The apparatus also includes a first bottom panel fo...

A novel carton forming apparatus has a travel path along which carton members move in rapid, continuous succession, when the machine is in operation. During such movement, intermittently movable means fold an entire longitudinal wall portion of the blank inwardly at substantially one time; means is also provided to effect contact between the wall portion so folded and a cooperating portion, in such a manner that substantially all of an area that has been rendered adhesive thereon is contacted an...
