Abstract: A method for folding a polymeric flat bottom bag. The process includes, in general, opening the partially folded bottom of the unfinished bag, pulling the bag bottom taught in the transverse direction, and forming a fin where the two material edges join. A sharp crease is formed between the fin and the base portions of the bag bottom, and the fin is sealed. The fin is creased and sealed while the bag is moving in its transverse direction. The bag's direction is changed, so that the bag is moving in its longitudinal direction, and the fin flaps then folded against the base of the bag bottom. The flaps are sealed to the bottom, resulting in a flat bottom bag. A label may be added to the bottom of the bag.

Abstract: A method and device are disclosed for raising rimpled and flattened parallelepipedic blanks to form rectangular parallelepipeds. A supply of flattened parallelepipedic blanks are rolled out in a first rolling direction through a pair of discharging rollers. Pressure is imparted on the flattened parallelepipedic blanks in a direction opposite to the first rolling direction by means of a pusher for opening the blank to nearly 180.degree. in a direction perpendicular to the rolling direction. The pusher is thereafter retracted in the first rolling direction to raise the blank to form a rectangular parallelepiped with a substantially square-shaped cross section. The formed blanks are thereafter unloaded from the device.

Abstract: Disclosed are carton assembling method and equipment for sucking and taking out flatwise folded cartons one by one from a magazine by means of suction cups, unfolding each carton squarely on a conveyance path while transferring it downward along a rotative path, and supplying the thus-unfolded cartons to an encasing machine by means of a conveyance mechanism. Each carton is held squarely by a pair of stoppers, utilizing its reaction force acting in the returning direction. Thereafter, the carton is reverse-folded against such reaction force and then unfolded again to remove the folding tendency of the carton acting in the folded direction, thereby permitting the carton to hold itself in a square shape. And at the time of reverse folding, the flaps of each carton are expanded so that a contents charging conveyor can be disposed in close proximity to the cartons.

Abstract: An apparatus and method for forming flat cut carton blanks into erected cartons with debowed carton side panels is disclosed. The apparatus includes a forming head receiving and directing a carton blank through forming guides. Pinching wheels rotatably secured adjacent the forming guides include a pinching notch with a leading edge projecting inwardly into the forming head path. The pinching notch engages the descending carton bottom and side panels to capture and pinch the fold lines and overbreak the side panels at the fold lines between the carton side and bottom panels. An inclined surface with a sharp creasing edge abutting the inside of the fold line assists the pinching notch in creasing the fold lines. An extension edge formed adjacent a trailing edge of the pinching notch completes the overbreaking action. A release edge formed adjacent the leading edge gently releases the carton side panels from the overbreaking position upon counter rotation of the wheel.

Abstract: In folding boxes forming a conveyor chain, rectangular, tubular carton blanks are introduced stepwise into two juxtaposed mirror-image designed folding stations. In the folding stations, the carton blanks are defomed by means of fingers and clamps so that their base surface is pulled into a parallelogram. The two edges forming the longer diagonal are pressed by means of stamping dies and by means of a counterholder and a stamping plate, respectively. After pressing, the carton blanks are pulled back into the folding boxes and are returned to their rectangular shape.

Abstract: An apparatus and method for forming flat cut carton blanks into erected cartons with debowed carton side panels is disclosed. The apparatus includes a forming head receiving and directing a carton blank through forming guides, side walls engaging and supporting the carton side panels that bend into upright position relative to the carton bottom panel during descending movement through the forming guides. Presser fingers pivotally secured to the forming guides project inwardly into the forming head path. The presser fingers bend the side panels into cutout openings provided in the side walls to overbreak the side panels at fold lines between the carton side and bottom panels. An inclined surface with a sharp creasing edge abutting the fold lines enables the presser fingers to initially crease the fold lines and thereafter bend the carton side panels inwardly onto the inclined surface for controlled overbreaking movement.

Abstract: A device for erecting and countercollapsing boxes from preformed blanks comprises a carrier arm pivotally attached to a chain drive and guided by a generally oval track to engage at a feed station the back edge of a blank for pushing the same through a pair of parallel guide slots along a path to an erecting station defined by rotary carrier synchronized with the chain drive for revolving a stopper to have, upon the emergence of the blank from the guide slots, a distance from the slots' exit substantially equal to the width of the blank and an orientation parallel to front and back edges of the blank. The stopper catches at the slots' exit the front blank edge and continues to revolve with tangential speed less than the speed of the arm, whereby relative motion of the stopper and the arm gives rise to a compressive force which opens and countercollapses a box from the blank.

Abstract: A box blank with receptacle and cover sections each with side flaps and end flaps has a hinge panel joining the two sections. A vacuum pickup draws a flat blank from a supply stack to a feed carriage which transfers the blank past sprays that apply glue to the end flaps. The speed of the carrier varies, but beneath the glue sprays speed is uniform. The carriage delivers the glue coated box blank to a former and a tray forming head having concave and convex interacting pressure plates which maintain doubled over end flaps of each section in a concave configuration with respect to the box while the folded end sections are adhered to form a box tray from the blank. Former flap benders cooperate with the tray forming head to shape the box tray. A second vacuum pickup clasps the formed tray at the hinge panel and draws a shaped tray from the forming head into engagement with folding elements such that the cover and receptacle sections are bent together along the hinge panel to form a closed box.
