An apparatus for forming a tray from a blank of sheet material is provided. The apparatus includes a platen configured to move along a path between a first position and a second position to drive the blank downstream from the first position and a first folding arm configured to fold an outside corner support member of the blank to form the blank into a partially formed tray including at least a portion of the outside corner support member being substantially parallel to the bottom panel. The apparatus further includes a fixed plate and a movable plate spaced from and movable with respect to the fixed plate. The fixed plate and the movable plate define a passage therebetween. The fixed plate guides the outside corner support member through the passage to a position adjacent a side panel and/or an end panel.
Abstract:
A modification of conventional case packing equipment for forming rectangular containers from knocked-down-flat (KDF) precursors allows formation of non-rectangular containers having one or more oblique wall panels, e.g., an octagonal container. As part of a conveyor line operation, a ram head assembly is advanceable into a rectangular tube erected from a KDF container precusor. The ram head assembly includes a pair of plows which are movable outwardly from a base of the ram head assembly and into engagement with opposing interior sides of the rectangular tube such that oblique corner wall panels are positively formed along score lines provided in the precursor. In addition to forming the oblique wall panels, the plows provide pressing surfaces for facilitating adhesive securement of the container closure flaps while the plow maintains the oblique wall panels in a proper orientation. Once the closure flaps are secured, the container shape is stabilized, the plows are retracted out of engagement with the container walls, and the ram head assembly is retracted from the resultant container.
Abstract:
An octagonal box structure comprising eight upstanding side wall panels and eight closure flaps integrally connected to one another and to the side wall panels for folding inwardly along a generally horizontal score hinge line to close an end of the box structure. The side wall panels include four smaller panels having a width dimension of about 20 to 40 percent of the width dimension of the narrowest pair of the remaining four side wall panels. The closure flaps have a width corresponding to the width of the side wall panel from which they depend. Four of the closure flaps include diagonally extending score hinge lines to permit each of these closure flaps to fold inwardly in partial overlapping relationship upon itself and the next adjacent closure flap to form a closed end of the box. The diagonal score lines are formed at an angle between about 20 to 25 degrees relative to an extension of the vertical score lines which define the width of each closure flap.
Abstract:
Apparatus and method are provided for setting up a basket-type carrier from a collapsed state. The carrier includes pair of foldable end panels connected to opposite ends of a slotted base panel, side panels foldably connected to opposite sides of base panel, and pair of foldably connected panel sections forming a handle. Each end panel has foldably connected upper and lower sections initially in face-to-face relation. Each upper section has side segments foldably connected to ends of the panel sections. A U-shaped insert piece is assembled with the carrier and has upstanding legs extending through the slotted base panel and retaining the handle panel sections in face-to-face relation. The panel sections of the collapsed carrier are in coplanar relation and when the collapsed carrier is at a first station, external force is applied to the panel sections causing same to fold relative to one another into upright face-to-face relation. As the panel sections move to face-to-face relation, the upper and lower sections of each end panel partially unfold. The carrier is moved to a second station wherein the upper and lower sections of each end panel assume an upright coplanar relation. The carrier is moved to a third section wherein adhesive is applied to areas of the side panels. The carrier is moved to a fourth station during which the side panels are folded to upright positions and secured to the end panels. The insert piece is assembled on the carrier slotted base panel at a fifth station.
Abstract:
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 formed container having a double glued side wall construction.
Abstract:
A number of cases are stored horizontally in a stack in a magazine. A bottom upper-inner flap of a flat folded case is folded downward to open the case by a flap-folding member while the case is being lifted from a magazine station to a flap-folding station, and while attracted to and held by a suction cup. The case is opened during this lifting and folding step. Once the bottom upper-inner flap has been folded downward, it comes into the space between the bottom outer flaps. The bottom upper-inner flap, which has been folded downward, pushes the left outer flap during the lifting operation. As the case is lifted higher and higher, both outer side flaps are opened simultaneously. The case is therefore gradually opened, during lifting, thereby forming a hollow cylindrical case. The remianing bottom flaps are closed and then sealed.
Abstract:
Apparatus for facilitating the manual erection and loading of a partially assembled paperboard carton blank. The machine includes a work table on which the carton blank is manipulated selectively to open the blank and close the bottom thereof by utilizing a vacuum system for selectively restraining major flaps forming the bottom wall of the carton. The opened carton blank remains immobilized on the work table for loading through the open upper end thereof. The major and minor flaps at said upper end then can be folded manually to close the loaded carton, after which the vacuum system can be deactivated to permit sliding of the loaded carton into a takeaway apparatus which can be a taping or sealing device or a conveyor for transporting the loaded carton to a remote work station, such as, for sealing. The table top may be pivotal. Also, the table top is provided with guide means for positioning the blank properly on the work table; said guide means can be adjustable for accommodating different sizes of box blanks thereon.
Abstract:
In an egg box made from slitted cardboard blanks of which one provides wave strips joined only at their wave crests for folding around to make pockets for the eggs and the other blank provides flat bottom and side panel or cover strips which brace the wave strips by being glued to the wave trough bottoms of the wave strips, top cover strips respectively glued to the half width wave strips that come together (when the top wave strips are folded around the eggs already packed in the pockets previously formed,) do not both correspond in width to the top wave strips, but one of them has an overlapping free edge the underside of which is bonded adhesively to the other top panel strip. The adhesive bonding is done with a hot-sticking adhesive which when cooled without being covered is no longer sticky. The adhesive is laid down in strips on the wider and shorter blank which provides the cover strips at locations corresponding to the wave trough bottoms that are to be glued on. While it is hot the longer and narrower wave blank, bent into waves, is glued on, leaving the edge portion of the wider blank with spaced cross-ribbons of adhesive which are allowed to cool so that they are no longer sticky. The glued blanks are then filled at a packing station but before they are folded to make pockets, for the eggs, the free edge strip is heated with hot air to soften the adhesive ribbons and then the box is set up and filled and after the top of the box is folded into place, the overlapping free edge strip is pressed against the underlying cover strip to stick the two together. When the adhesive has cooled the pack is secured.
Abstract:
Apparatus for erecting a bottle carrier. The carrier is initially formed as a flat folded tube having a bottom wall, a top wall and transversely creased end walls, the top wall forming a central partition. The apparatus has a longitudinal partition former which is spaced to create a longitudinal slot and end formers which are spaced from the longitudinal formers to create end slots. A blade passing through a hole in the bottom wall engages the inside surface of the top wall to drive it into the longitudinal slot. This operation creates the central partition and simultaneously erects the end walls as the carrier is thrust into the forming apparatus.
Abstract:
A machine to erect flat-folded cartons, especially such as carry beverage containers, from a flat-folded storage configuration to three dimensional carrying configuration. The machine feeds folded containers from a storage hopper, in singulated fashion, between two endless forwardly flaring vacuum belts which hold the carton sides and move them simultaneously therealong to initialy expand the container. The partially expanded container is then completely expanded and fastened by a cooperating over-head positioning chain structure and an underlying cam wheel and thereafter delivered for further operation. The assembly operations are sequentially timed. The vacuum belts are particularly configured to allow a continuous, rapid operation with low air flow.
