摘要:
A container and a method of forming a container having a locking closure and a method of forming the locking closure. The container includes bottom, side and top walls and at least one of the walls being an opening wall formed of panels which provide an opening to an interior of the container and which overlap to provide the locking a closure of the opening wall. In a closed condition of the container, a bottommost panel of the opening wall is partially overlapped by adjacent panels of the opening wall and a topmost panel of the opening wall located opposite the bottommost panel partially overlaps the adjacent panels and the bottommost panel. A tab of the bottommost panel is lifted upwardly to partially overlap the topmost panel to form the locking closure.

Folding process of a blank of paper, cardboard, plastic, corrugated board or similar material used to carry out a folded box, the blank comprising a left longitudinal edge, a right longitudinal edge and from left to right, at least two respective longitudinal grooves delimitating at least two respective adjacent panels, the process comprising at least the successive following steps: a) folding at 180° of the panel around the longitudinal groove into a first folding device and formation of a longitudinal fold along the groove b) aligning of the said blank along the longitudinal fold into a main aligning device c) folding at 180° of the panel around the groove into a second folding device.

Sheet-folding machine, especially for packaging cases made of corrugated cardboard, after they have been produced and printed.It incorporates advancing (10) and folding (22) belts which are maintained at the exact cycle of the machine by means of pulleys (14) provided with recentering fingers (15). The conveyor belts are provided with suction elements (19), and the folding belts are provided with push-studs (25) arranged to correspond to the turned-down portions (5) to be folded.

A box making machine comprises a feed station, a positioning station, a printing station including four printing units, a cutting station with a creasing unit, a slotting unit and a cutting unit, a folding-gluing station and a stacking and delivery station, all driven by D.C. motors. The D.C. motors control is achieved by the electrical shaft coupling driven by a driving device which comprises a command control unit having a code generator, a synchronization circuit for each motor and a curved generator for one of the motors, a calculating unit including a microprocessor, input/output circuits and an input circuit with switches, a signal conditioning unit with an element for sense discrimination and multiplication, and a signal conditioner, and a command logic unit including a logic drive selection circuit, a logic starting circuit and a logic manual command circuit.
摘要:
A folding and tucking apparatus for a container end closure forming and sealing machine where a pair of oppositely rotating arms, each having a freely rotatable roller mounted on its distal end, are adapted to engage and move a heat-activated, plastic coated carton end closure panel around a score line from a vertical to a horizontal attitude. The result is that, while the rollers thus move the panel, the relative movement between the rollers and the panel is minimal, thereby preserving clean, unmarred surfaces on end panels of cartons which will be characteristically observed by consumers in the marketplace.

A carton blank may be folded by folder blades supported on an adjustable plate positioned on one side of a chain which carries a clamp by which the carton blank is pulled through the machine. After folding, the blank is glued to complete a flat shell and the shell is then inverted; the clamp is articulated so the shell may be turned in a horizontal plane to align a datum line on the shell to a datum line on a cartoner machine.

A reciprocable feeder arm (10) includes a projecting portion (12) for engaging an edge of a collapsed carton (C) in a hopper (1) and with the aid of a suction cup (13) removes the collapsed carton (C) from the hopper (1) and into a position adjacent but spaced from fixed suction cup means (3) into engagement with which one side wall (A1) of the carton is driven by movable suction cup means (4) which engages the opposite side wall (A) of the carton so that subsequent movement of the movable suction cup means (4) away from the fixed suction cup means (3) moves the carton side walls apart and tends to manipulate the carton into set-up condition during which movement a pair of spaced guides (6) engage end wall panels (B,D,B1,D1) at each end of the carrier and aid further in setting the carrier up while an arcuate fixed guide (6a) disposed adjacent the path of movement of the carton engages its bottom wall (E) so as to hold a pair of end flaps (F,G) foldably joined to the ends of the bottom wall are moved into approximately coplanar relation with the bottom wall so that a pair of fixed adhesive applicators (7) may apply adhesive to the inner surfaces of the end flaps (F,G) following which movement a reciprocable pusher element (8) engages the set-up carton (C4) along its upper edges and moves the carton between a pair of spaced plates (9) which engage the carton end flaps and force such flaps (F,G) into firm flat face contacting engagement with the end panels (B,D,B1,D1) at each end of the carton.
摘要:
A forming machine which permits a preformed corrugated board blank to be manually fed into one end of the machine, which blank has the rear flaps manually folded over and held until they are engaged by hold-down devices on the machine. The blank is moved through the machine by a drive belt and is sequentially acted upon by a folding structure which folds over the front corner tabs. A glueing device applies adhesive to the side flaps, and a further folding structure then folds over the side flaps for adhesive securement to the previously-folded corner flaps. The folding structure for the front corner tabs is nonpowered and includes levers for lifting the front tabs in response to movement of the tabs into engagement therewith, following which the front tabs are appropriately folded over while the side flaps pass beneath the lifting levers.
