A machine including a first deck, a second deck, a first blank transfer assembly, and a second blank transfer assembly is provided. The first and second decks are coupled to a frame. The first blank transfer assembly extends from a first end to a second end and includes a first pick-up assembly moveable between the first end, proximate the second deck, and the second end, proximate the first deck. The second blank transfer assembly extends from a third end to a fourth end and includes a second pick-up assembly moveable between the third end, proximate the second deck, and the fourth end, proximate the first deck. The first blank transfer assembly and the second blank transfer assembly are operationally offset when moving between the first and second ends and the third and fourth ends, respectively.

In erecting a carton from a knock-down carton blank, the blank is placed on a base of a bed of a shuttle such that a bottom side panel of the blank abuts the base. The bottom side panel of the blank is then gripped with a gripper of the base and a top side panel of the blank is raised while advancing the shuttle in a horizontal direction so as to open said knock-down carton blank into a carton sleeve.

A method for checking and correcting the position of a blank (10) that includes closing the folded right-hand and left-hand flaps (17, 18) of the blank, which are positioned one above the other in an overlapping portion, checking the position of the right-hand edge (13) and of the left-hand edge (14), and comparing the position with a predetermined position in order to determine a positional deviation, if the positional deviation exceeds an admissible deviation value, and before the glue sets, fixing of the central flap (19), then holding the upper face of the right-hand flap and of the left-hand flap by a suction cup (21, 23, 24, 26), and correcting the position of the left-hand flap (18) and/or of the right-hand flap (17) by moving the suction cup (21, 23, 24, 26).

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

A main die-cut element is divided along a predefined division line to obtain a first die-cut element and a distinct second die-cut element. Glue is deposited on a first portion of one from between the first die-cut element and a secondary die-cut element and on a second portion of one from between the second die-cut element and the secondary die-cut element. The method includes forming an opened die-cut element of the tray plus lid type given by the combination of the first die-cut element and the second die-cut element, wherein these two elements are coupled to the secondary die-cut element, with the first die-cut element and the secondary die-cut element partly superposed and pressed to one another at the first portion and the second die-cut element and the secondary die-cut element being partly superposed and pressed together at the second portion.

A line and method for the production of covered cardboard boxes are disclosed. The line includes a conveyor unit including a belt and a conveyor actuator that drives the belt intermittently in an alternating sequence of movements and stops. A feed unit individually feeds covering blanks from a reservoir to the conveyor unit in a sequence of feed instants. An erecting machine folds box blanks into corresponding boxes. A positioner individually positions the boxes from the erecting machine, in alignment on corresponding covering blanks disposed on the belt of the conveyor unit. A gluer spreads glue on one face of the covering blanks. A covering machine folds the covering blanks into contact with their respective boxes to cover the boxes. A control unit connected to the feed unit adjustably sets a phase displacement of the feed instants relative to the sequence of stops of the belt.
