Abstract: A method for checking and correcting the position of a blank comprised of three flaps arranged in a row, the method including the following steps: closing the right- and left-hand flaps one above the other at least in an overlapping portion, gluing the flaps together; positional checking of the right-hand edge and the left-hand edge and comparing those edges with a predetermined position in order to determine a positional deviation of the flaps and, if the positional deviation exceeds an admissible deviation value, then before the glue sets, fixing the central flap at a location via the lower face of central flap using a fixing device using vacuum-induced negative pressing, then holding the upper face of the right-hand flap and of the left-hand flap by respectively at least one suction cup which applies vacuum, and correcting the position of the left-hand flap and/or of the right-hand flap by moving the suction cups sideways.

Abstract: The present invention relates to a transfer module (26) for a folder-gluer machine (1), the transfer module comprising a lower conveyor (36) and an upper conveyor (38) adapted to receive a folding box (2) therebetween and to transport the folding box in a direction of transportation (D) towards a downstream-located loading surface (90) in a stacker module. The upper conveyor (36) of the transfer module extends further in the direction of transportation than the lower conveyor (38) and the lower conveyor comprises a first conveyor belt (38a) and second conveyor belt (38b), each having an inlet end (67a, 67b) and an outlet end (65a, 65b), and wherein the outlet ends are displaceable in the direction of transportation.

Abstract: A device (10) for optically controlling a face (13) of a blank (12) has a vacuum conveyor (20) capable of transporting the blank (12) along a path of travel (15) and which includes a conveyor belt (22) having an apertured structure of which the conveying path follows the path of travel (15) of the blank (12). A suction device (40) is suitable for pressing the blank (12) against the conveyor belt (14). An inspection device (30) inspects the face (13) of the blank (12) during its conveyance by the vacuum conveyor (20). The inspection device is located on the side opposite the vacuum conveyor (20). The suction device (40) delimits three separate successive suction sections (41, 42, 43) along the path of travel (15), including a central suction section (42) that extends opposite the inspection device (30), an upstream suction section (41) and a downstream suction section (43).

Abstract: The present invention relates to a stacker module (28) for a folder-gluer machine (1). The stacker module comprises a loading surface (90) configured to receive a plurality of folding boxes and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector (76) configured to be moved from a retracted position (RP) to an extended position (DP).The stacker further comprises an upper guide (110), configured to move between a clearing position (CP) which is vertically distant from the upper surface of the stack, and a guiding position (GP), in which the upper guide is located closer to the upper surface of the stack, and wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the evacuation position.

Abstract: The present invention relates to a stacker module for a folder-gluer machine, the stacker module being located downstream of a transfer module in a direction of transportation of the folder-gluer machine and configured to receive folding boxes from a conveyor in the transfer module. The stacker module comprises a loading surface configured to receive a plurality of folding boxes in order to form a stack and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector configured to eject the stack from the loading surface. A front abutment guide configured to move between an abutment and a clearing position to retain and release the stack.
