Abstract: A working device (1) to be used on blanks running essentially in a planar manner within a folding and gluing machine, with the outer printable surface originally oriented downwards. First turning device (10) turns over each blank so as to position its outer surface on the top. A transport device (20) moves each blank with the outer surface on the top. An action device (30) implements at least one of printing the outer surface of each blank on the one hand and monitoring the outer surface of each blank on the other hand, while the outer surface is facing up. A second turning device (40) turns over each blank again in order to reposition its outer surface downward.

Abstract: A transport device for transporting sheet elements into a folder-gluer comprising two longitudinal support structures between which there extend one or more movement slides, one or more lead screws and a drive shaft for a belt. At least one longitudinal member supports at least one endless conveyor belt driven by the shaft. The longitudinal member is mounted in sliding connection on the movement slides and on the drive shaft and is in helical connection with the lead screws. A protecting device over the drive shaft blocks user access to the shaft. It is illustrated as a profile over the shaft and slide. The protecting device transversely connects the two longitudinal support structures.

Abstract: Folding device for folding blanks, including an internal tool fit to cooperate with an external tool for forming a longitudinal fold in a blank, and a supporting guide fit to cooperate with the internal tool to sandwich the fold as the external tool folds the blank as the blank is conveyed.

Abstract: 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.
