摘要： The invention relates to a method for folding a corrugated cardboard blank (1) intended to form a folded box, the method comprising the following series of steps:
i) supplying a blank (1) comprising at least one longitudinal crease (11); ii) applying a liquid to the longitudinal crease (11) so as to make the corrugated cardboard more flexible at the location of the longitudinal crease (11), the application being performed by means of a liquid application arrangement (130) comprising a liquid-ejection nozzle (134) provided with a liquid outlet; iii) folding the blank (1) around the longitudinal crease (11); wherein an aspiration of liquid is produced inside an aspiration compartment (163) of the liquid application arrangement (130) during step ii). The aspiration making it possible to remove any excess liquid which might not have been absorbed by the cardboard and/or the cardboard dust produced.

摘要： A device for processing a plate element (35) has a rotable hub (52), two tools (57, 58), mounted on the hub (52) to process the element (35) when each tool is in a respective processing position; a drive to rotate the hub (52) and the two tools (57, 58); a rotatable counter-tool (64). The rotation (R) of the hub (52) varies during a rotation cycle of the hub (52), and includes two constant speed phases during each of which one of the two tools (57, 58) is, in succession, in the processing position; and at least one phase with each of the two tools (57, 58) in an intermediate position between the respective processing positions, so as to achieve a front lateral processing position and a rear lateral processing position on the element (35).
