Abstract: 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.

Abstract: A measuring device for measuring a width (W) between a first edge (4) and a second edge (5) of spaced apart opposed edges (4, 5) of a slot (16) in a product (1?), comprising: a measuring part (18), with a measuring detector and a display (28), and provided with a first tab (37) configured to enter into the slot (16), and a slide (29), defining a longitudinal axis (X), being arranged so as to be adjustable relative to the measuring part (18) along the longitudinal axis (X), and provided with a second tab (46) being configured to enter into the slot (16). The slide (29) is adjusted so that a first surface (44) of the first tab (37) contacts the first edge (4) and a second surface (49) of the second tab (46) contacts the second edge (5). A distance (d) between the first surface (44) and the second surface (49) corresponding to the width (W) is detected by the measuring detector, and the value of the width (W) is displayed by the display (28).
