Abstract:
An adhesive applicator apparatus for putting into practice a method of adjusting the height a of a nip (53) between an adhesive applicator roll (5) and a nip roll (10) of an adhesive applicator apparatus for a web of corrugated board (47), comprisinga frame (1); an adhesive applicator roll (5), which is disposed in the frame (1) and drivable in rotation about a central longitudinal axis (8); a nip roll (10), which is disposed in the frame (1) and drivable in rotation about a central longitudinal axis (11), at least one of the applicator roll (5) and the nip roll (10) being a displaceable roll; a nip (53) between the adhesive applicator roll (5) and the nip roll (10) for a web of corrugated board to pass through, which comprises at least one liner web (50) and a corrugated web (49); a force sensitive device (34) for detection of an actual force which acts vertically on the web of corrugated board (47) in the nip (53); a distance adjusting device (36) for modification of the height a of the nip (53) by displacement of the applicator roll (5) and the nip roll (10) relative to each other substantially on a plane that is spanned by the central longitudinal axes (8, 11); and a control unit (43) for comparison of the actual force with a given nominal force in the nip (53) and for triggering the distance adjusting device (36).
