Abstract: A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.

Abstract: A cylindrical punch head (2) includes a punch face (3) and a side surface (4). The punch face extends in a radial direction about an axis of the punch head. The side surface extends in an axial direction of the punch head about a periphery of the punch face. The side surface defines a plurality of grooves (6). Each groove extends in the axial direction of the punch head. A method for shaping a paperboard bottom blank to shape a peripheral skirt portion about a periphery of the paperboard bottom blank using the cylindrical punch head.

Abstract: A coating device having a blade for metering a coating material onto a running web of paper or cardboard guided by a roll includes at least one noncontacting sensor disposed near the blade and between apparatus for adjusting the transverse profile of coating. The sensor provides a signal indicating the position of the blade. The device also includes a receiver for receiving the signal of the sensor and a control device for controlling the angular position of the blade as a function of the sensor signal. The angle of contact of the blade on the roll is determined as a function of the known pressing pressure (or a corresponding proportional value thereof) of the blade caused by the profile adjustment apparatus, preferably determined by a computer or microprocessor.

Abstract: An arrangement for dosing with a blade, in coating machines or similar, onto a running web of paper or cardboard carried by a roll in or with the arrangement. The blade is forced by means of a hold-down or several hold-down sections on the roll respectively the web. A transmitter transmits light, notably laser light. The blade features in the area between the contact line of the hold-down on it, and its contact line on the roll respectively the web, on its side away from the roll, at least one light-reflecting layer for reflection of the light ray directed by the transmitter at the layer. A receiver registers the position or angle of the ray reflected upon it by the light-reflecting layer of the blade. A controller is provided for controlling, dependent on the position signal of the receiver for the reflected light ray, the angular position of the blade, notably in its area between the contact line of the hold-down or the hold-down section and the roll.

Abstract: A coating blade adjustment system with a blade which on its one end is retained in a mounting and supported between this mounting and its working edge by one or several support elements. Between the support edge of the support element(s), in the area within or on the support elements, there is at least one measuring sensor provided for measuring the spacing of the blade from the measuring sensor for a precision adjustment.
