Method and apparatus for production of laminated and shaped wall covering board of corrugated paperboard base
 In the production of a wall covering board which is shaped and composed of a substrate of corrugated paperboard and a decorative and/or protective skin layer, a hot-press for bonding of the skin to the substrate either simultaneously with or subsequently to shaping of the substrate is combined with a skin material support mechanism and a drag mechanism including a sheet-grasping device mounted on the piston rod of a piston actuator. The support mechanism supports, with friction force, a belt of a sheet material employed as the skin at its one end horizontally on one side of the press. The piston rod is horizontally extended from the opposite side of the press to traverse the press and allow the grasping device to grasp the supported end of the belt and then retreated until the grasping device returns to the opposite side of the press, so that the belt is stretched between the stationary and movable dies of the press. By applying heat and pressure to the stretched belt through the movable die, the belt, i.e. the skin, is bonded to the substrate on the stationary die without acquiring wrinkles.
