Abstract: A substrate capable of being wound is transported to a substrate carrier and wound onto the latter. For that purpose the substrate is first held in a defined storage position. With the substrate in that storage position the substrate carrier is moved into a threading position and brought into engagement with the substrate. The substrate is then automatically threaded around the substrate carrier. When the threading operation is complete, the substrate carrier is moved into a winding position in which the substrate is wound onto the substrate carrier. The rate of feed at which the substrate is transported by a motor to the substrate carrier is regulatable. The substrate carrier is motor-driven in a controllable manner, at a uniform torque and in dependence on the feed rate at which the substrate is transported to the substrate carrier.

Abstract: A board to be coated is conveyed by means of first transport means in the form of a roller conveyor to a curtain coating device. The latter comprises second transport means in the form of two conveyor belts, each of which runs round an associated straightening bar in the direction of transport of the board. The straightening bars are movable and as they move towards one another they align the boards at the side edges thereof in such a manner that the side edges extend approximately parallel to the direction of transport of the board. Conical rollers are connected to the straightening bars. During alignment, that is to say, when the straightening bars are moved towards one another, the board to be coated is at the same time lifted from the roller conveyor by means of the conical rollers and conveyed via the surfaces of the conical rollers to the conveyor belts. The latter engage laterally at the board edges and transport the board through a pouring curtain for the purpose of coating.
