Patent ID: 7913641

Claim:
An apparatus for coating a cylinder with a plastic composition comprising: supporting means for horizontally mounting a cylinder for rotation about its axis of rotation; a coating unit disposed on one side of the cylinder for selectively applying a layer of heat-hardenable plastic composition onto the surface of the cylinder; driving means for rotating the cylinder in a direction to cause its peripheral surface to move past said coating unit; heating means for applying radiant heat to said cylinder throughout its length as said cylinder is rotated, said heating means being disposed in a movable hood part adapted to be moved on top of the cylinder for applying heat thereto or away from the cylinder to allow mounting or dismounting of the cylinder on or from the supporting means, said movable hood part forming, when moved on top of supporting means, an interior space enclosing the cylinder; and an aspiration system with aspiration inlets provided on said movable hood part for aspirating fumes out of the interior space of the movable hood part, wherein said movable hood part includes a hood body and a window panel mounted on a front side of said hood body to allow a human operator to monitor deposition of the plastic composition onto the surface of the cylinder, said hood body and window panel being constructed in such a manner that, when the movable hood part is moved on top of the cylinder, the window panel lies above the position where the coating unit cooperates with the cylinder during coating.
