Abstract: Disclosed is a device for removing mattes from the surface of a liquid metal bath inside a duct of a line for continuously coating a metal strip having first and second faces, the first face being intended to come into contact with a bottom roller, comprising a compartment via which the liquid metal inside the duct is replenished by being drawn off by a pump to which the compartment is connected, characterized in that the compartment is capable of being removed by disassembly means without the metal strip needing to be cut.

Abstract: A printing unit including: a frame; a first print station (6) having a first blanket cylinder (10) and a first plate cylinder (12); an impression cylinder (14); and a first spacer device (100) designed to move the cylinders relative to each other between a printing configuration in which the plate cylinder (12) is in contact with the associated blanket cylinder (10) and a non-printing configuration in which the plate cylinder (12) is moved away from the blanket cylinder (10) and the blanket cylinder (10) is moved away from the impression cylinder (14). The printing unit also includes a second spacer device (200) designed to regulate the distance between the cylindrical surfaces of the first blanket cylinder (10) and the impression cylinder (14), said second spacer device (200) including means for moving the impression cylinder (14) radially relative to the first blanket cylinder (10) and relative to the frame.
