Abstract: PURPOSE: Provided are an apparatus and a method for continuously painting or painting with an alternative mode of controlling the deposition of the liquid, and the eventual coating thickness, in melt-coating processes for the continuous application of coatings of polymeric paints to metal strip. CONSTITUTION: The method of continuously painting one side of a moving substrate metal strip(1) utilizing a thermosetting polymer based paint composition comprises the steps of: pre-heating the strip in a pre-heat furnace(2) to a pre-heat temperature above the glass transition temperature of the paint composition; driving a solid block(8) of the paint composition into collision with the strip at a predetermined block speed to cause liquid paint to be melted from the block and applied to the strip at a precisely controlled deposition rate. The deposit is spread over the surface of the strip by a pressure roll(14) and emerges therefrom as a smooth coat of wet paint. A bead of liquid paint builds up on the strip on the up-stream side of the pressure roll and the block speed may be adjusted in response to the bead size. The emergent strip then travels through a paint curing furnace(5) and a bath(6) to complete the process.

When one of the converters (1, 2 or 3) is out of order, the locomotive is functioning with integral performances, the connection of users to converters being achieved in a suitable manner, by means of threephase contactors (11, 12, 13, 14 and 15). When one of the two converters (4 and 5) is out of order, the locomotive operates with reduced traction performances. The supply of the air compressor and of the traction ventilation systems is achieved with variable voltage and frequency in order to achieve, in case of the compressor, only the provision of the air consumption, while, in case of ventilation, there is achieved the adaptation of the air flow rate to the heating level of the traction equipment.
