Abstract
The present invention provides a lubricant coat forming apparatus for forming a dry coat of water dry type lubricant on the surface of each of cold plastic working materials. The apparatus includes a heating unit for heating the cold plastic working materials to a predetermined temperature, a lubricant applicator for applying the lubricant on the surfaces of the cold plastic working materials heated at the heating unit, and a drying unit for drying the lubricant applied on the surfaces of the cold plastic working materials by applying cooling air stream to them. The cooling air stream has a temperature lower than that of the cold plastic working materials heated by the heating unit.
