Abstract

The process improves the appearance of the surfaces of metal tubes widened into a cone to allow nesting together. Immediately after the widening operation, they are coated with transparent varnish, or a lubricant is sprayed onto their surfaces. They are afterwards dried if necessary. After varnishing and drying the tube can be subjected to a polishing or glazing operation. The system avoids spoiling the surface of the tubes due to the varnish cracking etc.
