Abstract
Apparatus is provided for the continuous production of tubing from steel strip. The formed tubing is continuously advanced along a straight-line path through polishing and buffing units to provide a smooth lustrous finish to the tubing, and through a coating chamber in which the tubing is coated with a polymer coating to prevent tarnishing of the lustrous polished surface. The finished tubing has a surface which is suitble for decorative applications such as furniture or the like.
