Abstract

The system is for producing helically-wound lock-seam tubing (15) from a metal strip (12) having longitudinal edge portions (16a, 16b). It included the steps of feeding the strip to a forming head (14), and forming the strip into helical shape in the forming head, whereby the edge portions of the helically formed strip are brought into engagement with each other. This is followed by clinching the engaging edge portions of the strip to form a helically-wound lock seam (25) on a tube formed in the forming head. The helically-wound lock-seam tube is fed out of the forming head, and, before the forming head, lubricant is supplied locally on that side of the strip which forms the outside of the tube, the lubricant being supplied over only a limited portion of the width of the strip.
