Abstract

The machine of the invention is essentially a roll- forming machine for the precious metalworking industry or the like, which not only continuously produces a tube from an incoming strip, but also solders the adjacent edges of the strip linearly along a generatrix. The machine of the invention includes a device which ensures a constant distance between the welding electrode and the tube, even when the welding head is raised and lowered for normal maintenance during work. <IMAGE>
