Abstract
PROCEDURE AND CORRESPONDING DEVICES, TO CONSTITUTE TUBE WITH HELICOIDAL SEWING, according to which procedure, complementary tabs are produced at the longitudinal edges of a continuous strip or strap, capable of being coupled together; proceeding next to spirally wind the continuous strip, so as to verify the crimping of the flanges, which are projected helically along the entire length of the structural tube constituted; then the folding of the tabs on the tube is carried out, by crushing them, until the verified seaming guarantees the tightness of the tube.
