A machine for producing tubes by winding into a spiral two or more overlapping and staggered strips of a ribbon-shaped material on a spindle, having a winding unit which winds into a spiral two or more overlapping and staggered strips of a ribbon-shaped material on the spindle and causes the tube formed from the material to advance continuously, and a cutting unit fitted with rotating tube cutters and provided with a reciprocating motion along the direction of advance of the tube to cut the tube into sections of predetermined length during the advance of the tube. The cutting unit is associated with members for driving the rotating cutters, which impart to the rotating cutters a rotary motion derived from the reciprocating motion of the cutting unit.
