A machine for producing tubes by winding into a spiral strips of ribbon-shaped material (N) on a spindle (1), comprises a winding unit (5) which winds into a spiral two or more overlapping and staggered strips of ribbon-shaped material on the said spindle (1) and causes the tube (T) formed from the said material to advance continuously, and a cutting unit (33) fitted with rotating tube-cutting means (63, 65) and provided with a reciprocating traversing motion along the direction of advance of the tube to cut the said tube into sections of predetermined length during the advance of the tube. The said cutting unit (33) is associated with members (97, 101, 105, 107) for driving the rotating cutting means (63, 65), which impart to the said rotating cutting means (63, 65) a rotary motion derived from the reciprocating traversing motion of the said cutting unit (33). |
