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 traveling 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).
Machine à fabriquer les tubes par enroulement en spirale autour d'une broche d'un matériau en forme de ruban (N). Ladite machine comprend un enrouleur (5) qui enroule en continu en spirale autour de ladite broche (1) deux ou plusieurs bandes dudit matériau se recouvrant tout en étant décalées et qui amène le tube (T) ainsi formé à progresser en continu tandis qu'une tronçonneuse (33) munie de moyens rotatifs de coupe (63, 65) du tube (T) et animée d'un mouvement transversal alternatif par rapport au sens d'avancement du tube découpe celui-ci en tronçons de longueur donnée lors de sa progression. Ladite tronçonneuse (33) est associée à des éléments (97, 101, 195, 107) entraînant les moyens rotatifs de coupe (63, 65) et leur conférant un mouvement rotatif dérivant du mouvement transversal alternatif de la tronçonneuse (33).
