Abstract (en)
[origin: ES8400290A1] The invention relates to a method and a machine for manufacturing tubes particularly of paperboard or cardboard by helical winding of a strip or of several strips of paper. This machine comprises a stationary frame supporting a stationary winding mandrel, a system for driving in rotation the tube in formation and a movable frame supporting in particular a device for positioning and guiding the paper strips to form a web, this movable frame being connected to the stationary frame by a coupling device in rotation around a swivel pin. This machine comprises operating means for angular displacement of the said movable frame monitored by a preset value of the angle of winding of the web on the stationary mandrel.
