The invention relates to a machine for manufacturing tubes, intended, in particular, for making up packaging boxes, by rolling up rectangular sheets F on themselves and linking their end edges which have come opposite each other by gluing, comprising, in a frame - a cylindrical mandrel 1 for rolling up the sheets into tubes, mounted so as to overhang, coupled to a mechanism for rotational driving in successive complete revolutions and equipped with suction orifices 12 ensuring the momentary holding of the front edge of the sheets against a specific generatrix G of its periphery, - a device 20, 30 for supplying sheets, which present these to the mandrel, - a device 40 for applying glue to the end edges of the sheets rolled up on the mandrel 1, - a device with presser roller 51 for applying the glue-laden edges of the sheets against each other, - and a ring 18 for ejecting the completed tubes. <IMAGE> |
