ABSTRACT:
Apparatus for manufacturing flexible tubes comprising a skirt and a head provided with a neck and a shoulder linking the neck to the skirt, the apparatus having a first zone devoted to manufacturing the skirts, a second zone devoted to manufacturing the flexible tubes, a third zone devoted to finishing the flexible tubes thus produced, a first transfer device transferring the skirts in continuous motion from the first zone to the second zone, and a second transfer device transferring, in continuous motion synchronized with the former, the tubes from the second zone to the third zone. The second zone has a third transfer device for transferring the punches in continuous motion synchronized with that of the first transfer device and with that of the second transfer device, loading device for loading the skirts on the punches associated with the synchronized movement of said first and third transfer devices, and unloading devices for freeing the punches from the tubes covering them for associated with the synchronized movement of the second and third transfer devices.
