| 摘要 |
The invention relates to a method for continuously manufacturing containers made of a flexible material from a single continuous laminar band, or from several continuous laminar bands which will be longitudinally attached to form a single continuous laminar band, which will subsequently be transversely cut. In both cases, in a stage of the production phase a single laminar band, folded over itself along longitudinal fold lines, is obtained, the cross-section of which, open or closed according to the embodiment variant, forms a planar figure in which there is distinguished the upper base of the container, which in a variant of the method comprises a portion of band previously provided with holes and corresponding spouts, collapsed on one side, said single laminar band being susceptible of being driven by means of two drive rollers. |
