<p>Process for producing prism-shaped containers without side-projections and with level gable-shaped surfaces as the closure ends, using a continuously fed tube of flexible material filled with a liquid substance, whereby the lateral regions (2, 4, 2', 4') connected to the transverse sealing strips (5, 5') are slid inside the tube (1, 1') before the actuation of the transverse flattening mechanisms, in this way the formation of unattractive projecting side-pieces on the closure surfaces is avoided.</p> |
