METHOD OF MANUFACTURE OF THE MULTI-CHAMBER PIPE Russian patent published in 2007 - IPC B29D23/00 B65D35/22 B29C69/00 

FIELD: chemical industry; method of manufacture of the multi-chamber pipes.

SUBSTANCE: the invention is pertaining to the method of manufacture of the multi-chamber pipe with at least two chambers and one tubular head with the locking outlets corresponding to the number of the chambers. The presented method provides that they separately manufacture at least two located in parallel to each other tubular components forming at overlaying the common rounded external perimeter. The tubular components at least in two places are supplied with the axial incision lines. Tubular components are forced on the separate number of the mandrels corresponding to the number of the desirable chambers. The mandrels with the tubular components bring together and jointly bring to the position of molding and mold the portions of the plastics material for production of the tubular head with partitions at the simultaneous coupling of the tubular head with the ends of the tubular components. The adjacent to each other sections of the tubular components at least partially are bound to each other in the longitudinal direction. The invention ensures simplification and reduction of the cost of manufacture of the multi-chamber pipe.

EFFECT: the invention ensures simplification and reduction of the cost of the multi-chamber pipe manufacture.
