MACHINE FOR CONTINUOUS PRODUCTION OF CORRUGATED PIPE Russian patent published in 2020 - IPC B29C48/13 B29C49/30 

FIELD: technological processes.

SUBSTANCE: invention relates to machines for continuous production of corrugated pipe. Machine (1) for continuous production of corrugated pipe includes a plurality of molding assemblies (S), each having a surface and a cavity open on said surface, as well as a first annular track and a second annular track located side by side, to move said molding assemblies (S) along a closed path. Each of said tracks comprises connecting part, along which surfaces of first track forming units contact with surfaces of second track forming units so that corresponding cavities form full matrix for part of corrugated pipe, and determining a connecting plane comprising said connected surfaces, a curved front portion located in front of the connecting portion, and a mating guiding means adapted to direct the molding modules along the track. Response guide means comprises a plate having a lower side, an upper side and a predetermined thickness, wherein on the upper side the first continuous slot is made, and on the lower side – the second slot, with which the molding units (S) are engaged with possibility of sliding.

EFFECT: simplified design of machine for continuous production of corrugated pipe.
