UNEVEN CONJOINED TRIPLE WALL DRAINPIPE FOR IMPROVED HARDNESS AND COHESION FORMING DEVICE

摘要

The present invention relates to an unevenness connecting type triple wall sewer molding device to improve hardness and cohesion and, more specifically, relates to a triple wall sewer molding device, wherein after extruding a profile (21) from a second extruder (20) to be cooled, the profile is spirally supplied to a pipe manufacturing device (10) having a drum (24) and a roller (23) at an outer diameter of a guide roller (25), and a triple wall sewer (35) is formed by supplying a molten resin to a gap of the profile (21) with a connection member (32). The present invention is to stably couple a profile and a reinforced connection member for an uneven shape to be coupled to be equal by supplying the reinforced connection member placed in an internal diameter and by supplying an internal diameter of the profile which forms a coupling uneven groove in an upper side of a coupling protrusion of the reinforced connection member.
