MOLD JAW HALF FOR A CORRUGATOR FOR THE PRODUCTION OF TRANSVERSELY RIBBED TUBES

摘要

The invention concerns a mobile impression half-mould (10) for a corrugator for making pipes with transverse ribs. Said half-mould (10) comprises two sides (12) located spaced apart from each other and a semi-cylindrical base surface (14) linking the two sides (12). Directly mounted forming elements (20, 22; 52, 54; 60, 66; 68 70) bent in the shape of a semicircle which define the outer surface of the pipe with transverse ribs are removably fixed on the base surface (14). Said directly mounted forming elements bent in the shape of a semicircle are removably fixed with fixing elements (34) on the half-mould (10).
