Abstract

Framgangsmåte for strengsprøyting av hulprofiler, rør eller liknende av polymert materiale med en sjiktvis sammensatt vegg, med et yttersjikt (7) av massivt polymennateriale, et mellomsjikt (6) av på annen måte strukturert polymermateriale og et dekkende innersjikt (92) av massivt polymermateriale ved bruk av en form hvor sjiktene l langsgående fuger ved tilvirkningen. Formålet er å redusere den uheldige innvirkningen fra fugene på styrken. Dette formålet oppnås ved at i det minste det massive polymermateriale (91) for innersjiktet (92) tilføres til mellomsjiktet (6) hhv. til kombinasjonen av mellomsjiktet (6) og yttersjiktet (7) først i den fremre delen (85) av formen og på dette stedet forbindes, med mellomsjiktets (6) innside ved strengsprøyting-sveising, og at de langsgående fugene i sjiktene som dannes ved strengsprøytingen plasseres i ulike stillinger i omkretsretningen for ulike sjikt. Det er også beskrevet en anordning for å gjennomføre denne framgnagsmåten.Method of string spraying hollow profiles, tubes or the like of polymeric material with a layered composite wall, having an outer layer (7) of solid polymeric material, an intermediate layer (6) of otherwise structured polymeric material and a covering inner layer (92) of solid polymeric material use of a mold in which the layers of longitudinal joints during manufacture. The purpose is to reduce the adverse impact of the joints on the strength. This object is achieved by supplying at least the solid polymeric material (91) for the inner layer (92) to the intermediate layer (6) respectively. to the combination of the intermediate layer (6) and the outer layer (7) are first connected in the forward part (85) of the mold and at this location, with the inside of the intermediate layer (6) by string spray welding, and that the longitudinal joints of the layers formed by the spray injection placed in different positions in the circumferential direction for different layers. A device is also described for carrying out this method of operation.
