Method and apparatus for filament winding on a corrugated form to produce a cylindrical corrugated glass fiber part

摘要

The method of filament winding on a corrugated form to thereby form a cylindrical corrugated part includes the steps of CAUSING RELATIVE MOTION BETWEEN SAID FORM AND A GLASS FIBER APPLICATOR, WRAPPING A GLASS FIBER BAND WITH A RESIN COATING THEREON ON SAID FORM IN A SPIRAL PATTERN WITHOUT BRIDGING OVER SAID CORRUGATIONS IN SAID FORM, PERMITTING SAID GLASS FIBER TO HARDEN ON SAID FORM THEREBY FORMING SAID CORRUGATED PART, AND REMOVING SAID HARDENED PART FROM SAID FORM AFTER A PREDETERMINED PERIOD OF TIME.
