METHOD AND APPARATUS FOR THE PRODUCTION OF WOUND CYLINDRICAL BODIES OF RESIN- IMPREGNATED GLASS FIBER WITH A SANDWICH CORE Abstract of the Disclosure Process and apparatus for forming cylindrical sand- wich constructions of glass fiber impregnated with synthetic resin, in which the core between the inner and outer shells is a spiral-wound corrugated strip of glass fiber impregnated with synthetic resin such as polyester resin. A strip of glass fibers impregnated with synthetic resin is fed between a pair of coacting endless belts whose adjacent runs are provided with interfingering projections to corrugate the strip. Retainer filaments can be laid over the spiral-wound corrugated strip to hold the same in place until the outer shell of glass fiber impregnated with resin is spiral wound thereover. The corrugating unit and its glass fiber supply and the supply of the retainer filaments, are all mounted for movement as a unit parallel to the axis of the cylindrical member. -1-
