In the first station, continuous fiberglass roving is dispensed from center-pull packages that sit on shelves called creels. The roving is guided through porcelain eyelets that eliminate static build-up and degradation of the glass, or fuzzing. The roving then passes through a carding index that orients the fibers prior to entering the resin bath. For the product shown here, only continuous glass fiber rovings are used.
Other reinforcements such as mat, knitted, woven and braided fabrics, veils, carbon fiber tows, etc. are routinely used and are dispensed tangentially from the rolls.
