Pulling each roving separately through an orifice is an alternative way for wiping the resin-impregnated rovings in the filament winding process.

Pulling each roving separately through an orifice is an alternative way for wiping the resin-impregnated rovings in the filament winding process. Correct Answer True

This technique provides better control of resin content compared to the wiping device technique. But the probability of the fiber breakage increases and it becomes difficult to rethread the broken roving line through its orifice.
