PURPOSE:To prevent generation of nap in a strand, by a method wherein a strand widening part comprised by forming a gap between projecting curved surface parts formed by arranging a pair of bar members with the surface parts confronting each other and a molten resin filling part arranged on an introducing port side of a strand of the strand widening part are provided. CONSTITUTION:A strand 1 sent out continuously from a sending out machine 2 is introduced into a strand widening die 6 via a guide 3 under a strained state where tension is applied to the strand 1. Then simultanesouly with widening of the strand the strand is molded into a precursor by a method wherein the strand is compounded with molten resin fed from a barrel part 5, this prepreg precursor is cooled by a cooling bath 8 in succession, after the same is dried by a dryer 9, the same is wound up by a wind-up machine 10. With this construction, since the strand does not come into contact violenty with the bar member of the strand widening part, napping also prevented by friction, surface roughening of the prepreg to be obtained becomes hard to occur and compounding state also between a fiber and the resin becomes favorable. |
