Tow prepreg manufacturing apparatus and tow prepreg manufacturing method

摘要

PROBLEM TO BE SOLVED: To suppress variation in resin content of tow prepreg. SOLUTION: A discharge nozzle 22 having a rectangular discharge port in which a resin is applied to a conveyed reinforced fiber bundle F and a length in a longitudinal direction thereof is longer than a yarn width of the reinforced fiber bundle F, and the discharge nozzle 22. By changing the angle of the width detection sensor 40, which is arranged on the upstream side and outputs a width detection signal based on the yarn width of the reinforcing fiber bundle F, and the discharge port with respect to the yarn width direction of the reinforcing fiber bundle F, An angle adjustment unit that adjusts the length of the resin discharged from the discharge port in the yarn width direction, and the length of the resin discharged from the discharge port in the yarn width direction based on the width detection signal, An angle controller C is provided to control the drive of the angle adjuster so as to approach the yarn width of the reinforcing fiber bundle F supplied to the discharge nozzle 22.
