Abstract
An apparatus for manufacturing tow prepreg includes: a spreading roller which adjusts an incident angle of supplied fiber; and two or more coating rollers including a first roller and a second roller which rotate while having a gap between the first roller and the second roller, in which the fiber supplied from the spreading roller passes through the gap between the first roller and the second roller to be coated with resin. The incident angle of the fiber supplied for immersing the resin is adjusted to adjust tension applied to the fiber supplied to a coating roller, such that the quantity of the resin of the tow prepreg can be controlled more precisely.
