To provide an apparatus and method for producing a prepreg sheet with uniform quality, capable of imparting a resin uniformly to each strengthened fiber bundle.SOLUTION: A plurality of drawn-out strengthened fiber bundles are divided into fiber bundle units made of one or more strengthened fiber bundles by a thread guide control mechanism. A specified quantity of resin is independently and continuously imparted to the strengthened fiber bundle units passing through a fiber bundle unit passage area by a resin imparting mechanism disposed in the vicinity of the thread guide control mechanism.SELECTED DRAWING: Figure 1 【課題】本発明はプリプレグシートの製造に関して、強化繊維束ごとに均一に樹脂が付与され、品質が均一であるプリプレグシートを製造する装置および方法を提供する。【解決手段】引き出された複数本の強化繊維束が糸道制御機構で１本ないしはそれ以上の強化繊維束からなる繊維束単位に分割され、糸道制御機構近傍にある樹脂付与機構によって繊維束単位通過領域を通過する強化繊維束単位に対して、独立して連続的に所定量の樹脂を付与する。【選択図】図１
