PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a pultruded material, capable of improving the homogeneity of a thermosetting resin.SOLUTION: A device 100 for producing a pultruded material comprises a first opening section 112, a second opening section 113, a closing section 114, a tension-applying section 115, an impregnating section, and a mold 140. The first opening section 112 and the second opening section 113 open a bundle of reinforcing fibers 24''' and thereby obtain a bundle of reinforcing fibers 24'. The closing section 114 closes the bundle of opened reinforcing fibers 24' opened by the first and second opening section 112 and 113, and thereby obtains a bundle of reinforcing fibers 24. The tension-applying section 115 applies tension along the direction in which the reinforcing fibers 24 extend to the bundle of reinforcing fibers 24 that pass through the closing section 114. The impregnating section impregnates the bundle of reinforcing fibers 24 with a thermosetting resin 26. The mold 140 pultrudes the bundle of reinforcing fibers 24 that have been impregnated with the thermosetting resin 26.SELECTED DRAWING: Figure 3 【課題】熱硬化性樹脂の均質度を向上させることができる引抜成形材料の製造方法及び引抜成形材料の製造装置を提供すること。【解決手段】引抜成形材料の製造装置１００は、第１開繊部１１２と、第２開繊部１１３と、閉繊部１１４と、張力付加部１１５と、含浸部と、成形型１４０と、を含む。第１開繊部１１２及び第２開繊部１１３は、強化繊維２４´´´の束を開繊して強化繊維２４´の束とする。閉繊部１１４は、第１開繊部１１２及び第２開繊部１１３で開繊した強化繊維２４´の束を閉繊して強化繊維２４の束とする。張力付加部１１５は、閉繊部１１４を通過する強化繊維２４の束に、強化繊維２４の延びる方向に沿って張力をかける。含浸部は、強化繊維２４の束に熱硬化性樹脂２６を含浸させる。成形型１４０は、熱硬化性樹脂２６を含浸させた強化繊維２４の束を、引抜成形する。【選択図】図３
