An apparatus for production of fiber-reinforced resin strand excelling in durability that is capable of producing a fiber-reinforced resin strand at high production speed without sliding problem. There is provided an apparatus for production of fiber-reinforced resin strand comprising spreader (8) for fibrillation of reinforcing fiber bundle (3) disposed in cross head (5) into which molten resin material (2) is continuously fed from extruder (6); comprising, disposed downstream of exit nozzle (5a) of the cross head (5), twisting rollers (11a,11b) for drawing out fiber-reinforced resin strand (9) composed of a resin impregnated fiber bundle from the exit nozzle (5a) and for strand twisting; and comprising, disposed downstream of the twisting rollers (11a,11b), twist retention rollers (12a,12b) for retaining of the twist of the fiber-reinforced resin strand (9), wherein all the twisting rollers (11a,11b) and twist retention rollers (12a,12b) without exception are made of a metal with uneven surface.

La présente invention concerne un appareil destiné à la production d'un fil de résine renforcé en fibres, présentant une excellente durabilité, qui est capable de produire un fil de résine renforcé en fibres à une vitesse de production élevée sans rencontrer de problèmes de glissement. L'invention porte sur un appareil de production de fil en résine renforcé en fibres qui comprend : une torpille (8) destinée à la fibrillation d'un faisceau de fibres de renfort (3) disposée dans une traverse (5) alimentée constamment en matériau en résine fondue (2) par une extrudeuse (6) ; disposés en aval d'une buse de sortie (5a) de la traverse (5), des rouleaux de torsion (11a, 11b) servant à extraire un fil de résine renforcé en fibres (9) composé d'un faisceau de fibres imprégné de résine provenant de la buse de sortie (5a) et à torsader le fil ; et, disposés en aval des rouleaux de torsion (11a 11b), des rouleaux de conservation de torsion (12a,12b) servant à conserver la torsion du fil de résine renforcé en fibres (9), tous les rouleaux de torsion (11a, 11b) et les rouleaux de conservation de torsion (12a, 12b) sans exception étant en métal et pourvus d'une surface irrégulière.
