A sizing applicator (30) is provided for applying a coating of sizing composition to glass fibers (14). The sizing applicator (30) includes a housing (40) and a roll applicator (70) which is rotatably coupled to the housing (40). The housing (40) has a supply port (46a, 46b) adapted to receive sizing composition from a sizing supply source (80), an exit slot (47) and a passageway (45a, 45b) extending from the supply port (46a, 46b) to the exit slot (47). The passageway (45a, 45b) receives sizing composition from the supply port (46a, 46b) and delivers the sizing composition to the exit slot (47) such that the sizing composition exits the housing (40) and is received on an outer surface (72) of the roll applicator (70). The roll applicator (70) is spaced from the housing (40) such that the housing (40) does not substantially contact the sizing composition once it is received on the roll applicator (70).

L'invention concerne un applicateur de colle (30) pour appliquer une couche de composition d'encollage sur des fibres de verre (14). Ledit applicateur (30) présente un boîtier (40) et un applicateur à rouleau (70) relié rotatif au boîtier (40). Le boîtier (40) présente un orifice d'alimentation (46a, 46b) conçu pour recevoir la composition d'encollage en provenance d'une source d'alimentation en colle (80), une fente de sortie (47) et un passage (45a, 45b) s'étendant depuis l'orifice d'alimentation (46a, 46b) jusqu'à la fente de sortie (47). Le passage (45a, 45b) reçoit la composition d'encollage en provenance de l'orifice d'alimentation (46a, 46b) et l'envoie dans la fente de sortie (47) de sorte qu'elle sorte du boîtier (40) et soit reçue sur une surface extérieure (72) de l'applicateur à rouleau (70). L'applicateur à rouleau (70) est à une certaine distance du boîtier (40) de sorte que ce dernier (40) n'entre sensiblement pas en contact avec la composition d'encollage une fois que celle-ci se trouve sur l'applicateur à rouleau (70).
