<p>The present invention provides an impregnation system suitable for impregnating filaments continuously with an impregnating substance, said system may comprise an impregnation assembly comprising (a) at least one axial passageway for the filaments having an entrance end and an exit end and (b) at least one passageway for the impregnating substance having at least one inlet for the impregnating substance and at least two outlets for the impregnating substance leading into the passageway for the filaments via the outlets for the impregnating substance, wherein the passageway for the filaments has an oblong cross-section at the outlet point for the impregnating substance, and the at least two outlets for the impregnating substance have an oblong cross-section, and are disposed essentially opposite to each other, at the opposite widths of the passageway for the filaments. Thus, the present invention proposes an in-line system for manufacturing continuous fiber reinforced thermoplastic structure which comprises a simple device to provide strands in spread filaments form without using high friction or tension on the strand or filaments so as to ease the impregnation step and to allow higher line speeds and lower cycle times.</p> |
