The present invention relates to a method and to a device for manufacturing parts made from resin and reinforcing fibers by winding. Molding means including a plurality of female forms corresponding each to a print of the part to be manufactured are produced. The forms are arranged one after the other, substantially helically, so as to make a continuous groove, then said groove is filled by winding with fibers coated with a polymerizable resin by rotating the prints round the axis of the helix.

A method for manufacturing articles made from resin and reinforcing fibers, wherein said articles are cut from an elongated main blank at sections thereof having a substantially constant arcuate surfaces, the method comprising the following steps: providing molding means (5) including a plurality of female forms (1, 1a, 1b, 1c) corresponding to the shapes of the parts being manufactured, arranging said forms sequentially to form a substantially continuous groove formed as a single helix about the axis (4) of the molding means, wherein the groove is defined by non-parallel, radially extending, spaced apart stationary walls to provide sections of the main blank which when severed from the main blank by cuts in a direction transverse thereto form a plurality articles with non-parallel side surfaces; filling said groove by winding fibers coated with a polymerizable resin on the molding means by rotating said molding means in one direction around the axis (4) of the helix while advancing the fibers in only one axial direction with respect to the groove to form helically the elongated main blank in the groove into a molded helical blank; and severing the molded helical blank at selected locations to form the plurality of individual articles having shapes complementing the female forms. A device for manufacturing a plurality of articles made from resin and reinforcing fibers, wherein said articles are cut from a single elongated main blank at sections thereof having a substantially constant arcuate surface, the device comprising molding means including a plurality of female forms corresponding in shape to the shapes of the articles, said forms being arranged sequentially substantially helically, so that said shapes when joined end to end make a single substantially continuous helical groove, wherein the groove is defined by non-parallel, radially extending, spaced apart stationary walls to provide the sections of the main blank which are severed from the main blank by cuts in a direction transverse thereto to form articles with non-parallel side surfaces end wherein the device further includes a cutter for severing the main blank.
