Abstract
The fiber-coating apparatus comprises an injector having a tubular grid mounted between two dies between which the fiber travels on the axis of the grid, which grid filled with resin that penetrates therein via holes distributed through its wall. The wall of outside diameter d is situated at a minimum distance from the wall of diameter D which surrounds it in the injector, such that the ratio D /d is not less than 1.35 and the difference D −d is not less than 4 millimeters. The holes through the wall have a minimum diameter of 0.50 mm and a minimum density of 0.20 holes per mm . The height of the grid lies in the range 5 mm to 50 mm, and the difference between the outside and inside diameters of the cylindrical wall of the grid is not greater than 10 mm, with a minimum inside diameter of 5 mm.
