Abstract (en)
[origin: WO2020030466A1] The invention relates to a system (20) for spraying products onto glass fibres (3), designed to spray at least one sizing composition (121) and an anti-dust agent (221) onto the glass fibres. The spraying system comprises two separate annular spraying elements which are successively arranged on the path of the glass fibres, the two spraying elements comprising a first annular element (120) for spraying the sizing composition and a second annular element (220) for spraying the anti-dust agent, each one embodied by at least one specific annular crown surrounding the glass fibres. The second annular element (220) for spraying the anti-dust agent is arranged downstream of the first annular element (120) for spraying the sizing composition in relation to the path of the glass fibres (3).
