发明名称 Continuous formation of helical profiles - of resin impregnated filaments, by entrainment between a rotating flighted mandrel and a static threaded collar
摘要 <p>Resin-impregnated filaments are continuously converted into continuous helical profiles by being drawn into a radical clearance between a helical thread on a rotating mandrel and a static threaded collar. Used for mfr. of springs or similar profiles made from thermosetting (e.g. epoxy, phenolic, polyester, polyimide) or thermoplastic resins reinforced with filaments of e.g. glass, carbon silica, metal or 'Kevlar' (RTM - aromatic polyamide).</p>
