Abstract

Spectacle frames are made by enclosing flat semi-finished thermoplastic frame profiles in a heated split mould which reshapes the profile into three dimensions. Pref. the mould incorporates false lenses which produce a lens-mounting groove in the reshaped blank. Esp. suitable as finishing process for flat blanks produced by sectioning a tubular master profile. Offers rapid prodn. with negligible waste. Partial melt flow may consolidate or orient the moulding material and enhance its stiffness or fatigue resistance.
