Abstract

1,133,508. Spectacle sideframes; injection moulding. S. POZZI. 15 June, 1966 [16 June, 1965], No. 26797/66. Heading B5A. [Also in Division G2] Spectacle sideframes are made from inner and outer layers of plastics with a reinforcing metal insert therebetween, the insert having a hinge plate to which is fixed pin-means to be embedded in the outer layer. Plastic material is injected into a two-part mould A, B (Figs. 2, 4), to form the inner layer (wearer side) in the lower cavity 2, the upper mould half having a projection 9, forming a seating for the metal insert (11). After moulding, the inner half of the frame is removed from part A and fitted with the metal insert (11) replacing it in a lower mould half (A<SP>1</SP>, Figs. 9, 11, not shown) which is provided with cavities for hinge parts (13), and covering with another upper mould half (B<SP>1</SP>) having a cavity (20) corresponding to the outer half of the sideframe. The inner half is formed having a hole (8, Fig. 5, not shown) for the projection of hinge plate (12), which is connected to the metal insert (11). Mould half A is modified to provide the mould half A<SP>1</SP> by removing plug 6 which forms the hole (8) and replacing it by plug (3<SP>1</SP>, Figs. 9, 11) which forms a cavity (17) to prevent hinge parts (13) from being embedded during the subsequent moulding stage.
