Metodo per la fabbricazione di componenti di montature per occhiali e componenti di montature realizzati con detto metodo

摘要

A method is described for manufacturing spectacle frame components, such as a front frame (1) of the frame or a side arm (2) of a frame or part of the front frame or the side arm, comprising the following successive phases: preparing a cellulose acetate slab (11) having a preselected, defined thickness between opposite faces (11a, 11b) of the slab, placing the slab (11) in an over-injection mould, over-injecting elastomer over at least one of the faces of the slab (11) over at least part of the surface extent of that face to produce a slab-shaped, multilayer semifinished product (13), removing the semifinished product (13) from the mould, shaping the semifinished product (13) by cutting and/or milling to produce the preselected final shape of the component, the slab-shaped structure of the component thus made being formed of at least two layers, respectively a layer of cellulose acetate and a layer of elastomer.
