Problems solved by technology

Of course, setting up devices of the above type has a significant impact on production costs
[0006] Another disadvantage associated with the use of composite materials is that it is chemically less compatible with thermoplastic and elastomeric polymer materials commonly used in the art, making it diff...

Embodiment Construction

[0049]With reference to the figures, the reference number 1 designates the entire temple, which is suitable for the production and is only schematically indicated in figure 1 A normal pair of glasses 1a. The glasses 1a may be vision correcting glasses, sunglasses, sports glasses, ski glasses, or the like.

[0050] Preferably, the temple 1 is plate-shaped, defining opposite main surfaces S1 and S2 thereon. The first surface S1 is defined as that surface which is visible when the glasses are worn.

[0051] The temple 1 extends mainly in the longitudinal direction, has a longitudinal length L, a height H perpendicular to the length L and parallel to the wearer's head when the wearer puts on the glasses, and a thickness T.

[0052] In order to manufacture different types of glasses, the value of the length L of the glasses legs can be changed appropriately, for example, the legs of glasses for children should have a shorter length L, and the legs of glasses for adults should hav...

Abstract

A arm for spectacles (1, 50) comprises a first portion (11) made of polymer-based composite material reinforced with fibres and at least one film (23, 24) of thermoplastic polymeric material coupled to the first portion (11) as a covering for same.

Description

technical field [0001] The invention relates to a spectacle temple having the features stated in the preamble of main claim 1 . The invention also relates to a method of manufacturing an eyeglass temple having the features stated in the preamble of independent claim 19 . Background technique [0002] Spectacle arms made of thermoplastic or thermosetting polymer materials are known in the related technical field of the present invention. In the search for new technical solutions, functionally and aesthetically it is required in this field to manufacture spectacle arms from composite materials comprising a polymer matrix in which reinforcing fibers are embedded. [0003] In particular, there is a requirement for the production of temples from a composite material in which the reinforcing fibers are of the long fiber type and occupy a high proportion, at least 50% by weight and up to 70%. [0004] This type of material inherently exhibits excellent mechanical properties and a...
