Abstract: Procedure to form a permanent tip in polymer, formed directly in correspondence with the end portion of a support arm in metallic wire for spectacles, in which a work cycle foresees at least the following phases: (a) preparation of a bath with a liquid solution which includes a polymer; (b) immersion in the bath of at least the end portion and, in the first case, of a support arm in metallic wire for spectacles without a coating; (c) removal of the support arm in metallic wire from the bath, according to a pre-determined speed; (d) movement of the support arm towards a solidification station for the solidification of the portion immersed in the bath; (e) if required, repetition of at least phases (b), (c) and (d). The support with the end coated by the polymer tip form a single piece with, at one end, a progressive reduction for the thickness of the tip which has been formed before the end of the support arm, and if required, with an enlargement of the end of the tip in the form of a droplet.

Abstract: Spectacles assembly with a bow-shaped frame and support clip for an interchangeable frontal lens holder. The assembly includes: a bow with arms, for the support of the frontal lens holder; a frontal lens holder made out of profiled material, where the said material goes around at least a part of the outer edge of the lens; and a device with a flexible movement, used to join the frontal lens holder to the bow. The flexible device is formed in correspondence with the connection bridge between the two arch-shaped sections which make up the bow. The frontal closed-ring lens holder has a connection bridge between the peripheral support of the lenses, with the bridge being hooked by a clip which is formed monolithically by the bow.
