<p>The subject of this invention is a new device for sustaining and perfectly positioning the side-piece of glasses during the shearing phase, on the side for hinging to the front. The innovative characteristic of the invention is that it is composed of an element A, housing and translating the side-piece to be sheared up to the cutting element C, with a pressure element B for securing the side-pieces themselves, the element A being constituted by a horizontal drum 11 on which an interchangeable ring 17 is applied, provided with apertures 18, to be rotated clockwise, until it meets a belt 30 which, by means of appropriate pulleys 31, 32 and 33 is tensioned adequately to accompany and block the side-pieces at the cutting point C. <IMAGE></p> |
