Abstract: A process for mounting an elastic hinge on eyeglass frames, for coupling a first pivot element, which comprises an elastic carriage provided with a head portion having a first hole, with a second pivot element comprising two shoulders provided with second holes. The head portion of the first pivot element comprises a tilted slide surface adjacent to the first hole. The process envisages to insert the head portion in a slit between the shoulders of the second pivot element to place in succession their holes offset from each other, and then engaging a hinge pin in the holes, so that the free end of the hinge pin acts in abutment against the slide surface of the head portion, in order to force the carriage to slide until the first hole of the first pivot element is aligned with the second holes of the second pivot element.

Abstract: Method for the assembly of elastic hinges on an eyeglass frame, wherein each elastic hinge has a first and a second articulation elements hinged around a hinging axis. The method provides for a first step of inserting the first articulation element in a first seat of a temple and, subsequently, a second step of inserting the second articulation element in a second seat of an end piece of the eyeglasses. In the first insertion step, the second articulation element is placed perpendicular to the first articulation element with the hinging axis placed at a first distance from the temple. Before the second insertion step, a tensioning step is provided in which the second articulation element is rotated up to being arranged parallel to the first articulation element, bringing the hinging axis to a second distance from the temple that is greater than the first distance.
