ABSTRACT:
A method and apparatus for applying a strip to the planar contour-prepared edge of a lens. The beginning of an endless strip is connected to the edge of a lens. A transverse perforation is introduced into the strip at a distance from the strip beginning that corresponds to the circumference of the lens. The lens is then rotated, and the strip is restrained, at a location thereof behind the perforation when viewed in the direction of movement of the strip, in such a way that the strip tears at the perforation to form a new strip beginning for the next lens. This new strip beginning is pressed against, and connected to, the edge of the next lens. A register is provided for determining the circumference of a lens.
