<p>An adhesive blocking system (10), for generating and for fining and polishing eyeglass lenses (L), utilizes a collar (C) which slides over and engages a lens block (B), which lens block (B) is secured to a lens blank (L) by a relatively thick adhesive pad (A), to uniformly transfer pressure from the cylinder machine to the lens blank (L) without deforming the adhesive pad (A), which deformation adversely affects the optics. In this manner, a lens blank (L) is blocked only once for both generating and fining and polishing. In addition, the environmental risks and heating effects of current solder blocking systems are avoided. <IMAGE></p> |
