Mounting block for mounting a lens in a lens trimming and bevelling machine

摘要

A mounting block for mounting a lens on a trimming and bevelling machine is made of flexible plastic material and adapted to be fixed onto one lens surface by means of a thin film of adhesive material; said block comprises orienting and driving means which cooperate with complementary means mounted on the spindle of the machine. The mounting block is formed with a flexible circular web portion having a conical lower surface which constitutes the lens-contacting surface, and which is provided with a recess in its central portion; the web portion is provided with at least one outwardly extending gripping tab adapted to facilitate the removal of the block from the lens.
