摘要:Apparatus and methods for making spectacle lens patterns are disclosed. Theapparatus uses a router (or similar) bit, a spring-loaded, adjustable follower, and anexisting lens (or pre-cut model) to produce patterned blanks either identically orproportionally sized to corresponding template or model lenses. The router bit rotatesrapidly about its longitudinal axis as it penetrates the slowly rotating blank, producing asmooth pattern after as few as one rotation of the blank. The cover of the inventionmaintains the follower and cutting bit in suitable (albeit adjustable) alignment whilepermitting easy access to the interior of the device for inserting and removing both thelens and blank. A chute, pouch, or chip containment cavity may also be included to receivethe by-products of the cutting operation for easy disposal.
