Abstract
Apparatus for forming a lens pattern for an eyeglass frame includes a guide and a slider mounted on a base. The slider can slide longitudinally on the base. Also included is a mounting device for detachably holding the pattern on the slider. The guide is mounted on the base transversly to the slider. A clamp is included for holding the eyeglass frame against the guide in a continuously adjustable position. Thus the pattern and eyeglass frame are relatively movable in two dimensions.
