ABSTRACT:
As a substitute for brazing conventionally employed for attaching curved pad holders to rims of an eyeglass-frame, casting is used for formation of an eyeglass-frame including, in one body with its rims, straight pad holders which should thereafter be bend to a required configuration. Conventional troubles arising from use of brazing are fully removed.
