Abstract
An eyeglass frame is produced from a plastic workpiece panel of elongated outer periphery having two lens-holding apertures, each aperture having a groove about its perimeter for receiving the lens of the eyeglass. The workpiece is placed upon a holder having two slidably adjustable chucks, each chuck having impingement structure which controllably engages the perimeter of the aperture. The impingement structure is driven in radially divergent directions toward the perimeter by pressure applied from balls housed within the chuck.
