ABSTRACT:
A holder and carrier for a plurality of holders is constructed to engage the band-like edge of a thin disk-shaped workpiece. The holder comprises a plurality of spring bars which are connected at corners to form a polygon which engages the outer edge of the workpiece. Each corner is held within a slot shaped receptacle which in turn is defined in a frame for holding the workpiece with minimum shadowing and minimum danger of scratches, warping of other disadvantageous effects.
