ARTICLE FOR SUPPORTING SLENDER PROCESSED GOOD WITH FIRST AND SECOND SLENDER FLAT AND APPROXIMATELY PARALLEL SURFACE

摘要

A workpiece carrier has a support bar centrally supported at one end of a stem portion. The stem is carried at its opposite end on a base. Columns are interposed between the ends of the support bar and the base. Heat is applied to the columns, preferably by resistive heating elements, to heat them and cause their thermal expansion, causing the support bar ends to be bent away from the base. A relatively flexible workpiece which has been bonded to the support arms on a surface facing away from the base will undergo the same bend.
