ABSTRACT:
Method of making pearlescent button blanks by casting and polymerizing a liquid polymerizable resin containing light-reflecting platelets in cavities having the desired form of the button blanks. Pearlescence is imparted to the button blanks by orienting the light-reflecting platelets parallel to the surfaces of the blanks by scuffing a surface of the resin in the cavities during polymerization of the resin. Apparatus for producing buttons by the method of the invention includes a continuous perforated belt and two continuous solid belts that sandwich the perforated belt. The scuffing action for orienting the light-reflecting platelets is produced by sliding the solid belts across the surfaces of the perforated belt.
