Resiliently faced rolls
Abstract
Abstract ROLLS FOR PRODUCING A CONTROLLED SURFACE FINISH UPON SYNTHETIC THERMOPLASTIC SHEET MATERIAL ARE PREPARED BY USE OF A SUPPORT MEMBER WHICH IS INSERTED INTO A MOLD HAVING AN APERTURE OR CAVITY OF LARGER WIDTH AND A SYNTHETIC PLASTIC RESIN IS INTRODUCED INTO THE SPACING THEREBETWEEN IN THE FORM OF A VISCOUS FLUID TO FORM A COATING ON THE SUPPORT MEMBER. THE COATING OF RESIN IS ORIENTED BY RELATIVE ROTATION OF MOLD AND SUPPORT MEMBER. THE SYNTHETIC PLASTIC IS THEN CURVED AND THE RESULTANT ROLL IS USED AS AT LEAST ONE OF A PAIR OF ROLLS OPERATING UPON THE SURFACE OF THE HEATED THERMOPLASTIC SHEET MATERIAL SO AS TO IMPRESS ITS SURFACE CHARACTERISTICS THEREUPON. ALTHOUGH THE SURFACE OF THE ROLL MAY BE MIRROR-POLISHED, THE ROLLS MOST ADVANTAGEOUSLY HAVE SOLID PARTICLES DISPERSED IN AT LEAST THE SURFACE PORTION OF THE COATING FOR PREPARING A MATTE FINISH ON THE SHEET MATERIAL.
