Abstract

A polish or pattern is imparted to the surface of a thermoplastic (e.g. cellulose acetate or polyvinyl chloride) film by applying a softening agent (e.g. water, or a mixture of water and methanol or ethanol) to the surface, which is then brought immediately into engagement with a heated surface having the necessary smoothness or pattern and maintained in engagement until the surface of the film has been substantially rehardened. The polishing or patterned surface may be that of a rotating drum, an arc-shaped surface having a rocker-like motion, or a flat surface performing a stamper movement, and is preferably heated to 180 DEG F., although temperatures between 120 DEG and 220 DEG F. do not lead to significantly different results. The pressure of the plastic against this surface is not critical and may range from 10 to 250 lbs./linear in. width.ALSO:A polish or pattern is imparted to the surface of a thermoplastic (e.g. cellulose acetate or polyvinyl chloride) film or layer by applying a softening agent (e.g. water, or a mixture of water and methanol or ethanol) to the surface which is then brought immediately into engagement with a heated surface having the necessary smoothness or pattern and maintained in engagement until the surface of the film or layer has been substantially rehardened. The polishing or patterned surface may be that of a rotating drum, an arc-shaped surface having a rockerlike motion, or a flat surface performing a stamper movement, and is preferably heated to 180 DEG F. although temperatures between 120 DEG and 220 DEG F. do not lead to significantly different results. The pressure of the plastic against this surface is not critical and good results are obtained with pressures ranging from 10 to 250 lbs./linear in. width. The plastic layer may be on a paper or cloth base, or one surface of a pre-formed plastic film may be polished or patterned in this manner.
