Abstract
The surface texture of plastic film cast against chill rolls may be accurately predicted from the roll surface texture while mounted in a roll finishing machine by correlating a glossmeter measurement of the roll surface to an experimentally determined functional relation between similar rolls and corresponding film product. Means are provided on the glossmeter test base to assure accurate orientation of the instrument relative to the cylindrical surface and axis of the test subject.
