Abstract
A high-precision, metal-faced, calendar roll which can be readily reconditioned by thermal means. The calendar roll has a surface which is advantageously formed of that class of nickel-titanium alloys having thermally-responsive shape memory properties. The calendar roll is particularly useful in avoiding time consuming repair and undesirably prolonged runs in making high quality magnetic tape.
