CA 2105476

2105476 9215512 PCTABS00016 An apparatus for precisely advancing film (24) material between two rollers includes a driven roller (22) having a medium hardness rubber surface and a non-driven hard surfaced roller (12) which contacts precision surfaces (13) at either end of the driven roller (22) to accurately control the spacing between the two rollers. The non-driven roller (12) is urged against the driven roller precision surfaces by a spring force (16), and causes the rubber of the driven roller to compress when film material is in an operative position between the roller pair.
