ABSTRACT:
A method and apparatus for precisely advancing film material between two rollers includes a driven roller having a medium hardness rubber surface and a non-driven hard surfaced roller which contacts precision surfaces at either end of the driven roller to accurately control the spacing between the two rollers. The non-driven roller is urged against the driven roller precision surfaces by a spring force, and causes the rubber of the driven roller to compress when film material is in an operative position between the roller pair.
