ABSTRACT:
A feed mechanism for wide format flexible substrates includes a generally cylindrical traction roller having a first axis of rotation, a traction surface and having a length measured parallel to the first axis at least equal to the maximum width of substrate to be used. A generally cylindrical pressure roller has a second axis of rotation, a pressure surface and has a length measured parallel to the second axis at least equal to the maximum width. The pressure roller is deployed with the second axis parallel to the first axis and the pressure surface in rolling contact with the traction surface. A clamping system is configured to apply clamping forces to the pressure roller so as to press the pressure surface against the traction surface while permitting rotation of the pressure roller about the second axis. The clamping system is configured to apply the clamping forces to the pressure roller at at least three locations spaced along the length of the pressure roller.
