Making rollers for paper

I'm building a paper cutter that will feed paper from rolls up to 5
feet wide. I need to make motorized rollers that can feed the paper
in very precise measurements.

I was thinking of making the rollers from 1 plastic pipe that would
turn around a copepr pipe, and make the motorized roller from a
threaded rod with rubber washers or something like that on it.

Do you think this would work well? Does anyone have any idea how to
make better rollers?

Thanks

    McMaster-Carr -- www.mcmaster.com -- has a good selection of roller
    bearings, shafts, couplers, and other necessary hardware.

    5 ft long rollers will bend like rubberbands. typically they are
    either solid or large diameter and hollow. a larger rubber coating
    is applied often and then cut to be round.

    It sounds like a pretty hefty project and some research is in order.

    If you can support the rollers at different points across, then you
    can use lighter weight materials.

    Paper is abrasive and dusty so considder future replacement options
    when putting it together.

    as far as controlling the paper, what speed are you trying to
    achieve ?

    can you stop the paper to cut it ?

    cutting it on the fly will be even more demanding but the machines
    that do that stuff are neat to watch.

    Printing presses use rollers like that all the time. If it's a one-off,
    locate some parts from a scrapped printing press.
