This process will require both the forming of the raw material and feeding of the formed material into a hot end. I think I may have to power these two processes individually.

The power requirement for the forming process will pull the ribbon of plastic, both creating the initial ribbon and pushing it into the entubulator (made up word used to describe the equipment used form a tube from the flat ribbon).

For the feeding of the formed tube, it may be useful to consider using a separate, traditional friction-based filament driver.

Both the forming and feeding will require one NEMA stepper each, but both motors can run off the same power and input as the feed rate will be determined by the gcode.
