There are a bunch of devices sold to attach poly to pipe/tube for roll ups. For the quick and cheap get some pvc or black plastic pipe and cut chunks length wise in half. Keeping your roll tube and plastic as straight as possible place a section of half pipe on top of the poly and attach with self drill scrers.
A 6 inch clip every 4 feet should be enough,if you can arrange for the poly to have a few extra turns around the roll tube is best but not usual. On hort houses we used a skirt along the lower part of the greenhouse side (+- 30" high) to act as a seal when the side vent is closed, and as a barrier for wind blowing in on the plants in the lower part of the house. For livestock houses the skirt was more optional but on cool breezy days the floor temp difference was striking.

If you dont mind risking hands, wrists, and jaw bones attach a tee to the end of the roll tube, slide a 2 - 3 foot piece of steel rod through the tee making a handle for rolling the tube, when it is as high as you want it slide a long chunk of pipr over the rod and let the other end rest on the ground preventing
unrolling.
 
If you are awash in case get a gearbox and guide tubes for safely rolling the poly side.
