Abstract
A paper rewinding machine includes a rewinding assembly operable to produce coreless retail paper rolls.
Claims64
A method of operating a paper rewinding machine, comprising:
- positioning retail paper on a first bed roller and a second bed roller,
- positioning a rewind arbor in direct contact with the retail paper such that the rewind arbor is supported by the first bed roller and the second bed roller, and
- rotating the first bed roller and the second bed roller so as to rotate the rewind arbor thereby winding retail paper around the rewind arbor so as to produce a coreless retail paper roll, the second bed roller being rotated at a speed that is greater than 3% faster than the speed of the first bed roller.
A method of operating a paper rewinding machine, comprising:
- positioning retail paper on a first bed roller and a second bed roller,
- positioning a rewind arbor in direct contact with the retail paper such that the rewind arbor is supported by the first bed roller and the second bed roller,
- rotating the first bed roller and the second bed roller so as to rotate the rewind arbor thereby winding retail paper around the rewind arbor so as to produce a coreless retail paper roll, and
- rotating a rider roller in contact with the retail paper being wound on the rewind arbor, wherein rotating the rider roller comprises applying a torque on the rider roller that produces a tangential force of at least 1.1 lbs/in on the surface of the retail paper being wound on the rewind arbor.
