Abstract (en)
[origin: WO2013149119A1] A driven layon roller apparatus for a plastic film or sheet winder is driven in rotation by a magnetic coupling. The magnetic coupling allows for torque to be transmitted to the layon roller of the apparatus to rotate the layon roller while adding little or no inertia and imposing little or no radial force to the layon roller as the layon roller moves position relative to the winder.
