Abstract
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.
Claims21
A driven layon roller apparatus for winders, the apparatus comprising:
- a frame;
- a central shaft supported on the frame;
- a layon roller mounted for rotation on the central shaft;
- a magnetic first coupling piece adjacent the layon roller, the first coupling piece being rotatable relative to the frame;
- and,
- a magnetic second coupling piece mounted stationary on the layon roller, the second coupling piece being adjacent the first coupling piece wherein magnetic flux between the first coupling piece and the second coupling piece causes the second coupling piece and the layon roller to rotate in response to rotation of the first coupling piece.

A driven layon roller apparatus for winders, the apparatus comprising:
- a frame;
- a central shaft mounted on the frame and supported by the frame;
- a layon roller mounted for rotation on the central shaft, the layon roller having an axis of rotation that defines mutually perpendicular axial and radial directions relative to the layon roller;
- a magnetic first coupling piece mounted on the frame for rotation of the first coupling piece relative to the frame and around the layon roller axis of rotation;
- a drive transmission operatively connected to the first coupling piece for rotating the first coupling piece;
- and,
- a magnetic second coupling piece connected to the layon roller for rotation of the second coupling piece with the layon roller around the layon roller axis of rotation, the second coupling piece being adjacent the first coupling piece wherein magnetic flux between the first coupling piece and the second coupling piece causes the second coupling piece and the layon roller to rotate in response to rotation of the first coupling piece.
