More Information
Summary:A method and apparatus for conveying a web utilizes magnetically coupled first and second rotatable elements. Rotation of one of the rotatable elements causes the simultaneous synchronous rotation of the other rotatable element. Both first and second rotatable elements include a magnetic core, a bonding layer at least partially surrounding the magnetic core, and a wear and abrasion resistant layer surrounding the bonding layer.
