<p>In a method and apparatus for controlling at least one of the position, the orientation and the configuration of a material web during movement of the web in a predetermined direction, a magnetically responsive material is applied to the material web and the web is exposed to at least one magnetic field during movement of the web in the predetermined direction. The at least one magnetic field attracts or repels the magnetically responsive material applied to the material web to thereby control at least one of the position, the orientation and the configuration of the web during movement of the web in the predetermined direction. In one embodiment, the magnetic field is generated by a magnetic field generator operable to generate a magnetic field in magnetically responsive communication with the material web upon movement of the web in the predetermined direction.</p> |
