ABSTRACT:
Mechanism for angularly adjusting a web-supporting steering roller of a web tracking apparatus about its steering axis in response to lateral movement of the supported web relative to the steering roller. In the web tracking apparatus, the web-supporting steering roller is mounted for rotation about its longitudinal axis and angular adjustment about a steering axis perpendicular to such longitudinal axis. The mechanism for angularly adjusting the steering roller comprises a lever assembly, for example, coupled to the steering roller for rotating such roller about the steering axis. Lateral movement of the web relative to the steering roller is sensed. A member, associated with the lever assembly and responsive to the sensing of lateral web movement, moves the lever assembly to rotate said steering roller for angular adjustment about the steering axis an amount corresponding to sensed lateral movement of the web. The member is located so that lateral movement of the web with the steering roller upon the angular adjustment of the roller is not imparted to the member.
