Apparatus for positioning an advancing web

An apparatus for controlling cross-directional movement of a web advancing in a machine direction, wherein the web defines a machine direction centerline, the apparatus comprising:

• a frame having a first end portion and a second end portion separated by a central portion, wherein the frame is rotatable about a first axis of rotation;
• a first rotation member movably connected with the frame, wherein the first rotation member is configured to rotate the frame by a first angle of rotation about the first axis of rotation, and wherein the first rotation member is configured to align a machine direction centerline of an advancing web with a target cross-directional position;
• and
• a second rotation member movably connected with the frame, wherein the second rotation member is configured to rotate the frame about a second axis of rotation by a second angle of rotation, wherein the second angle of rotation is greater than the first angle of rotation, and wherein the second rotation member is configured to adjust the target cross-directional position from a first target cross-directional position to a second target cross-directional position that is different from the first target cross-directional position.

• and
• a first web spacing device and a second web spacing device, wherein each web spacing device comprises the frame, wherein the first web spacing device is configured to shift a first advancing web in a first cross direction and the second web spacing device is configured to shift a second advancing web in a second cross direction, wherein the first cross direction is opposite the second cross direction.
