ABSTRACT:
A rotating sleeve coaxially mounted upon an inner nonrotating pivoting sleeve by at least two rotary bearings on either side of a center mounted pivoting bearing assembly within the nonrotating pivoting sleeve supported by a stationary shaft. The nonrotating pivoting sleeve is balance-mounted in the center of the axis shaft with the pivoting bearing assembly. The pivoting bearing assembly permits a selected degree of lateral rotation in a range of from about 1 degree to about 10 degrees. As a web runs over the rotating sleeve any imbalance of lateral tension will cause the nonrotating pivoting sleeve to pivot at it's center with respect to the longitudinal axis of the shaft permitting the nonrotating pivoting sleeve and coaxial rotating sleeve to pivot upward on the side of least tension until the web tension is equalized across the coaxial rotating sleeve.
