Abstract
An improved machine and method for lifting, loading, and maintaining a web roll on a cantelevered spindle so that the web roll may rotate about the longitudinal axis of the spindle thereby permitting the web to be unwound from the web roll. The cantelevered spindle of this machine may be moved, vertically and horizontally, from its normal, unwind position so as to be insertable into the central core opening of the web roll while the web roll is positioned on the floor adjacent to the machine. Thereafter the spindle, and the web roll mounted on the spindle, are moved vertically and horizontally and are returned to the spindle's normal web unwind position. The means utilized to move the spindle horizontally during web roll lifting and loading is also used, in part, to adjust the position of the web roll, during the web unwinding operation, in response to signals from a side-lay sensing device employed to sense the position of the side edge of the web being unwound.
