ABSTRACT:
A bidirectional pivot frame of a paper web changing device is supported for pivotal motion about a selected one of two pivot axes. The support for the pivot frame is accomplished by slidable locking supports that positively lock one set of pivot pins in place in guide slots in the side frames of the paper web changing device, while releasing a second set of guide pins. The slidable locking supports are shiftable to selectively positively lock the desired set of guide pins in place.
