<p>TITLE: SHEET LIFTER FOR LOOSE LEAF RING BINDERS AND METHOD OF INSTALLING SHEET LIFTERS IN LOOSE LEAF RING BINDERS. A sheet lifter for a ring binder has slits connecting the edge of the sheet lifter to the holes for the rings. The slits are preferably tangential to the sides of the holes, and one slit is preferably offset toward the opposite side of the lifter from the other slit or slits. The lifter is made of resilient yielding material so that it may be simply pressed onto the rings without opening the rings but cannot easily be removed without opening the rings. A method is also described for installing the sheet lifter in similar manner.</p> |
