<p>There is prpvided a dispenser (10) for rolls of paper(12), including a housing with two spaced-apart sides (16, 16') and a rigid member (18) connecting the spaced-apart sides and one axle (20) extending between the sides, the axle having a plurality of rollers (22, 24) strung therealong and rotatable thereabout and being positioned to engage a curved surface of a roll' of paper placed in the dispenser. A plurality of the rollers is arranged for at least partial non-circular rotation wherein a point on the outer surface of the rollers ascribes an elliptical path while engaging a surface of the roll of paper. The rollers are arranged for elliptical rotation, which will impart to the roll of paper a rocking and wobbling motion, thereby reducing the contact, friction and drag between the surfaces of the roll of paper and the surfaces of the remaining rollers along the axis.</p> |
