ATTORNEYS END CORE FOR ROLLS OFlPAPER The present invention relates toend cores for rolls of paper and more particularly to an end core adapted to maintain inner layers of the roll of paper in tension and rotatably support same.
The principal objects of the present invention are: to provide an end core for mounting in opposite ends of a roll of paper and resiliently engaging same for rotatably supporting same; to provide such an end core adapted to maintain inner layers of the roll of paper in tension; to provide such an end core adapted to be maintained in compression when installed in one end of the roll of paper; to provide such an end core having an end wall adapted to engage one end of the roll of paper and an outer core wall adapted to maintain positive engagement with the inner layer of the roll of paper; to provide such an end core having a crowned end wall adapted to serve as a bearing for rotatably supporting a vertical roll of paper for dispensing therefrom; and to provide such an end core which is economical to manufacture, easily installed in rolls of paper, and particularly well suited for the proposed use. Other objects and advantages of this invention will become apparent from the following description taken inconnection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this inven tion.
FIG l is an elevational view of a vertical roll of paper having end cores therein which embody features of the present invention.
FIG 2 is an enlarged side elevational view of one of the end cores.
FIG 3 is an enlarged end elevational view of the end core.
FIG 4 is a longitudinal sectional view taken on line 4-4, FIG 3.
FIG is an elevational view of a vertical roll of paper having a modified end core in'each end thereof.
FIG 6 is an enlarged side elevational view of the modified end core. x
Referring more in detail to the drawings:
The reference numeral 1 generally designates a hollow roll of paper having an end core 2 placed in opposite ends thereof for rotatably supporting the roll of paper 1.
The end core 2 has a generally annular end wall 3 having an inner peripheral edge 4 forming a centrally positioned circular aperture therein. An elongated slot 5 extends radially between the inner peripheral edge 4 and an outer peripheral edge 6 of the end wall 3, thereby defining opposite ends of the end wall 3.
Concentric inner and outer core walls 7 and 8, respectively, are connected to and extend from the end wall 3. The outer core wall 8 is normally of a size slightly larger than the interior size of the hollow roll of paper l which is adapted to receive the end core 2 therein. An inner periphery or inner surface 9 of the inner core wall 7 registers with the inner peripheral edge 4 of the end wall 3 and the outer core wall 8 is positioned adjacent the outer peripheral edge 6 of the end wall 3 defining a lip or annular flange 10 extending substantially radially outwardly from the outer core wall 8 for engaging an end of the roll of paper 1. The inner and outer core walls 7 and 8 each have fixed ends 11 and 12, respectively, connected to the end wall 3 and free ends 13 and 14, respectively. End edges of the inner and outer core walls 7 and 8 terminate at the slot 5 in the end wall 3 thereby defining longitudinal slots through the core walls which extend longitudinally for the length thereof.
Reinforcement members 15 are circumferentially spaced and extend radially between the inner and outer core walls 7 and 8, with a pair of the reinforcing members 15 being in facing relation with facing surfaces aligned with the slot 5 thereby defining an elongated radial slot through the end core 2. The radial slot extends longitudinally for the length of the inner and outer core walls 7 and 8 thereby permitting the facing reinforcing members 15 to move toward and away from each other to vary the exterior diameter of the end core 2.
The end wall 3 forms an acute angle with the longitudinal axis of the end core 2 whereby the inner peripheral edge 4 of the end wall 3 is outwardly of a plane extending through the outer peripheral edge 6 and normal to the inner and outer core walls 7 and 8.
When the roll of paper I is placed in a vertically standing I osition, the end core 2 will support the weight of the roll of paper 1 on the end wall 3 and the inner core wall 7. Paper may be dispensed from the roll of paper 1 with the end core 2 func tioning as a bearing member for rotatably supporting the roll of paper 1.
The inner peripheral surface of the outer core wall 8 is spaced at a constant radius from the longitudinal axis of the end core 2 and the thickness of the outer core wall 8 gradually reduces from the fixed end 12 to the free end 114 and the outer core wall 8, therefore, has a greater exterior diameter at the fixed end 12 than at the free end 14. Placing the end core 2 in one end of the roll of paper 1 moves the facing reinforcing members 15 toward each other, thereby reducing the transverse dimension of the'slot 5 and the spacing between the facing reinforcing members 15.
The end core 2 is formed of a suitable resilient material, whereby the end core 2 attempts to regain its original shape, thereby placing the inner layer of the roll of paper 1 in tension through frictional engagement between the exterior surface of the outer core wall 8 and the inner layersof paper.
In use, the outer core wall 8 is squeezed thereby reducing the diameter thereof prior to placing the end core 2 in the hollow roll of paper 1. The normal or relaxed exterior diameter of the outer core wall 8 is slightly larger than the interior diameter of the hollow roll of paper I, therefore, when the end core 2 is within the roll of paper 1, the end core 2 will be maintained in compression and the inner layers of paper will be placed in tension. The roll of paper 1 may be rotatably mounted in a horizontal position by extending an elongated shaft or rod (not shown) through the end cores 2 placed therein. When the roll of paper 1 is vertical and supported on the end core 2, the end wall 3 will serve as a bearing for rotating the roll of paper for dispensing paper therefrom.
FIG 6 illustrates a modified end core 16 having a generally planar end wall 17, whereby rolls of paper having the modified end core 16 in opposite ends thereof may be stacked vertically. The modified end core 16 also has an annular flange 18 which extends radially outwardly from an outer core wall 19 for engaging an end of the roll of paper, whereby the end wall 17 is positioned outwardly of the end of the respective roll of paper, thereby permitting the roll of paper 1 to be rotated on the modified end core 16 as a bearing.
