Claims
- 1. A method of treating a coreless roll of absorbent paper product wound throughout the entire diameter of the roll so as to make it easier for a user to center a winding axis of the coreless roll with respect to a dispenser, comprising steps of:
- (a) positioning a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" adjacent to at least one side of the coreless roll so that the substantially cylindrical tool is substantially centered with respect to the winding axis of the roll; and
- (b) pressing the substantially cylindrical tool into the side of the roll to form a visible depression in the side of the roll that is centered with respect to the winding axis of the roll; whereby persons loading the treated roll onto a dispenser will find it easier to center the roll with respect to a dispenser.
- 2. A method according to claim 1, wherein step (b) is performed by rotating the substantially cylindrical tool about an axis of the tool as the substantially cylindrical tool is pressed into the side of the roll.
- 3. A method according to claim 1, wherein the cylindrical portion of the tool has a diameter that is approximately 5/32".
- 4. A method according to claim 1, wherein step (b) is performed so that the substantially cylindrical tool penetrates into the coreless roll a distance within the range of substantially 1/32" to 1/2".
- 5. A method according to claim 4, wherein step (b) is performed so that the substantially cylindrical tool penetrates into the coreless roll a distance of approximately 3/16".
- 6. A coreless roll of absorbent paper product that is manufactured according to the method set forth in claim 1.
- 7. A method of mounting a coreless roll of absorbent paper product into a dispenser, comprising steps of:
- (a) locating at least one depression that is formed by a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" in at least one side surface of the coreless roll;
- (b) aligning the coreless roll with respect to the dispenser with the aid of the depression; and
- (c) securing the coreless roll onto the dispenser in the aligned position.
- 8. A method according to claim 7, wherein step (a) is performed by locating a pair of depressions in the coreless roll, a first of the depressions being formed by a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" on one side of the roll and substantially centered with respect to a 30 winding axis of the roll, the second depression being formed by a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" on a second, opposite side of the roll and also being substantially centered with respect to the winding axis of the roll.
- 9. A coreless roll of absorbent paper product wound throughout the entire diameter of the roll that is configured to be easier to mount to a rotary dispenser than conventional coreless rolls wound throughout the entire diameter of the roll, comprising:
- a rolled web of absorbent paper product that is rolled about a winding axis into a cylinder having first and second flat ends; and
- a pair of depressions defined in the coreless roll, a first of the depressions being formed by a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" on one side of the roll and substantially centered with respect to a winding axis of the roll, the second depression being formed by a substantially cylindrical tool having a diameter that is within the range of substantially 1/32" to 1/2" on a second opposite side of the roll and also being substantially centered with respect to the winding axis of the roll, the depressions being adapted for guiding a user to center said rolled web with respect to a dispenser, whereby the coreless roll can be conveniently and accurately mounted into the dispenser.
- 10. A coreless roll according to claim 9, wherein said web is not cut to form said depression.
- 11. A coreless roll according to claim 9, wherein said depression formed by pressing the substantially cylindrical tool into said end while a portion of the rolled web that the tool penetrates is damp.
