Abstract

A support spindle assembly for rotatably supporting a coreless paper roll for dispensing, the support spindle assembly including a spindle base, a spindle element having a central longitudinal axis (X) and having first and second ends, the spindle element being attached to the spindle base at the first end and rotationally fixed in relation to the spindle base and a rotatable sleeve rotatably disposed about the spindle element, and rotatable in relation to the spindle base and to the spindle element. The support spindle assembly includes a resilient member disposed about the first end of the spindle element, which resilient member is arranged to cooperate with the spindle base and with the rotatable sleeve in order to provide the rotatable sleeve with a rotational resistance.

First claim

What is claimed is:

1. A support spindle assembly for rotatably supporting a coreless paper roll for dispensing, the support spindle assembly, comprising:
a spindle base;
a spindle element extending along a central longitudinal axis and having a first end and a second end, said spindle element being attached to said spindle base at said first end and rotationally fixed in relation to said spindle base;
a first rotatable sleeve rotatably disposed about said spindle element, and rotatable in relation to said spindle base and to said spindle element; and
a resilient member disposed about said first end of said spindle element and configured to cooperate with said spindle base and with said first rotatable sleeve to exert an axial force directly or indirectly on the rotatable sleeve in order to provide said rotatable sleeve with rotational resistance caused by friction during unwinding.

2. The support spindle assembly according to claim 1 , wherein said first rotatable sleeve includes a body that is axially elongated in the direction of the central longitudinal axis (X) of said spindle element, said first rotatable sleeve including a first end and a second end, wherein said first end of said first rotatable sleeve has an enlarged part having a radius larger than a radius of the body of said first rotatable sleeve, and wherein said resilient member is configured to cooperate directly or indirectly with said enlarged part.

3. The support spindle assembly according to claim 2 , wherein said enlarged part extends over said resilient member such that said resilient member cooperates with an interior surface of said enlarged part.

4. The support spindle assembly according to claim 2 , wherein said enlarged part is an integral part of said first rotatable sleeve.

5. The support spindle assembly according to claim 1 , wherein said first rotatable sleeve is removably mounted about said spindle element, and said resilient member is compressed when said first rotatable sleeve is mounted about said spindle element.

6. The support spindle assembly according to claim 1 , wherein said resilient member includes a first end, said first end of said resilient member abutting said spindle base.

7. The support spindle assembly according to claim 1 , wherein said resilient member includes a first end, said first end of said resilient member being attached to said spindle base.

8. The support spindle assembly according to claim 1 , further comprising a bushing positioned between said resilient means and said first rotatable sleeve, said resilient means including a second end abutting said bushing and said bushing being in contact with said rotatable sleeve in the axial direction and being configured to press against said first rotatable sleeve in the direction of the central longitudinal axis.

9. The support spindle assembly according to claim 8 , wherein said enlarged part of said first rotatable sleeve includes a friction surface on an interior surface thereof, said friction surface facing said bushing, said bushing being in abutting engagement with said friction surface.

10. The support spindle assembly according to claim 9 , wherein said friction surface is an annular friction rib.

11. The support spindle assembly according to claim 8 wherein said bushing engages said spindle base or said spindle element in the radial direction, so that said bushing is locked against rotation relative to said spindle base and said spindle element.

12. The support spindle assembly according to claim 1 , wherein said resilient member is a compression spring, said compression spring being configured to be compressed and to exert a force on said first rotatable sleeve.

13. The support spindle assembly according to claim 1 , wherein said second end of said support spindle is configured to engage a locking element.

14. The support spindle assembly according to claim 1 , further comprising at least two spindle elements and a second rotatable sleeve, each of said first and second rotatable sleeves being rotatably disposed about a respective one of said at least two spindle elements.

15. The support spindle assembly according to claim 14 , wherein said at least two spindle elements are respectively attached to the spindle base at their respective first ends and rotationally fixed in relation to said spindle base.
