2. The dispenser according to claim 1 , wherein the housing comprises a front cover.
3. The dispenser according to claim 1 , wherein the first wall comprises a substantially curved portion sized to accommodate the roll.
4. The dispenser according to claim 3 , wherein the first wall comprises a substantially straight portion adjacent to the substantially curved portion and wherein the fixed contact area is positioned about the substantially curved portion and the substantially straight portion.
5. The dispenser according to claim 1 , wherein the discharge chute comprises a chute curved portion about the fixed contact area.
6. The dispenser according to claim 1 , wherein the discharge chute comprises a discharge slot at an end thereof.
7. The dispenser according to claim 1 , wherein the discharge chute comprises one or more protrusions therein.
8. The dispenser according to claim 1 , wherein the discharge chute comprises a restricted width therein.
9. The dispenser according to claim 8 , wherein the restricted width comprises a slot width that is less than a roll width.
10. The dispenser according to claim 1 , wherein the discharge chute comprises one or more apertures therein.
11. The dispenser according to claim 10 , wherein the one or more apertures comprise an upper aperture and wherein the upper aperture extends into the first wall.
12. The dispenser according to claim 1 , wherein the roll support mechanism comprises at least one biasing member to bias the roll against the fixed contact area.
13. The dispenser according to claim 1 , wherein the roll support mechanism comprises a pair of arms for supporting the roll therebetween.
14. The dispenser according to claim 13 , wherein each of the pair of arms comprises a plug cup thereon sized to accommodate a plug of the roll.
15. The dispenser according to claim 13 , wherein the roll support mechanism comprises a pair of rails for the pair of arms to maneuver thereon.
16. The dispenser according to claim 13 , wherein the roll support mechanism comprises one or more springs in communication with the pair of arms.
17. The dispenser according to claim 1 , wherein the first wall comprises a front cover.
18. The dispenser according to claim 1 , wherein the first wall comprises a top cover.
19. The dispenser according to claim 1 , wherein the first wall comprises a front wall.
20. A method of dispensing sheet product from a roll of sheet product in a dispenser, comprising:
positioning the roll within the dispenser in an underfeed orientation;
forcing the roll against a wall of the dispenser;
pulling a first sheet product through a discharge chute with a restricted width; and
separating a number of perforations between the first sheet product and a second sheet product as the number of perforations pass in or about the restricted width.
21. A dispenser for a roll of sheet product, comprising:
a housing;
the housing comprising a first wall;
the first wall comprising a discharge chute;
the discharge chute comprising a restricted width; and
a roll support mechanism positioned within the housing;
the roll support mechanism forcing the roll against the first wall.
22. The dispenser according to claim 21 , wherein the first wall comprises a front cover.
23. The dispenser according to claim 21 , wherein the discharge chute comprises a discharge slot at an end thereof.
24. The dispenser according to claim 23 , wherein the restricted width is positioned about the discharge slot.
25. The dispenser according to claim 23 , wherein the discharge slot comprises one or more protrusions therein.
26. The dispenser according to claim 21 , wherein the restricted width comprises a slot width that is less than a roll width.
27. The dispenser according to claim 21 wherein the discharge chute comprises one or more apertures therein.
28. The dispenser according to claim 27 , wherein the one or more apertures comprise an upper aperture and wherein the upper aperture extends into the first wall.
29. A method of dispensing sheet product with perforations from a roll of sheet product in a dispenser, comprising:
positioning the roll within the dispenser;
pulling a first sheet product in a tangential direction away from the roll;
passing the first sheet product through a discharge chute with a restricted width;
forcing the roll against a wall of the dispenser; and
separating a number of perforations between the first sheet product and a second sheet product as the number of perforations pass in or about the restricted width.
30. A method of loading a roll of sheet product into a dispenser, comprising:
placing the roll in a curved cover of the dispenser;
biasing a roll support mechanism towards the roll in the curved cover of the dispenser;
rolling the roll into the roll support mechanism; and
closing the curved cover.
