Abstract

A towel roll brake is not needed in this "grab and pull" dispenser to prevent the overspun towel from the roll from entering the nip region. An extra idler roll rests on the pinch roll and is counterrotated thereby, and any overspun web resting on the idler roll is kicked to the back of the dispenser. Fingers formed on the inside surface of the dispenser cover are positioned to derfine with the idler roll a gap which is only one-ply wide and through which the toweling must pass to reach the nip region, thereby preventing the overspun web from folding over onto itself. Without the brake tearing or "tabbing" of the soft towel in the user'"'"'s (wet) hands as he pulls down on it is prevented.

Claims

1. A flexible sheet material dispenser, comprising:

a dispenser cabinet;

holding means for holding a roll of flexible sheet material in said cabinet such that the roll can rotate within said cabinet and overspin as a user hand pulls a free end of the sheet of material therefrom;

a roller positioned in said cabinet;

gap means for defining with said roller and therebetween as essentially one-ply wide sheet material gap through which sheet material from the held roll passes;

cutting means for cutting a length of sheet material hand pulled off of the held roll and passing through the gap; and

counterrotating means for counterrotating said roller such that at least some of the time when an overspun web of sheet material, before passing through the gap, rests on said roller the resting web is kicked generally away from the gap.

2. The dispenser of claim 1 wherein said cabinet defines therewithin a dickback area into which said roller kicks the resting web.

3. The dispenser of claim 2 wherein said kickback area is generally below the held roll.

4. The dispenser of claim 2 wherein said kickback area is generally to one side of the held roll.

5. The dispenser of claim 4 wherein said kickback area is also generally below the held roll.

6. The dispenser of claim 1 wherein said cabinet includes an elongated opening downstream of the gap and out through which the free end of the sheet material off of the held roll passes, accessible for user hand pull.

8. The dispenser of claim 1 wherein said counterrotating means rotates said roller in a counterclockwise direction.

9. The dispenser of claim 1 further comprising nip means for defining at least in part a nip area through which the one-ply wide sheet material passes after passing through the gap and before being cut by said cutting means.

10. The dispenser of claim 9 wherein said counterrotating means kicks the resting web away from the nip area.

11. The dispenser of claim 1 wherein said counterrotating means kicks the resting web to the back of said cabinet.

12. The dispenser of claim 1 wherein said cabinet includes a cover, and said gap means is mounted on said cover.

13. The dispenser of claim 12 wherein said cover is pivotably positionable between a normal closed position and an open position wherein the held roll is accessible, and said gap means is movable therewith.

14. The dispenser of claim 12 wherein said gap means comprises a plurality of spaced finger members secured to an inside surface of said cover.

15. The dispenser of claim 14 wherein said finger members comprise first and second horizontally spaced finger members.

16. The dispenser of claim 12 wherein said gap means is molded to said cover.

17. The dispenser of claim 1 wherein said roller is rotatable by said counterrotating emans about a horizontal axis.

18. The dispenser of claim 1 wherein said gap means is positioned in the same horizontal plane as that of said roller.

19. The dispenser of claim 1 further comprising a mechanism housing disposed in said cabinet and defining a pair of spaced slots in which axle ends of said roller rotate.

20. The dispenser of claim 1 wherein said counterrotating means includes a drive roll which when rotated drives said roller.

21. The dispenser of claim 20 wherein said drive roll frictionally drives said roller along generally the length thereof.

22. The dispenser of claim 20 wherein said roller rests with its weight on said drive roll.

23. The dispenser of claim 20 wherein said drive roll comprises a spring-loaded roller.

24. The dispenser of claim 20 wherein said cutting means comprises a knife roll, and said knife roll and said drive roll define a toweling nip region therebetween.

25. The dispenser of claim 24 wherein said drive roll is spring-loaded against said knife roll.

26. The dispenser of claim 1 wherein said cutting means includes a cutting mechanism and a nip region immediately upstream of said cutting mechanism, and said counterrotating means prevents overspun web from the held roll from entering said nip region.

27. The dispenser of claim 1 wherein said counterrotating means includes a spring-loaded sheet material pinch roller.

28. The dispenser of claim 1 wherein said counterrotating means rotates said roller when and only when a user is pulling on the free end of the sheet material.

29. The dispenser of claim 27 wherein said cutting means comprises a knife roll rotatably disposed in said cabinet.

30. The dispenser of claim 1 wherein said roller comprises an idler pinch roller, and said counterrotating means rotates said idler pinch roller in the direction opposite to a feed direction of the sheet material from the held roll.

31. The dispenser of claim 1 further comprising feedout means for feeding, a short time after a length of sheet material has been cut by said cutting means, a lead length of the sheet material from said dispenser so as to be accessible to the next user.

7. The dispenser of claim 7 wherein said elongated opening is downstream of said cutting means.
