Electric dispenser for dispensing sheets from a roll of perforated web material
First Claim
1. An electronic dispenser for dispensing measured perforated sheets from a roll of perforated web material, comprising:
- a housing, and a roll carrier disposed in said housing to rotationally support the roll of perforated web material, said housing further comprising a dispensing slot defined therein through which the sheets of the web material are dispensed;
an electrically driven feed mechanism disposed in said housing to dispense the sheets of web material therefrom;
said feed mechanism comprising rollers defining a drafting zone between upstream an downstream nip points having different respective conveying speeds through which the web material is conveyed, the web material being tensioned in said drafting zone to an extent necessary to at least partially separate the web material along a perforation line prior to the perforation line passing through said drafting zone; and
wherein upon activation of said dispenser, a user is presented with a tail a measured sheet of the web material extending from said dispensing slot, the upstream end of the sheet being at least partially separated along the perforation line so that minimal force is exerted by the user to pull the sheet from said dispenser.

Abstract
An electronic dispenser for dispensing measured perforated sheets from a roll of perforated web material includes a housing, and a roll carrier disposed in the housing to rotationally support the roll of perforated web material. An electrically driven feed mechanism is disposed in the housing to dispense the sheets of web material therefrom. The feed mechanism includes rollers defining a drafting zone through which the web material is conveyed. The web material is drawn in the drafting zone to an extent necessary to at least partially separate the web material along a perforation line prior to the perforation line passing through the drafting zone.

12. An automatic electronic dispenser for dispensing measured perforated sheets from a roll of perforated web material, comprising:
-
a housing, and a roll carrier disposed in said housing to rotationally support a roll of perforated web material, said housing further comprising a dispensing slot defined therein through which the sheets of the web material are dispensed; a sensor disposed to detect the presence of a user and to automatically initiate a dispense sequence to dispense a sheet of the web material; an electrically driven teed mechanism disposed in said housing to dispense the sheets of web material therefrom; said feed mechanism comprising rollers defining a drafting zone through which the web material is conveyed, said drafting zone rollers defining an upstream nip point and a downstream nip point, each of said nip points comprising a driven roll and an idler roll, the conveying speed at said downstream nip point being greater than said upstream nip point to define a desired degree of draft within said drafting zone such that the web material is at least partially separated along a perforation line prior to the perforation line passing through said drafting zone; and wherein upon activation of said dispenser, a user is presented with a tail of a measured sheet of the web material extending from said dispensing slot, the upstream end of the sheet being at least partially separated along the perforation line so that minimal force is exerted by the user to pull the sheet from said dispenser. - View Dependent Claims (13, 14, 15, 16)
