Product, Dispenser and Method of Dispensing Product

Abstract

A method for fabricating a roll of sheet product includes forming reference indications on portions of a sheet material, wrapping the sheet material about a spindle to form a core about the spindle, wrapping a sheet product about the core to form a log, removing the spindle from the log, and cutting the log into individual rolls of sheet product, wherein the log is cut proximate to the reference indications such that the reference indications are arranged at a first distal end of each of the individual rolls of sheet product.

What is claimed is: 
     
         1 . A method for fabricating a roll of sheet product, the method comprising:
 forming reference indications on portions of a sheet material;   rotating a spindle to facilitate wrapping of the sheet material about the spindle to form a core about the spindle;   rotating the core to facilitate wrapping of a sheet product about the core to form a log;   separating the spindle with respect to the log; and   cutting the log into individual rolls of sheet product, wherein the log is cut proximate to the reference indications such that the reference indications are arranged at a first distal end of each of the individual rolls of sheet product.   
     
     
         2 . The method of  claim 1 , wherein the forming the reference indications to the portions of the sheet material includes:
 indexing the sheet material to identify regions of the sheet material that correspond to the distal ends of the individual rolls of sheet product; and   applying reference indications in the identified regions of the sheet material.   
     
     
         3 . The method of  claim 1 , wherein the reference indications are arranged on an interior surface of the core. 
     
     
         4 . The method of  claim 1 , wherein the sheet material is wrapped in an overlapping spiral about the spindle. 
     
     
         5 . The method of  claim 1 , wherein the wrapping the sheet material about a spindle to form a core about the spindle includes aligning the reference indications with portions of the spindle corresponding to positions of cutting devices. 
     
     
         6 . The method of  claim 1 , wherein the method further includes cutting the sheet material along a line substantially perpendicular to a rotational axis of the spindle prior to wrapping the portion of sheet material about the spindle. 
     
     
         7 . The method of  claim 1 , wherein the reference indications are formed from a fluid applied to the sheet material. 
     
     
         8 . The method of  claim 1 , wherein the reference indications are formed from an adhesive backed label applied to the sheet material. 
     
     
         9 . The method of  claim 1 , wherein the reference indications are formed at periodic intervals along a longitudinal axis of the sheet material. 
     
     
         10 . The method of  claim 1 , wherein the reference indications are operative to be sensed by a dispenser device. 
     
     
         11 . The method of  claim 1 , wherein the wrapping the sheet material about the spindle includes arranging the sheet material such that the reference indications contact a surface of the spindle. 
     
     
         12 . The method of  claim 1 , wherein the log is cut proximate to the reference indications such that the reference indications are arranged at both the first distal end and an opposing second distal end of each of the individual rolls of sheet product. 
     
     
         13 . The method of  claim 1 , wherein the sheet material includes a strip of material having a first edge and a second edge substantially parallel to the first edge, wherein a length of the material is greater than a perpendicular distance between the first edge and the second edge. 
     
     
         14 . A roll of sheet product comprising:
 a tubular core portion having:
 an inner cavity; 
 an outer surface; 
 first distal end; and 
 a second distal end opposing the first distal end; 
   a sheet product wrapped around the tubular core portion; and   a first reference indication arranged at the first distal end of the tubular core portion.   
     
     
         15 . The roll of sheet product of  claim 14 , wherein the first reference indication is arranged in the inner cavity. 
     
     
         16 . The roll of sheet product of  claim 14 , wherein the roll further comprises a second reference indication arranged in the inner cavity at the second distal end. 
     
     
         17 . The roll of sheet product of  claim 14 , wherein the first reference indication is arranged proximate to only the first distal end. 
     
     
         18 . A system for fabricating a roll of sheet product, the system comprising:
 a controller;   a marking device communicatively connected to the controller, the marking device operative to form a reference indicator on a portion of a sheet material upon receiving a signal from the controller; and   a sensor communicatively connected to the controller, the sensor is operative to determine a position of the portion of sheet material relative to the marking device and send a signal to the controller indicative of the position of the portion of the sheet material.   
     
     
         19 . The system of  claim 18 , wherein the system further includes a sheet product roll fabrication portion operative to receive the sheet material following the formation of the reference indicator and form the sheet material into a core of a roll of sheet product. 
     
     
         20 . The system of  claim 18 , wherein the sensor includes a position sensor.
