Web media moving method

Abstract

A method of moving a continuous web of print media includes providing a roller having an axis of rotation. The roller includes a pattern of recesses and ridges positioned along the axis of rotation of the roller. A second section of the roller is located between a first section of the roller and a third section of the roller as viewed along the axis of rotation. The roller includes a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller. A web of print media is caused to contact and wrap around a portion of the roller as the web of print media moves past the roller.

1 . A method of moving a continuous web of print media comprising:
 providing a roller having an axis of rotation, the roller including a pattern of recesses and ridges positioned along the axis of rotation of the roller, the roller including a first section, a second section, and a third section, the second section being located between the first section and the third section as viewed along the axis of rotation, the roller including a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller; and   causing the web of print media to contact and wrap around a portion of the roller as the web of print media moves past the roller.   
     
     
         2 . The method of  claim 1 , wherein causing the web of print media to contact and wrap around a portion of the roller as the web of print media moves past the roller further comprises:
 providing a first nip roller positioned to engage a first ridge of the ridges of the roller and a second nip roller positioned to engage a second ridge of the ridges of the roller;   causing the web of print media to pass between the first nip roller and the first ridge and to pass between the second nip roller and the second ridge; and   driving the roller.   
     
     
         3 . The method of  claim 1 , wherein causing the web of print media to contact and wrap around a portion of the roller as the web of print media moves past the roller further comprises:
 providing the roller that freely rotates about its axis of rotation; and   moving the web of print media past the roller using a print media driving mechanism.
