Method for transporting print media

Abstract

A turnbar for use in a turnover module in a printing system includes one or more air-cushioned sections and one or more friction sections. Each air-cushioned section includes holes formed in a portion of a perimeter of the turnbar. Each friction section includes a friction-inducing material disposed over or affixed to another portion of the perimeter of the turnbar. Pressurized air or gas is output through the holes to produce a cushion of air or gas between a print media and the air-cushioned section. The turnbar can include one or more pistons within the turnbar, or one or more sleeves within or around the turnbar, or a combination of pistons and sleeves, to adjust airflow through the air-cushioned section.

1 . A method for transporting a print media over a turnbar in a turnover module in a printing system, the method comprising:
 outputting air through an air-cushioned section in the turnbar, where the air cushioned section includes a plurality of holes in a portion of a perimeter of the turnbar; and   adjusting airflow through the air-cushioned section.   
     
     
         2 . The method as in  claim 1 , wherein adjusting airflow through the air-cushioned section comprises adjusting airflow through the air-cushioned section based on one or more properties of the print media. 
     
     
         3 . The method as in  claim 2 , wherein the one or more properties of the print media include a width of the print media. 
     
     
         4 . The method as in  claim 2 , wherein the one or more properties of the print media include a thickness of the print media.
