The coefficient of friction of printing and writing paper is an indicator of the ease with which the top or bottom sheets of a stack of paper will slide across the succeeding sheet, such as a occurs on the infeed of a printing press or the sheet transport into a copier machine.

Suitable for testing as per following Standard

• TAPPI T549

Applications:

• The machine helps us to calculate the coefficents of static and kinetic friction of uncoated writing and printing paper laminates, composites etc. by horizontal plane method.
• The finding of this test help in preventing double feeding in printing press and copier machine.
