ABSTRACT:
A printing press idle roller braking system is provided with a friction member mounted to the printing press frame for making frictional circumferential contact with an outer circumferential periphery of a cylindrical idle roller to reduce and control the speed of rotation of the cylindrical idle roller to prevent accumulation of ink and lint on the outer circumferential periphery and create tension in the web sheet.
