Abstract

By complete removal of the friction lining material, grooves or slots are formed in a friction lining made of organic material, the grooves being openings or gaps that are initially closed at the ends. The friction lining is applied as a continuous member onto a support and the ends of the grooves are opened by removal of the friction lining material closing them.
