Abstract:
1. Process for introduction of at least one groove ( 92 , 93 , 94 , 95 , 96 , 97 , 98 ) into a friction layer ( 91 ) of a friction disk ( 90 ) for a force transmission aggregate, comprising a rolling device ( 1 , 11 , 21 , 31 ) forming at least one groove ( 92 , 93 , 94 , 95 , 96 , 97 , 98 ), the rolling device ( 1 , 11 , 21 , 31 ) having at least one roller flange ( 7 , 17 , 27 a . . . 27 f , 37 a . . . 37 c ) for roller forming the at least one groove ( 92 , 93 , 94 , 95 , 96 , 97 , 98 ), wherein the rolling device ( 1 , 11 , 21 ) includes a drive shaft ( 4 ) rotatable (ω) about a rotation axis (R), upon which at least one template disk ( 2 , 12 , 22 a . . . 22 f ) is provided co-axially, the at least one template disk having an outer circumference ( 8 , 18 , 28 ) which forms the at least one roller flange ( 7 , 17 , 27 a . . . 27 f ; the at least one groove ( 92 , 93 , 94 , 95 , 96 , 97 , 98 ) is roller formed immediately after a step of gluing the friction layer ( 91 ) to a carrier material.
