Coated abrasive belt

A coated abrasive belt comprising a flexible substrate and an abrasive grain layer on one side thereof, said abrasive belt having a belt running direction, said substrate comprising a longitudinal strength layer (4,5), designed for absorbing the largest part of the forces appearing in the belt running direction, and a transverse strength layer (6, 7), designed for absorbing the larger part of the forces extending transversely relative to the belt running direction;

• said belt having at least two end portions (2,3) connected to one another by means of at least one adhesive seam (1) extending transversely relative to the belt running direction;
• each of said end portions having a recess on the side of the transverse strength layer (6, 7), said recess (8) forming a connecting seam face (10) which extends approximately in said belt running direction and reaches at least near to the longitudinal strength layer (4, 5) to define a seam strip of the longitudinal strength layer (4, 5), each of said seam strips being complementary to and projecting into the recess (8) of the other end portion, the connecting faces (10) of the two recesses being adhesively bonded directly to one another, one of said two portions (2) carrying said grain layer (14) on its longitudinal strength layer (4) and the other portion (3) carrying it on its transverse strength layer (7).
