ABSTRACT:
A coated abrasive belt with an abrasive grain layer on one side of a flexible substrate. The substrate comprises a longitudinal strength layer (4, 5) and a transverse strength layer (6, 7). The edges of successive coated abrasive belt portions are adhesively bonded directly to one another by the use of a recess formed at least in the transverse strength layer. Adhesive bonding takes places one a connecting face (10) which runs approximately in the longitudinal direction and which reaches at least near to the longitudinal strength layer (4, 5). One of the two portions (2) carries the grain layer (14) on its longitudinal strength layer (4) and the other carries it on its transverse strength layer (7).
