Abstract

The endless grinding band (1) has abrasive material (4) on at least one side, and a straight transverse butt joint (2) with a connecting strip (3) covering, on the pressurised side. The zones either side of the joint are free of abrasive, or have the adhesive coating thickness reduced over a length of at least 2 mm. This length pref. equals one quarter to one third of that of the connecting strip.
