Abstract
A method for producing endless abrasive articles (100) comprises: —providing a mandrel coil (200), which comprises a first complete turn (BOA) formed of an endless mandrel belt (BO), —feeding the endless mandrel belt (BO) to an input end (INO) of the mandrel coil (200) and unwinding the mandrel belt (B0) from an output end (OUT0) of the mandrel coil (200) so as to move the surface of the first complete turn (BOA) of the mandrel coil (200), —forming a laminated sleeve (SLEEVE1) by feeding a first strip (S1) on the moving surface of the first complete turn (BOA) of the mandrel coil (200), and—forming an endless abrasive article (100) by cutting the laminated sleeve (SLEEVE1).
