Abstract
The invention provides individually made abrasive discs with the primary abrasive surface around the periphery of the disc where the bulk of the abrading action occurs when the disc is in use. The invention also provides a process by which these discs can be made using a unique grain feeding technique which is capable of depositing abrasive grain on a backing surface accurately and in annular patterns.
