ABSTRACT:
Resinoid wheels are continuously produced by preparing resinoid abrasive compositions each different in the size of abrasive grains contained therein, placing the abrasive compositions into a die in the form of superposed layers, molding the superposed layers into a block, heating the block by a high frequency heater, passing the heated block through multiple pairs of rolls to roll the block into a sheet, blanking out circular pieces from the rolled sheet and baking the circular pieces.
