Abstract
A method of producing finishing chips comprising the steps of providing a castable mixture of particulate abrasive grains and a solidifiable matrix, depositing the mixture into cavities of a generally-cylindrical, flexible mold having a plurality of cavities in the interior surface thereof conforming to the desired configuration of finishing chips to be produced, rotating said cylindrical mold during solidification of said mixture and the production of solid finishing chips within said cavities, and ejecting said solidified finishing chips from said mold by bringing said mold to an inside-out position, whereby said solidified finishing chips are ejected from said cavities, is disclosed. Apparatus which may be employed in carrying out the method, representatively comprising a generally-cylindrical chamber supported on a hollow shaft which is mounted for rotation, a flexible mold disposed within said chamber, and means associated with the bottom of said mold and operative through and within said hollow shaft for positioning said mold in chip-molding location within said chamber or in inside-out chip-ejecting location outside of said chamber, is also disclosed.
