Abstract:
A method for preparing abrasive discs from a 8 inch by 50 yard roll of abrasive material comprising the steps of;(a) providing a table support assembly, consisting of;a metal spool support that supports a 8 inch by 50 yard roll of abrasive material,a pair of stationary pinch rollers,a steel rule die punch assembly consisting of a punch actuator,an upper plate consisting of a circular steel rule die embedded on end into a 8 inch by 8 inch wood, metal, or plastic block with rubber (for ejection purposes) mounted inside and outside the blade diameter,a lower plate consisting of a cutting plate consisting of wood, metal, or plastic material to cut against,a disc exit chute consisting of a cut out in the table support assembly,a material removal actuator,a brake and slider assembly that consists of pneumatic actuators,a pneumatic reservoir tank having connecting means for operating various actuators,an electronic pneumatic control board for automating the above apparatus functions,(b) feeding the 8 inch wide abrasive material through the stationary pinch rollers, between the upper and lower plates of the steel rule punch die assembly, between the disc exit chute and the material removal actuator, through the brake and slider assembly, actuating the steel rule die assembly, wherein the punch actuator will press the upper plate against the lower plate thus cutting a disc out of the abrasive material, then the brake and slider assembly will pull the cut disc and surrounding abrasive material between the material removal actuator and the disc exit chute with the said actuator pushing the cut disc down through the disc exit chute to be collected as the steel rule die assembly will again perform the above said function.
