ABSTRACT:
An apparatus and method for removing pin bones from a fillet of fish. The apparatus of the present invention uses a plurality of spring-tempered sheet metal disks that each has a periphery that can be either non-linear or linear. The disks are assembled to form a stack of the disks aligned so that the peripheries form at least one "pinch-point," in which the periphery of two disks contact each other, to grip a pin bone. The stack of the disks is rotated and moved over the fillet. The pill bone is disposed between two adjacent rotating disks. As the gap between the disks closes to the pinch-point, the pin bone becomes wedged and is plucked out of the fillet as the wedged pin bone is pulled by the rotating disks.
