ABSTRACT:
In accordance with this invention, there is provided apparatus for removing pin bones from fish fillets, the apparatus having a rotatable bone pulling cylinder and a puller plate defining a pin bone receiving space between the bone pulling cylinder and puller plate. The bone pulling cylinder has a cylindrical surface which is adapted to snag pin bones extending from a fish fillet disposed adjacent to the bone pulling cylinder and puller plate, and the puller plate has a forward portion profiled to have a radius of curvature which is commensurate with the radius of curvature of the cylindrical surface of the bone pulling cylinder. The puller plate is slidably mounted to a body and adapted to be slid toward the bone pulling cylinder to bring the leading edge to mate with the bone pulling cylinder, the relative position of the puller plate to the bone pulling cylinder being maintained by mounting openings provided in the puller plate and the body, and by fasteners received in the mounting openings which couple the puller plate to the body. The fasteners are adapted to apply a minimum predetermined tension to the leading edge of the puller plate over a selected arc length of the bone pulling cylinder so that any pin bones received between the puller plate and the bone pulling cylinder are squeezed, and continued rotation of the bone pulling cylinder withdraws the pin bones from the fish fillet.
