Abstract: An apparatus and procedure for extracting pin bones from fish. The procedure comprises detaching the pin bones from the meat using vibrations, and then, extracting the pin bone using only enough traction force in order to pull out the pin bone, thus preserving its integrity, without damaging the interior and exterior of the meat. The apparatus comprises a vibrations generator, a pin boning device, and a device for transmitting vibrations from the generator to the pin boning device. In a preferred embodiment, the apparatus further comprises a torque generator including a maximum output torque controlling device.
