A pin bone removing apparatus for removing pin bones from fish fillets includes a drive train and a rotatable cylinder head coupled to the drive train. The apparatus includes a torque limiter, which for a preset torque value will uncouple the rotatable cylinder head from the drive train. A method is also provided for removing pin bones from fish fillets, by pinching the pin bone in question between a rotating cylinder with recesses and a resilient tongue in contact with the cylinder. During the pinching, the pulling force is applied to the fish pin bone until the force reaches a preset level, at which the pulling is interrupted for a short period of time, unless the pin bone immediately comes loose, and if it does not come loose the pulling force is applied again until it reaches the preset level, and this process is repeated until the bone comes loose. |
