Pin bone remover

A cylinder head for a pin bone removing apparatus, comprising means for coupling the cylinder head to a drive axis, the cylinder head comprising a torque limiter provided inside the cylinder head wherein the torque limiter is arranged to transfer rotational motion from the drive axis to the cylinder head, and to uncouple the drive axis when a preset torque is reached.

A method of removing pin bones from fish fillets, comprising pinching the pin bone between a rotating cylinder with recesses and a resilient tongue in contact with the cylinder, whereby when the pinching is performed a pulling force is applied to the fish bone;

• wherein during the pinching, the pulling force is applied to the fish pin bone until the force reaches a preset level, at which point the pulling is interrupted for a short period of time, unless the pin bone immediately comes loose, and
• if said pin bone does not come loose the pulling force is applied again until it reaches the preset level, this process being repeated until the bone comes loose.
