  • Patent number: 6736717
    Abstract: Method for obtaining an inner fillet and device for mechanically detaching the undesired tendon part from an inner fillet. The poultry carcass is mounted on a fixing member and positioned so that the tendons are exposed. A processing device, comprising rotating cutters, either partially or completely detaches the tendon from the inner fillets. The cutters make a uniform incision at the moment when the inner fillet and the associated tendon are still essentially in their natural position. The fillets may then be removed manually or mechanically from the carcass.
