Abstract

A method for obtaining leg meat from poultry drumsticks and an apparatus for performing the method are described. Deriving from an apparatus by which, following the performance of an encircling cut in the region of the distal condyle (41) and the consequent severing of the tendons, skins and ligaments of the drumstick bone (44) under retention of the leg meat is pulled by means of a strip-off diaphraghm, an apparatus is described by which a pair of gripping elements (17 and 18) are provided, which can be brought into a position for gripping around the drumstick bone (44) and each of which is respectively provided with a recess (20) in this embracing region, which can be aligned laterally displaced with regard to the position of the drumstick bone (44), and by which apparatus a severing device (16) is integrated with the gripping elements (17 and 18), the cutting mechanism of which is effective immediately next to the recess (20). The object is to guide a severing cut which leaves the tendons (47) constituting the continuation of the splint bone toward the distal end uncut/intact with the effect that the splint bone is also pulled along with the drumstick bone (44).
