lying directly on the carcass and the outer breast fillet covering the inner breast fillet lie in their
natural position, and the poultry bodies are transported, the shoulder joints forward, in transport direction T along a transport
route defining the transport plane E, in which the downwardly directed
breast bone oriented in the longitudinal direction of the transport direction T and parallel to it, comprising a pair of for separating the sinews and / or sinew portions from the inner breast fillet, wherein the two separators are located on opposite sides of the transport
route of poultry bodies to be processed, characterized in that the separators are formed as sticking knives wherein each sticking knife is designed and configured to perform at least two
cutting movements in different directions of movement and the two
cutting movements are superimposable is provided. Furthermore, the invention concerns a
processing apparatus having such a sinew separating apparatus and as corresponding method.
