Abstract

Poultry carcasses are conveyed on saddles with their breastbone plate facing downwards to a scraping device having left and right scraping elements arranged adjacent to each other to simulate the contour of the approaching poultry carcass. The scraping elements are spaced apart by a signal from the control unit in relation to the individual width of the poultry carcass. Each scraping element has a sinew restraint that finds and restrains the tender sinew located in the region of the body joint, so that the scraping element can pass unhindered into the region between bone and meat and so obtain an optimum yield. A second scraping device, arranged essentially symmetrically to the direction of conveying, has left and right discs that are slidable by pivot levers to move on the corresponding part of the symmetrical wishbone in order to detach the meat connected to the wishbone.
