  • Patent number: 6997797
    Abstract: A device for processing slaughtered animals or parts thereof, having a first station and a second station, comprises a conveyor which extends between the first station and the second station. The conveyor comprises at least one slot which is designed to carry and support the slaughtered animals, a supply device for supplying the slaughtered animals or parts thereof at the first station on the conveyor, and a discharge device for discharging the slaughtered animals or parts thereof from the conveyor at the second station. The device has at least one driven driving member which spans at least half of the width of the slot, passes through a path which is substantially parallel to the course of the slot and is designed to move the slaughtered animals or parts thereof which are in the slot along the slot.

  • Patent number: 5248277
    Abstract: Method and device for processing the skin of a leg of a slaughtered bird. The bird or leg is moved along in a conveyor. The skin of the leg is cut through completely or almost completely in the vicinity of the knee joint between the region of the kneecap and the region of the back of the knee, the tissue lying under the skin remaining essentially intact, by conveying the leg past a cutting device and putting it in contact therewith. The leg is supported by leg positioning elements while it is passing the cutting device. The cutting depth of the cutting means is limited by a stop which is connected to the cutting means. Provision is made for a stripping device for stripping the severed thigh skin away from the suspended leg downwards. Provision is also made for a roll-up device for rolling up the drumstick skin prior to separating the leg into a thigh portion and a drumstick.

  • Patent number: 5173077
    Abstract: A method and device for performing an accurate cutting operation near the knee joint of a leg of a slaughtered animal, in particular a bird, the device comprising mechanical means, such as conveying elements and guides, for handling the leg, and cutting means, such as rotary or stationary knives for performing the cutting operation, e.g. for making an incision prior to scraping off meat of a bone or for cutting through the leg. With the device, the desired cutting accuracy is obtained by using mechanical positioning means which operate on the kneecap of the leg, which is preferably bended in the knee joint in its natural bending direction by bending means. The positioning means may comprise one or more supporting elements with a stop edge, which can be moved along the thigh of the leg to against the kneecap.
