摘要

A method and device for slitting a chicken leg (4,5) which is suspended at its ankle joints (6) from a carrier (1) that forms part of a train of carriers that are movable in a processing line that passes said device, whereby the leg comprises a drum (4) and a thigh (5) that are connected to each other at a knee joint (7), and wherein a positioning step is applied for placing the leg in a suitable position for cutting the leg. Subsequently in a stabbing step a knife (11) is brought into engagement with the leg, which stabbing step is followed by a slitting step in which the knife is moved along the leg so as to provide a slit (12) in the longitudinal direction of the leg in order to enable a subsequent deboning step of the leg. In the positioning step a first pressing organ (9) engages the leg in the vicinity of the knee joint so as to press the leg against a movable supporting surface (8) for the leg that is positioned opposite to the pressing organ, and a second pressing organ (10) engages the leg from the side so as to push the leg into a substantially straight orientation of the drum and the thigh with respect to each other.
