Abstract

Process and device for boning carcass belly pieces in which the belly piece is clamped by the part free from ribs along a line running essentially parallel to the line joining the inner ends of the ribs to each other, and the part of the belly piece containing the innermost parts of the ribs is supported, so that this part forms an internal angle of approximately 90.degree. with the other part of the belly piece containing no ribs, while the belly piece is moved along in a direction parallel to the said other part thereof and essentially at right angles to the said connecting line, and is guided through under a device which comprises a plurality of bars which, while the belly piece is being passed through the device, exert a force or blow on the meat in between the ribs so that the meat of the unsupported part of the belly piece is bent downwardly and the ribs protrude freely upwardly.

Dependent claims

Process for boning carcass belly pieces (14;

59) or similar pieces which have an inner and outer surface, part of the inner surface having on it a row of more or less encapsulated ribs (15;
59') forming the pieces of bone to be removed, and each extending inwards essentially from a side edge of the belly piece over a part of the inner surface, in which the belly piece is supported at its outer surface and between the ribs a force is exerted on the inner surface, so that the meat is bent away from the ribs and at least the outermost parts of the ribs come away from the meat, following which a force is exerted on these parts of the ribs and the meat is held fast, so that the entire ribs come away from the meat and then are removed, characterized in that the belly piece (14;
59) is held in such a way and supported at its outer surface that the side part of the belly piece, containing at least the outermost parts of the ribs lying near the said side edge, remains free whereas only the part of the belly piece containing the innermost parts of the ribs is supported, and this part forms an internal angle of approximately 90.degree. with the other part of the belly piece containing no ribs.

Device for boning carcass belly pieces (14;

59) or similar pieces which have an inner and outer surface, part of the inner surface having on it a row of more or less encapsulated ribs (15;
59') forming the pieces of bone to be removed, and each extending inwards essentially from a side edge of the belly piece over a part of the inner surface, characterized in that the device comprises a drivable conveyor (1;
35) which has fixed on it, at intervals from each other, a number of essentially plate-shaped bearing elements (3;
37) being movable in translation during the forward movement of the conveyor, and which carry at the one, leading end a clamping jaw (4;
38) hingedly connected thereto and at the other, rear end an essentially plate-shaped supporting element (5;
39) which is hingedly connected thereto and can be swung up and down, while above the conveyor a grille (21;
55) is arranged whose bars extend in the direction of movement and parallel thereto, and means (17;
55) capable of bending away the meat from the ribs and means (22;
56, 57) capable of exerting a force on the protruding ribs.
