DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method for boning carcass portions of an animal for slaughter, in particular abdominal sections on part of the inner surface of which lies a row of more or less encapsulated ribs forming the bone parts which are to be removed and which extend essentially in parallel from a lateral edge of the abdominal section inwards, each abdominal section being held in place and supported and being passed along a number of processing units, as well as to a device for performing a method of this kind.
Such a method as well as the device to be used therefor are disclosed in, for example, international Patent Application WO91/03163. In said application, it is described how, according to a very advantageous method, the ribs can be removed from abdominal sections of an animal for slaughter. However, said method is suitable, in particular, for removal from abdominal sections in which the ribs have been cut off at a considerable distance from the spine of the animal for slaughter. The ribs contained in abdominal sections of this kind therefore have a relatively small length while the cut ends of said ribs are located at the lateral edge of the abdominal section. Therefore, and because said parts of the ribs were located at a considerable distance from the spine, these ribs are relatively easily removable from the abdominal section. According to said application, the portion of the abdominal section containing the ribs may, to this end, be bent over with respect to the ribless portion of the abdominal section after the ribs have been stripped of the membranes, whereby the ribs with their cut ends are made to protrude from the respective longitudinal edge of the abdominal section. By subsequently striking back the flesh from the protruding rib ends and then keeping the abdominal section pressed under a grate while the exposed rib ends protrude above the grate, these rib parts can relatively easily be struck out of the abdominal section, either entirely or in part, by means of an element moving above the grate.
However, there are also abdominal sections which are cut from the carcass of an animal for slaughter in such a way that the spine or at least remains of the spine are present in the abdominal section. Such abdominal sections are characterised in that the ribs present therein are in general relatively long and at the same time they are more firmly encapsulated by the flesh in the region of the spine compared with the aforementioned abdominal sections which may be boned by means of the method according to the said international patent application. Because of the length of said ribs as well as the nature of their attachment to the flesh, it has proved impossible to bone an abdominal section of this kind containing part of the spine or remains thereof according to a method and device as disclosed in said international Patent Application WO 91/03163. Until now such abdominal sections were therefore only boned by hand in accordance with a relatively costly and time-consuming procedure.
The object of the invention is to provide a method and a device for boning abdominal sections, with a part of the spine or remains thereof present therein, in an expedient, efficient and fast manner. For this purpose, the method of the kind mentioned in the preamble is characterised in that in at least one (first) processing unit a cutting or pressing force is exerted on each of the ribs at a location which is at a distance from the spine or remains of the spine, by means of which force each rib is weakened at the said location, after which the abdominal section is bent over at a subsequent (second) processing unit and each rib is broken at the said location so that the abdominal section is divided into two portions which are joined to one another, namely into a first portion in which are located the part or the remains of the spine and the rib parts extending therefrom as far as the locations of fracture, and a second portion in which the remaining parts of the ribs are located. Even if this method were carried
