The invention relates to a method for cutting off the belly flaps of fish when they are open Abdominal cavity and aims to cut off safely, quickly and in the desired manner Ensure the abdominal flap even if this is done by opening the abdominal cavity and any subsequent operations have lost their firm hold.

The cutting off of the abdominal flap is today to achieve perfect goods, especially with the Production of fillets, absolutely necessary, but in particular makes it very difficult to once the abdominal cavity is open. As long as the abdominal cavity is still closed, the offers uninjured cross-section of the fish a secure hold to from the outside with guides and cutting tools to attack. Since nowadays the fish are mainly processed only when the If the abdominal cavity is open, emptied and cleaned, the loosely hanging, soft abdominal flaps do not have any Hold more to allow the editing tools to safely grasp them.

It has now been found that this problem can be solved in a simple and safe way, if you spread the abdominal flanks from the inside through guiding organs and the separation of the Abdominal flaps using the guide organs as a cutting base through externally occurring makes shearing cuts. You are not only able to keep your stomach flanks firm and secure to lead, but also by using the guiding organs as a cutting base a shearing one Carry out a cut that allows an extremely smooth cutting off of the abdominal flap. In addition, it is possible, by designing the guides accordingly, to make the cut in such a way that as desired for the different types of fish.

It is known to let a shaped body penetrate with its tip into the belly of the fish when carrying out the so-called belly strip cutting, which rests with a slightly wider part against the edge of the belly and tensions it, so that using the shaped body as a cutting base through of externally attacking cutting organs a narrow abdominal strip can be cut out by shearing. This cutting out of a narrow abdominal strip is only another way of opening the abdominal cavity through a single cut along the abdominal edge, in which the advantage is achieved that the pelvic fins are also cut off at the same time. It was therefore a method of cutting off
the ventral lobe of fish

surprising for the person skilled in the art that the process provided according to the invention succeeds in opened abdominal cavity, d. H. so if the solid cross-section of the fish has been destroyed without Tensioning the abdominal flaps, cutting them off by means of a shear cut.

The implementation of the procedure is very simple Possible, regardless of whether the meat parts with the belly flaps have already been separated from the skeleton are, i.e. are available as finished fillets, or whether they are still on the bones when the abdominal cavity is open sit. In the latter case, both abdominal flaps can be separated at the same time by a double incision will. If the fish flanks are approximately in parallel planes, the cuts are in one plane. If the flanks are spread out in planes lying at an angle to one another, the cuts are carried out with them knives inclined to each other. Finally, the flanks of the fish can also be spread out like that be that both abdominal lobes lie in one plane and you make the separating cuts to each other and can run in parallel planes to the plane of symmetry of the fish.

In the drawing, the above-described types of implementation of the method are shown schematically; it shows

Fig. 1 the separation of the belly flap in a finished fillet,

Fig. 2 the implementation of the procedure with abdominal flanks running in parallel planes,

Fig. 3 the use of knives at an angle to one another with knives at an angle to one another Abdominal flank planes,

Fig. 4 the separation of the abdominal flaps with the abdominal flanks spread out in one plane.

In Fig. 1, the fillet 1 is guided with its flank 2 by a guide member 3 so that with the help of a with the edge of the guide member 3 cooperating knife 4 of the abdominal flap 5 shearing can be cut off.

According to Fig. 2, the belly flanks 6 and 7 of the whole fish 8 are spread out with the help of guide members 9 and 10 so that they lie approximately in parallel planes. The shearing cuts are in turn carried out using the guides 9, 10 as a cutting base by two cutting members 11, 12 lying in one plane.

Fig. 3 shows how the abdominal flanks 13, 14 of the Fish 8 are so far exhausted by the guide organs 15,16 that they are in two at an angle to each other standing levels. The organs 17, 18 performing the two cuts are here also at an angle to each other.

In the embodiment according to Fig. 4, the belly flanks 19,20 of the fish 8 are spread out by the guide members 21, 22 so far that they are in a Lie level. Now the cuts can be made by cutting members 23,24 in planes, which are parallel to each other and to the plane of symmetry of the fish.

A comparison of Figs. 2 and 4 shows that in the borderline cases either the flanks or the cutting elements in one plane and either the cutting elements or the flanks in mutually parallel Levels lie.

Claims (2)

PATENT CLAIMS: 1. A method for cutting off the abdominal lobes of fish with the abdominal cavity open, characterized in that the abdominal flanks are spread out from the inside by Fühxungsorgane and the separation of the abdominal lobes using the guide organs as a cutting base is carried out simultaneously by shearing cuts from the outside. 2. The method according to claim 1, characterized in that the abdominal flanks spread out so widely be that the two abdominal lobes lie in one plane and that separate the abdominal lobes Sections run parallel to each other and to the plane of symmetry of the fish.
