Abstract: In an apparatus for the automatic turning over of fish fillets and the conveying-on of the same in a stretched position, three staggered, superimposed belt conveyors oriented and driven in the same direction and being provided as a feeding conveyor, a collecting conveyor and a stretching conveyor are used. The feeding conveyor, whose conveying surface is spaced from that of the collecting conveyor by a distance at least corresponding to the length of the largest fillet to be handled ends above the collecting conveyor in such a way that in the vertical projection between the end of the feeding conveyor and the start of the collecting conveyor a gap is left, which is bridged by the catching element arranged below the plane of the conveying surface of the latter and which is inclined with respect thereto. The collecting conveyor and the stretching conveyor are located directly above one another, but are not in contact, a deflection wedge between them being filled by a transfer roller.

Abstract: A fish filleting machine comprises a conveyor for transporting the fish tail forwards, belly filleting knives, back filleting knives, rib knives, first severing knives for the severing through of the flesh strip, and second severing knives for the severing of the fillets at the tail root of the fish. A closed guide track for the backbone of the fish is arranged between the belly filleting knives or the back filleting knives and the second severing knives. The first severing knives lie between the belly filleting knives or the back filleting knives and the rib knives and are connected with control means, which are actuated synchronously with the conveyor and bring the first severing knives into a setting crossing the guide track before and arrival of the end of the abdominal cavity of the respective fish.

Abstract: A machine for skinning fish or fish fillets of different kinds, sizes and consistency comprising a skinning roller for conveying the fish, a skinning knife, a cutting edge on said skinning knife formed by two faces, one of which being provided to press the skin of fish or fish fillets against the skinning roller and the other one forming a back face, and a catching face arranged above the back face adjacent the cutting edge and arranged to be resiliently displaceable in the conveying direction of the fish or fish fillets, for ensuring the secure feeding of the skin between the skinning roller and the presser face.
