Abstract

The invention concerns an apparatus for removing a surface layer from fish fillets. To permit the apparatus to operate with high precision and optimal yield for a large variety of fish species it comprises an entrainer roller which serves as a conveying surface and a pressing shoe having a pressing surface spaced from the outer surface of the entrainer roller by a gap. The pressing shoe comprises a guide for an endless belt knife. Pressing means in the form of a plurality of driven pressing rollers are arranged in an area directly above the cutting edge of the knife to act on the knife as the fish fillets are processed. The pressing rollers are mounted to rotate with two degrees of freedom thus permiting them to exert pressure with maximum surface possible and reliably flatten the fish prior to its arrival at the belt knife.
