Abstract
Abstract A fish guiding device is provided for guiding fish for processing in fish filleting machines particularly before and during the fish processing cut. The device includes guiding elements which engage the flanks of the fish and are spread apart by the latter in a counter-directed pivoting movement. The guiding elements are provided with a further degree of freedom in the form of a counter-directed swivelling movement about an axis extending substantially parallel to the fish path. Such movement enables the guiding elements to adapt to the flanks of the fish fed between them and positions the ventral fin in a precise position for removal even when the belly opening cut runs unsymmetrically.

Claim 1
Independent Claim
162 words
In a processing machine for processing fish having at least a backbone, fillet portions on both sides of said backbone, belly radii extending downwardly from said backbone and covered by said fillet portions, and outer flanks, processing means for cutting free said fillets from said belly radii of a fish, which means comprise a. a pair of knife means arranged essentially parallel to each other, b. a guiding device positioned in the region of said knife means for supporting the flanks of the fish and comprising guiding elements which are mounted to be pushed apart synchronously in a counter-direction to each other by said fish and c. conveyor means for moving the fish past said processing tools in a conveying direction, wherein d. said guiding elements are additionally mounted pivotally about axes aligned essentially parallel to said conveying direction of said fish, and e. means are provided for synchronising the pivoting movement of said guide elements in a counter-direction to each other.
