A method and apparatus for controlling the tools and machine is disclosed. A first selected location on the body of a fish conveyed in the direction of its longitudinal axis engages with a first feeler and effects an impulse counter to start to count pulses of a first frequency. A second selected location on the fish body then engages with another feeler and effects the impulse counter to count pulses of a second frequency and to add these pulses to the amount of pulses of the first frequency run up between the engagement of the first spot and the engagement of the second spot. If a designated total number of pulses, which is determined upon the distance between the place of engagement of the first feeler and the location of the tool to be controlled, have run up, the impulse counter is set to give a signal to a setting element controlling a tool or a guide so that the cutting of the fish is commenced at a precise desired point on the fish body.

Method and apparatus for controlling the tools and guides of a fish

A method and apparatus for filleting fishes is disclosed. The fish are cut on their underside by pairs of belly knives and pairs of rib knives, and by pairs of back knives on their dorsal sides. Between the belly knives and the rib knives are pairs of guide strips which guide the lower tail fin on the lower belly spines. Following the rib knives, a further pair of guides are provided and beneath these guides is a conveyor which acts on the underside of the backbone. Between the belly knives and the back knives, pairs of dorsal guides are provided in overlapping relationship. These individual guides are capable of adjustment to suit the shape of the fish.

Process and apparatus for filleting fish

Apparatus for aligning and conveying fish includes four vaned wheels mounted in pairs, two upper and two lower. The upper and lower vanes move between one another in the manner of paddle wheels and the upper pair can be moved towards and away from the lower pair for varying cross section of the fish.
