A machine for filleting fish

A machine for filleting fish, the machine comprising:

• filleting stations,
• a conveying system configured to convey a sequence of fish in a downstream direction through the filleting stations while each fish of the sequence of fish is oriented with a back side of the fish facing in an upwards direction and with right and left sides of the fish on opposite sides of a vertical centre plane, and
• at least one width detection mechanism placed at an upstream location relative to the filleting stations and configured for detecting a width of the fish,
• wherein at least one of the filleting stations is a plane cut filleting station comprising:
• a first cutting blade arranged on one side of the vertical centre plane and configured for cutting the fish during rotation of the first cutting blade about a first rotation axis,
• a second cutting blade arranged on the opposite side of the vertical centre plane and configured for cutting the fish during rotation of the second cutting blade about a second rotation axis, and
• a gap control structure configured based on the detected width of the fish to change a gap between the first cutting blade and the second cutting blade while the fish is being cut.

A machine for filleting fish, the machine comprising:

• a conveying system configured to convey a sequence of fish in a downstream direction through at least one filleting station while each fish of the sequence of fish is oriented with a back side of the fish facing in an upwards direction and with right and left sides of the fish on opposite sides of a vertical centre plane,
• at least one filleting station arranged to cut the fish while the fish is conveyed, and
• at least one width detection mechanism placed at an upstream location relative to the filleting stations and configured for detecting a width of the fish,
• wherein the conveying system forms an endless belt on one side of the vertical centre plane, and an endless belt on the opposite side of the vertical centre plane, each of the endless belts extending between an upstream pulley and a downstream pulley, and wherein an entrance gap is defined between the upstream pulleys for receiving the sequence of fish between the first and second endless belts, the machine further comprising an entrance gap controller configured to read the detected width and to control a position of at least one of the upstream pulleys relative to the position of the other upstream pulley to change the entrance gap based on the width.
