DEVICE FOR ALIGNING FISH WITH REGARD TO THE POSITION OF THEIR PLANE OF SYMMETRY

摘要

ABSTRACT OF THE DISCLOSURE:A device for aligning fish to be handled in fish-processing machines is shown. The object of the inventionis to lead fish, especially those with approximately circu-lar cross-section to the processing tools so exactly thatthe processing can be carried out most economically, i.e.with a high yield without any danger of undersirable parts,e.g. the skeleton, remaining in the product to be used. Thedevice according to the invention handles fish whose abdominalcavity is opened. The device comprises, in a known manner,a saddlelike guide element which supports the fish in itsabdominal cavity, conveying means which engage the flanks ofthe fish being arranged on both sides of the guide element.A support surface which is formed with a concave cross-sectioncarries knives extending into the fish path and lying flushwith the support edges. These knives serve to provide slotsat the end of the abdominal cavity to reach into the tailpart so that an aligned guiding in particular of this partof the fish becomes possible.
