<p>The invention relates to a severing appliance for dividing especially deep-frozen fish. The severing appliance consists of several disc-shaped severing blades 3 which are arranged parallel and next to one another above the supporting surface 6 of a platform 1 and the peripheral margin 5 of which is arranged at such a short distance from the supporting surface 6 that the blocks 15 fed by forward-pushing means 16, 17 are for the greater part severed, with the exception of thin webs 19. For the severing of the webs 19, the severing blades are followed by severing elements 8 arranged in a stationary manner and perfectly aligned with the severing blades 3. Even in blocks of differing local hardness, such an appliance carrying out the severing operation in two stages ensures faultless transport of the severed smaller units. The severing blades used are preferably blades which taper towards the outer margin and at the outer margin are radially upset to form double collars, the outer face forming a sharp cutting edge and the severing blades consist of hardened steel at least in the region of the outer margin. Such blades can be produced at a low outlay and minimize the cutting loss.</p> |
