Definitions

  • the present invention relates to a device for cutting off paws of killed fur- bearing animals, in particular mink, the device including a paw holder with a holding block adapted to press a paw of the animal against a stop and a cutting device adapted to cut off the paw of the animal, the holding block being arranged displaceable in a first direction between a release position and a pressing position.
  • the paws of killed fur-bearing animals may be cut off in order to avoid damage to the skin during subsequent handling of the skin.
  • DK 177001 B1 discloses a device and method for cutting off paws of killed fur-bearing animals, whereby the forelegs of an animal are inserted into a suction tube so that the chest of the animal abuts an end of the tube.
  • An actuator-driven knife is arranged in the suction tube displaceable in the transverse direction of the suction tube up against a block in order to cut off the paws of the animal.
  • EP 0 894 437 A1 discloses an apparatus for skinning fur-bearing animals, in particular mink, comprising holding means from which an animal may be suspended with the hind paws, said holding means being mutually movable to stretch the hindquarters of the animal, a movable knife adapted to make a cut from one paw across the hindquarters to the other paw.
  • the device includes a paw holder with a holding block adapted to press a paw of the animal against a saw blade arranged to saw off the paw of the animal.
  • the holding block is displaced from a position allowing insertion of the paw between the holding block and the saw blade to a pressing position in which the paw is pressed against the saw blade.
  • the paws may be held during cutting and/or skinning the animal and subsequently during sawing off the paws.
  • the object of the present invention is to provide a device for cutting off paws of killed fur-bearing animals in a more efficient way.
  • the device is characterised in that the stop has the form of a rod axially displaceable in a second direction being transverse to the first direction and between an insertion position allowing insertion of the animal paw into a recess of the paw holder and a closing position in which the rod covers the recess of the paw holder.

  • the closing position is illustrated in Figs. 2 and 3, and in this position, the rod 4 covers the entrance to the recess 6 of the paw holder 2, because the rod 4 has been displaced (in the right direction in the figures) to extend along the entire recess 6.

  • the knife 9 could also be displaceable in other directions, such as in a direction being oblique to the first direction A. In order to allow insertion of an animal paw into the paw holder 2, the knife 9 should not cover the entrance of the paw holder 2, at least not when the rod 4 is in its insertion position as illustrated in Fig. 1 .

Furthermore, preferably, in the pressing position of the holding block 3, the oblique protrusion 18 may extend up between the plate- formed member 12 and the rod 4 as seen in Figs. 2 and 3.
  • the oblique protrusion 18 may, as the holding block 3 is pressed against the rod 4, press the paw in the second direction B (to the right in the figures), in under the protrusion 17 at the free end of the first leg of the at least substan- tially U-formed cut-out 1 1 , thereby providing even better grip around the paw.
  • the holding block 3 or part of it may suitably be made from polyoxymeth- ylene (POM), also known as acetal, polyacetal and polyformaldehyde, which is an engineering thermoplastic often used in precision parts requiring high stiffness. Most other parts of the device 1 may suitably be made of metal.
