  • the word pelt is understood to encompass pelts of minks, foxes and similar small mammals.
  • the pelts are often stretched on a pelt board, which is nowadays made of plastic.
  • the leather side of the pelt is facing the surface of the pelt board and the pelt board may in addition be provided with a fat absorbing material such as a paper bag or sleeve, which is in contact with the leather side of the pelt.

  • WO2005/080607 discloses a method and an apparatus for fastening a fur on a pelt board by the use of a stretchable wrapping foil supplied from a single foil reel.
  • the pelt will thus not be stretched in an optimal way by applying the stretching force is applied to the lower part of the pelt. It is thus an object according to the present invention to provide technologies for properly stretching of both the upper part of the pelt as well as the lower part of the pelt.
  • the stretching operation and in particular the fine tuning of the gripping mechanisms require the user to hold one hand on the pelt which the other hand is operating the user interface of the stretching apparatus.
  • This is disadvantageous in relation to the alignment of the pelt in the stretching apparatus and it would be advantageous if the user could be able to use two hands holding the pelt instead of only one hand.
  • it is an object according to the present invention to provide technologies for allowing the user to operate the stretching apparatus while keeping both hands on the pelt.
  • the wrapping operation performed by using a single stretchable wrapping foil is suffering from serious drawbacks, in particular in relation to the speed of the operation and the physical impact on the pelt board and the fixation of the pelt board by stretching the wrapping foil during the wrapping operation.
  • the non-symmetrical structure of a pelt in particular a pelt from a mink or similar skinned animal is inhomogeneous and for this reason, the difference in strength of the pelt when exposing the pelt to the stretching operation may cause bending of the pelt board, which in the first place exposes the pelt board to excessive forces and in addition, may cause an incorrect stretching of the pelt, which incorrect stretching does not establish the intended shift of the length from one class to another.
  • the stretching of the pelt may advantageously be combined with a fur processing step such as a step of brushing the fur side of the pelt, using rollers for properly orientating the hair of the pelt, or a comb for orientating the hair of the pelt in an intentional and proper orientation prior to or after the stretching of the pelt by using the pelt stretching apparatus.
  • a fur processing step such as a step of brushing the fur side of the pelt, using rollers for properly orientating the hair of the pelt, or a comb for orientating the hair of the pelt in an intentional and proper orientation prior to or after the stretching of the pelt by using the pelt stretching apparatus.
  • a stretching apparatus for stretching a pelt on a pelt board, the pelt having a substantially tubular shape defining an inwardly oriented leather side, an outwardly oriented fur side, a nose end, a rear end and a pair of front leg cavities, the pelt board defining a top end for accommodating and fixating the nose end of the pelt, a circumferential wall for facing the inwardly oriented leather side of the pelt and a base end located opposite the top end, the stretching apparatus comprising:
  • the front leg cavities arise in the pelt after skinning and cutting off the paws of the animal.
  • the front leg cavities may comprise smaller tubular pelt parts which originally covered the front legs of the animal and which are normally inverted and folded inwardly to be positioned between the leather side of the pelt and the pelt board in order for these parts to be dried out as well.
  • cavities On the outside of the pelt when mounted on the pelt board, cavities thus appear which have been designated front leg cavities.
  • the holding device is holding the base end of the pelt board in a fixated position and preferably in a vertical orientation such that the pelt board extends upwardly from the holding device and consequently, the pelt extends on the pelt board from a rear end adjacent the holding device to a nose end pointing upwardly and away from the holding device.
  • the pair of stretching members of the stretching device may be inserted into a respective front leg cavity and thus at least partially enter the leg portion of the pelt which as explained above has been inverted.
  • the pelt By moving the stretching member towards the holding device, typically downwardly, the pelt will be stretched since the stretching members will cause the leg cavities to move along with the stretching members, thereby inducing a stretching force onto the upper part of the pelt, i.e. the part of the pelt being closest to the nose end.
  • the pelt may be stretched in a non-destructive way without needing to fasten any part of the pelt and allowing air to still access all parts of the leather side of the pelt.
  • Typical forces involved are about 100-150N for achieving a proper non-destructive stretching of the upper part of the pelt.
  • the stretching members comprise cylindrical pins. Such cylindrical pins will be advantageous for entering the leg cavities and applying the stretching force in a non-destructive way.
  • the apparatus comprises a first fastening device for fastening the rear end of the pelt, the first fastening device being movable in a direction towards the holding device for stretching the pelt.
  • the lower end of the pelt is stretched simultaneously with the upper part of the pelt.
  • the stretching of the lower part of the pelt may be performed according to the prior art or as will be described further below.
  • the rear end, of the pelt is fastened to a fastening device which is then moved in a direction towards the holding device, i.e. generally downwardly.
  • the fastening device should fasten the pelt along its complete contour and not only the tail and rear legs, since otherwise the non fastened parts of the contour of the lower end will not be stretched and may on the contrary be contracted, yielding a lower price for the pelt.
  • the apparatus comprises a second fastening device for fastening a tail part extending from the rear end of the pelt, the second fastening device being movable in a direction towards the holding device for stretching the pelt. It may in addition to the above be advantageous to stretch the tail part since the tail forms part of a very dense connective tissue which extends from the tail part along the back side of the pelt to the nose part, which tissue may be capable of withstanding a larger stretching force.
  • the apparatus comprises a third fastening device for fastening and fixating the nose end of the pelt, the third fastening device being movable in a direction towards the holding device for stretching the pelt.
  • the nose end may be fixated and moved in a direction away from the holding device, i.e. typically upwardly. Since the stretching force is applied to the pelt board, the rigidness of the pelt board sets a final limit on the amount of stretching which may be applied to the pelt, since a too large stretching force will cause the pelt board to bend and any additional stretching will not stretch the pelt but further bend the pelt board. To avoid this and relieve the stress on the pelt board, the nose end may be moved in the opposite direction of the stretching force, thereby relieving the pelt board and allowing a higher total stretching force.
  • the stretching device, the first fastening device and/or the second fastening device and/or the third fastening device is/are movable by means of a pneumatic drive, a hydraulic drive or a spindle drive.
