Definitions

  • the present invention relates to a method and a machine for the folding out of the tail part of a pelt from a furred animal, and the securing of said tail part in the stretched out position in connection with the stretching of pelts on pelt boards with the use of a taning machine comprising means for implementing a relative displacement between a distension element or a pelt board on which a pelt has been mounted, placed between holding elements and gripping elements for securing the pelt during the stretching, which is carried out by a displacement relatively between the distension element/the pelt board and the gripping elements in the longitudinal direction of the pelt board.
  • the pelts are stretched e.g. on a pelt board which is often first provided with a fat-absorbing material, the object being that the fat remaining on the leather side of the pelt is drawn into the paper during the drying, and herewith removed from the pelt.
  • the expression "taning” is to be understood as a process which consists of the following steps: the drawing of a pelt on to a pelt board, chiefly with the leather side of the pelt facing towards the surface of the board, the stretching of the pelt on the board, and the securing of the pelt in the stretched position on the board.
  • the pelt boards which have become most widespread, and which today are used by the majority of pelt producers, including mink pelts, are made of wood, and can briefly be described as a flattish piece of wood with a first broad side surface and a second broad side surface, and a first narrow side surface and a sec- ond narrow side surface, the breadth of which is significantly smaller than the breadth of the broad side surfaces, and whose one end (the foot end) is cut off at right-angles to the longitudinal axis of the board, and whose lower end nearest the foot end has a constant breadth, but hereafter gradually decreases towards a pointed but rounded end part (the front end, the nose end), and where the board has a through-going slot between the first broad side surface and the second broad side surface, said slot lying symmetrically around the longitudinal axis of the board and extending between a place near the pointed end part and at least over a half part of the length of the board.
  • the pelt board described above is a board designed for pelts from male animals, which are normally larger than pelts from female animals.
  • a pelt board designed for use in the drying of the leather side of pelts from female animals does not have a lower end where the breadth of the board is constant.
  • the "nose end" of the pelt is to be understood as that part of the pelt which has earlier covered the cranium of the animal, and in connection with taning of pelts it is that part of the pelt which is placed in/over the pointed but rounded-off end part, which can either be called the front end or the nose end of the board.
  • tail end of the pelt is to be understood as that end of the pelt where the tail sits and from where the tail extends from the lower edge of the back part, and which can apply in general to the whole circumference of the pelt in said area. In the taning of pelts, the tail end of the pelt is always placed nearest to the foot end of the pelt board.
  • the "lower end” of the pelt shall be understood to be the lower end of the back part on both sides of the area where the tail extends from the lower edge of the back part.
  • the "belly side” is to be understood as that side of the pelt where the forelegs and the hind legs are placed.
  • the expression “taned” pelt is to be understood as a pelt mounted on a pelt board, stretched and secured on the board in the stretched position.
  • the "removal" of a pelt shall be understood to be the removal from the board of a pelt which has been stretched and secured in the stretched position on the board, typically after the end of the pelt drying process.
  • the removal procedure also includes the removal of any means which have been used for securing the pelt in the stretched position on the board.
  • the fat-absorbing material which is placed on the board before the stretching of the pelt consists of a bag made of a fat-absorbing material, preferably a fat-absorbing paper with perforations, e.g. in the form of a so-called "taning bag” which will thus be lying between the wooden board and the leather side of the pelt.
  • the drying procedure or drying of pelts shall be understood to be the drying to a preferred extent of the leather side of the pelt, where experience has shown that oxidisation and attack on the pelt by mites is excluded.
  • the drying process is typically carried out by the blowing of dry air into the slot in the board via pipes inserted into the slot, where via the perforations in the walls of the taning bag the dry air is diffused out to the leather side of the pelt which is hereby dried.
  • the hitherto most used method of carrying out the taning of pelts involves the manual stretching of the pelt on the pelt board with the leather side facing the board, which is hereafter placed in a machine comprising holding elements for securing the lower end of the board which extend below that part of the board which is covered by the pelt, also after this has been stretched out on the board by the machine.
  • the gripping elements are than inserted into engagement between the leather side and the fur side respectively on the back and the belly side, after which the pelt is stretched out on the board by a relative displacement between the gripping elements and the board, after which the pelt is fastened on the board in the stretched position by the shooting-in of staples which penetrate the pelt and are anchored in the board itself.
  • taning machines which, among other things, are known from DK 169525, which discloses a taning machine comprising gripping elements and sensors which control the extent of the stretching of the pelt on the board, so that the optimal securing can take place without the staples being drawn out.
  • the ideal method for the stretching and taning of pelts will thus be that the pelt is able to be secured in the stretched position without the use of staples.
  • a method and a holding bag for securing the pelt in the stretched position during the drying where after the pelt is stretched on the board a bag is drawn over the fur side of the pelt, and where the inside of the bag is dimensioned so that by the outwardly-directed forces of the hairs are such that the grain side the pelt is pressed so much against the board that the pelt is herewith secured in the stretched position without the use of staples, which otherwise penetrate both the pelt and the board.
  • a method and a machine for the taning of pelts is known from DK 2000 01174L, where the machine is arranged with gripping elements in such a manner that it is possible for a holding bag to be drawn over a pelt which has been stretched by the machine, and where said pelt is mounted on a traditional pelt board, and where the holding elements consist of flat, tooth-shaped holding elements which engage with the back side and the belly side (leg-side) of the pelt from underneath, with the result that the holding bag can be drawn over the pelt to a level below the lower edge of the back side of the pelt.
  • a solution to this problem could be to stretch the pelts to a somewhat further degree on the pelt boards, but the known taning machines do not offer adequate facilities for a preferred stretching of the pelt on the boards, inasmuch as the known taning machines' holding elements establish a counter-hold during the stretching of the pelts along two relatively narrow engagement surfaces on the one or on each flat side of the board, the result being that the pelts, if they are stretched to a greater extent, will be damaged in the holding areas, which are also the most valuable parts.
  • the further development consists in making the broad sides of the distension elements/pelt board convex/concave in rela- tion to the centre axis of the board, whereby a better counter-hold force is achieved in those areas of the stretched pelt which with the traditionally used pelt boards are known to slip.
  • the folding out of the tail part in connection with the taning procedure, and the securing of same in the folded out position, is thus important for being able to maintain the progress already made with the more modern methods for the taning of pelts.
  • the folding out of the tail part is thus a procedure carried out manually, where the tail is folded out after the pelt has been mounted on the board, first by the folding out the tail part and subsequently, with the use of wooden pelt boards and staples, the securing of the tail part to the board by means of one or more staples.
  • the securing of the tail part in the folded out position, and the stretched pelt in the stretched position on the distension element is carried out by the drawing of a holding bag over the pelt.
  • the holding elements for the distension element/the board and/or the means of implementing the relative displacement between the gripping elements and the distension elements/the board and/or the gripping elements can be given a vibrating movement in connection with the stretching of the pelt on the distension element/the board by implementing a displacement respectively between the distension element/the board and the gripping elements in the longitudinal direction of the board.
  • the pelt is stretched in a particularly effective man- ner, and at the same time that the tail part is both folded out and stretched, in that this is secured by the drawing-over of a holding bag which is led over the fur side of the pelt and down for the covering of the tail part.
  • a taning machine for the execution of the method according to the invention comprising at least first holding elements for the fastening of a distension element or a pelt board on which a pelt is mounted, and at least a first set of gripping elements which can be activated for securing the back of the pelt, and/or a second set of gripping elements which can be activated for securing the leg side of the pelt, and means for the implementation of a relative dis- placement in the longitudinal direction of the board respectively between the holding elements for fastening the board and the first and/or the second set of gripping elements for stretching of a pelt which beforehand has been mounted loosely on the distension element/the board, is characterised in that it comprises a tail part folding-out element consisting of a tail guide in the form of an elongated element placed between, but outside the area of action for the first set of gripping elements, where said tail guide is oriented substantially parallel with the longitudinal axis of the distension element/the board, a counter-

Abstract

L'invention concerne le tannage des peaux avant leur séchage en position étirée sur des tables ou des éléments de distension, l'accent étant mis ici principalement sur les dimensions et la qualité des peaux. Par conséquent, la présente invention porte plus précisément sur la partie de la queue de la peau qui, pour des raisons de dimensions, n'a jusqu'ici pas présenté de grand intérêt. Cependant, il est nécessaire de s'assurer que la partie de la queue de la peau soit séchée de manière adéquate afin de compenser l'oxydation ou l'attaque par des mites qui peut s'étendre à toute la peau. La présente invention concerne donc un procédé destiné au dépliage de la partie de la queue de la peau lors de l'étirage de la peau sur des tables ou des éléments de distension, ainsi qu'une machine destinée à la mise en oeuvre de ce procédé.
