Definitions

  • the present invention relates to an apparatus for processing the flesh side of a tubular pelt, such as a mink pelt.
  • EP 2 754 722 A1 relates to a fur processing apparatus allowing for adjusting value settings for operating parameters such as speed of the mandrel, scraping pressure and length of the scraping operation. It is mentioned that the mandrel preferably has a rectangular cross section, but that mandrels with other cross sections. such as triangular or pentagonal cross section. may also be used, and that scraper rollers are arranged to match the cross section of the mandrel so as to scrape all sides of the fur when placed on the mandrel.
  • the aim is generally to exert a uniform and/or otherwise controlled scraping pressure on the entire flesh side surface of the pelt and to ensure a sufficiently effective scraping of said surface to clean it properly and at the same time ensure that the scraping is carried out as gently to the pelt so that it is not damaged. It is often a problem to obtain a sufficiently effective scraping of especially the front leg area of the pelt.
  • the present invention provides an apparatus comprising:
  • the mean length of each side is 20 % shorter than the mean length of each side of a rectangle having the same circumference.
  • the scraping rollers engage and scrape a smaller circumferential length of the pelt than is possible with scraping rollers scraping a pelt on a mandrel having a rectangular cross-section.
  • a mandrel with a pentagonal cross-section allows for designing the mandrel so that each front leg of the pelt is arranged adjacent or at a vertex to thereby obtain improved scraping of the areas at the legs, which generally are the most difficult areas to scrape properly.
  • the pelt is more easily pulled from one side to a neighboring side than in the case of a right angle an rectangle. As a result an improved scraping is obtained of pelt portion at the areas of the corners of the mandrel.
  • the first side of the pentagonal cross-section of the mandrel is an upper essentially horizontal side defining a first upper essentially horizontal side face of the mandrel, the pentagonal cross-section further comprising a second and a third downwardly and outwardly, i.e. downwardly diverging, side extending from opposite ends of the first side and respectively defining a second and a third side face of the mandrel, and a fourth and a fifth side extending downwardly and inwardly, i.e. downwardly converging, from respective ends of the second and third sides of the pentagon to meet in the vertex opposite the first side of the pentagon and respectively defining the fourth and fifth side faces of the mandrel.
  • the tubular pelt is mounted or drawn unto the mandrel to arrange the back of the pelt on the first preferably upper side face of the mandrel so that the back and the tail of the pelt are arranged on a essentially horizontal face. It is hereby easy and convenient to draw the pelt onto the mandrel and to guide the tail into the correct position. It should, however, be noted that the first side of the pentagonal cross-section and thereby the first side face of the mandrel need not be arranged essentially horizontally.
  • the mandrel has a cross-section as an irregular symmetrical pentagon.
  • the tapering of the mandrel is therefore advantageously chosen such than both the front legs of small female pelts and the front legs of large male pelts are arranged at or adjacent the corners of the mandrel between the second and the fourth side faces and the between the third and the fifth side faces.
  • the first side can be shorter than the fourth and the fifth sides of the pentagon, such as 5 to 30% shorter.
  • the second and third sides can be shorter than the fourth and fifth sides of the pentagon, such as 5 to 30 % shorter.
  • the first, second and third sides of the pentagon can have essentially the same lengths.
  • the width of the first, second, third side faces of the mandrel can advantageously be set so that the front legs of the pelt are arranged at or adjacent the vertex between the second and fourth sides and the vertex between the third and fifth sides, respectively.
  • an additional first scraping roller is arranged at the first preferably upper side face of the mandrel and is configured, during operation of the apparatus, to be engageable with and scrape the flesh side portion of the pelt superjacent the upper side face of the mandrel.
  • the portion of the flesh side of the skin arranged superjacent to the first side face will be scraped first by the primary scraping roller and thereafter by the additional scraping roller.
  • This is advantageous especially when the back of the pelt is arranged superjacent the first side face of the mandrel as the back of the pelt may be difficult to scrape properly with a single scraping roller.
  • an additional second and third scraping roller is arranged respectively at the second and third preferably downwardly diverging side faces of the mandrel and configured, during operation of the apparatus, to be engageable with and scrape the flesh side portion of the pelt superjacent the respective side faces of the mandrel.
  • the pelt portions arranged superjacent to the mentioned side faces of the mandrel are first scraped by primary scraping rollers and thereafter by the additional scraping rollers, whereby the scraping and cleaning of the flesh side of the pelt are improved.
  • This is advantageous as the front legs of the pelt can be arranged superjacent the said side faces of the mandrel.
  • an additional fourth and fifth scraping roller is arranged respectively at the fourth and fifth preferably downwardly converging side faces of the mandrel and configured, during operation of the apparatus, to be engageable with and scrape the flesh side portion of the pelt superjacent the respective side faces of the mandrel.
  • the additional fourth and fifth scraping rollers allow for an additional scraping of the portion of the flesh side of the pelt superjacent the fourth and fifth side faces of the mandrel after said side faces have been scraped by the primary scraping rollers. This is considered advantageous if the legs of the pelt are arranged at the mentioned side faces of the mandrel.
  • an optimal scraping result is obtainable by scraping all pelt portions by means of both a primary scraping roller and thereafter by means an additional craping roller.
  • the primary scraping rollers are arranged, during engagement with and scraping of the flesh side of the pelt, to rotate in the direction from the thin end towards the thick end of the mandrel, i.e. in the opposite direction of the longitudinal forward direction of the mandrel during scraping of the fur.
  • An additional scraping roller can be arranged at each of the second and third side faces of the mandrel, each scraping being configured to rotate in the opposite direction of the primary scraping rollers.
  • an additional scraping roller can be arranged at each of the fourth and fifth side faces of the mandrel and be configured to rotate in the opposite direction of the primary scraping rollers.
  • the additional scraping rollers are arranged, during engagement with and scraping of the flesh side of the pelt, to rotate in the direction from the thin end towards the thick end of the mandrel, i.e. in the opposite direction of the longitudinal forward direction of the mandrel during scraping of the fur.
  • a primary scraping roller can be arranged at each of the second and third side faces of the mandrel and be configured to rotate in the opposite direction of the additional scraping rollers.
  • a primary scraping roller can be arranged at each of the fourth and fifth side faces of the mandrel and be configured to rotate in the opposite direction of the additional scraping rollers.
  • Both the primary scraping rollers and the additional scraping rollers can be of any type of scraping rollers and can be combined in any way considered advantageous or useful.
  • the scraping rollers can be of the known types: scraping rollers with helix-shaped teeth, scraper rollers with V-shaped teeth and scraping rollers with straight teeth, or any other type of scraping rollers.
  • helix scraping roller or "helix roller” is to be understood a scraping roller where the teeth of the roller are arranged so that the starting and ending points of each tooth at the end faces of the roller are displaced from each other i.e. are positioned at different angle positions on the circumference of the roller in such a way that the teeth extend essentially helically along the roller surface, whereby the scraping roller exerts a force component on the pelt on the mandrel transversal to the longitudinal direction of the mandrel.
  • V-scraping roller with V-shaped teeth or "V-scraping roller” or “V-roller” is to be understood a scraping roller where the teeth essentially follow a V-shape between the end faces of the scraping roller.
  • the vertex of the teeth can face in the same direction as the rotation direction of the roller, whereby the pelt is forced towards the edges of the mandrel side face in question or faces in the opposite direction of the rotation direction of the roller, whereby the pelt on the respective side face of the mandrel is drawn towards the middle of said side face, the latter arrangement being the most common.
  • scraping roller with straight teeth or “straight scraping roller” or “straight roller” is to be understood a scraping roller with teeth extending essentially linear between the end faces of the roller, the end point of each tooth being at the end faces of the roller positioned essentially at the same angular position of the circumference of the roller.

  • the primary scraping roller at the second and third side faces of the mandrel is on each of said faces a helix roller pulling/forcing the pelt in the same direction transversely of the longitudinal direction of the mandrel, the direction being preferably away from the first side face of the mandrel, i.e. downwardly from the first side face.
  • the apparatus can comprise an additional scraping roller at the second and third side faces, the additional scraping roller being on each of said faces a V-roller or a helix roller optionally pulling/forcing the pelt in the opposite direction transversely of the longitudinal direction of the mandrel than the primary helix rollers, on each of said side faces, or a V-roller on the second side face and a helix roller on the third side face optionally pulling the pelt in a transverse direction opposite to that of a primary helix roller at the third side face.
  • the apparatus can be provided with the following scraping rollers at the second and third side faces of the mandrel:

  • the apparatus can comprise an additional scraping roller at the fourth and fifth side faces, the additional scraping roller being on each of said faces a V-roller or a helix roller optionally pulling/forcing the pelt in the opposite direction transversely of the longitudinal direction of the mandrel than the primary helix rollers on each of said side faces, or a V-roller on the fourth face and a helix roller on the fifth face optionally pulling the pelt in a transverse direction opposite to that of a primary spiral roller at the fifth face.
  • the apparatus can be provided with the following scraping rollers at the fourth and fifth side face of the mandrel:
  • said apparatus comprises an additional scraping roller at the fourth and fifth side faces, the additional scraping roller being on each of said faces a helix roller, the additional scraping roller at the fourth side face pulling/forcing the pelt in a direction transversely of the longitudinal direction of the mandrel, preferably in a direction opposite to that of the primary scraping roller at the fourth side face, and the additional scraping roller on the fifth side face pulling/forcing the pelt in a direction transversely of the longitudinal direction of the mandrel, the direction being in the opposite or the same direction as the primary scraping roller at the fifth side face.
  • the scraping rollers of the apparatus are arranged in a scraping roller housing comprising, as seen in the forward movement direction F of the mandrel into the housing, the following consecutive sections:
  • Figs. 1 and 2 show an apparatus 6 according to the invention for processing, i.e. scraping, the flesh side of a tubular pelt, especially a mink pelt.
  • the apparatus comprises an elongated tapering mandrel 7 having a first thin end 8 and an opposite second thick end 9. At the second thick end 9, the mandrel 7 is fixed to a carriage 10.
