Den foreliggende opfindelse angår en maskine til afskrabning af pelsdyrskind og omfattende en blok, som er indrettet til opspænding af skindet med fedtsiden udad og en i nærheden af blokken anbragt skrabeind-5 retning til fjernelse af fedtet fra skindet, hvorved blokken og skrabeindretningen er forskydelige i forhold til hinanden i blokkens længderetning, og skrabeindretningen består af et i det væsentlige cylindrisk, drejeligt lejret skrabeorgan, hvis centerlinie står i det 10 væsentlige vinkelret på blokken.The present invention relates to a machine for scraping fur animals and comprising a block adapted to clamp the skin with the fat side outwards and a scraping device disposed in the vicinity of the block to remove the fat from the skin, whereby the block and the scraper device are displaceable. relative to each other in the longitudinal direction of the block, and the scraper means consists of a substantially cylindrical, pivotally mounted scraper whose center line is substantially perpendicular to the block.

Ved behandling af skind fra pelsdyr, såsom mink og ræv, består et trin i behandlingen i at fjerne fedtlaget på skindets inderside. Fedtlaget, hvis tykkelse kan være op til 40 mm, fjernes normalt ved, at skindet 15 opspændes med fedtsiden udad på en konisk blok, som forskydes i længderetningen gennem en skrabeindretning, der fjerner fedtet, som derefter suges ind i en beholder.In the treatment of fur from fur animals, such as mink and fox, one step in the treatment consists of removing the fat layer on the inside of the fur. The fat layer, the thickness of which can be up to 40 mm, is usually removed by clamping the skin 15 with the fat side outwards on a conical block which is displaced longitudinally through a scraper removing the fat which is then sucked into a container.

Skrabeindretningen består sædvanligvis af et el-20 ler flere skæreredskaber af plast eller gummi, som på kappefladen er forsynet med blade, der skraber fedtet løs fra skindet. Som følge af at skæreredskaberne er relativt stive, udsættes skindet for store belastninger ved fedtfrigørelsen. Hvis skindet fx har et hul 25 eller et andet svagt sted, rives skindet let itu af skæreredskaberne. Det har endog vist sig, at hvis den relative bevægelse mellem skindet og skæreredskaberne afbrydes, ophedes skindet ofte så stærkt af friktionen mellem skindet og skæreredskaberne, at skindet går i brand.The scraper device usually consists of a plurality or several plastic or rubber cutting tools, which are provided on the cutting surface with blades which scrape the fat from the skin. Due to the relatively rigid cutting tools, the skin is subjected to large loads during fat release. For example, if the skin has a hole 25 or some other weak spot, the skin is easily torn by the cutting tools. It has even been found that if the relative movement between the skin and the cutting tools is interrupted, the skin is often heated up so strongly by the friction between the skin and the cutting tools that the skin catches fire.

30 Det er ligeledes kendt at anvende skrabeindret- ninger, der består af vibrerende knive eller metaltråde. Disse skrabeindretninger er på en vis måde mere skånsomme mod skindet end skæreredskaberne, men de har den ulempe, at de er betydeligt langsommere at ar-35 bejde med end skæreredskaberne.30 It is also known to use scraping devices consisting of vibrating blades or metal wires. These scrapers are in some ways more gentle on the skin than the cutting tools, but they have the disadvantage that they are considerably slower to work with than the cutting tools.

Det er formålet med den foreliggende opfindelse at tilvejebringe en maskine til afskrabning af pelsdyr 2It is the object of the present invention to provide a machine for scraping fur animals 2

skind, hvilken maskine er forsynet med en såvel hurtig som skånsomt arbejdende skrabeindretning. Dette sker ved, at skrabeindretningen ifølge opfindelsen består af en børste med fjedrende børsteelementer.leather, which machine is provided with a fast and gentle scraping device. This is done by the fact that the scraping device according to the invention consists of a brush with resilient brush elements.

5 Ved at man som skrabeorgan anvender en børste, opnår man en mere skånsom behandling af skindene end med et skæreredskab, uden at den hastighed, hvormed fedtet fjernes fra skindet, falder. Børsten er således lige så effektiv som skæreredskabet, men betydelig mere 10 skånsom. Det vil forstås, at børstens børsteelementer let kan bøjes, hvis de støder mod en lokal forhøjning i skindet, og at den varmedannende friktion mellem skindet og børsten er betydelig mindre end mellem skindet og et kompakt skæreredskab.5 By using a brush as a scraper, you obtain a more gentle treatment of the skins than with a cutting tool, without decreasing the speed at which the fat is removed from the skin. The brush is thus as effective as the cutting tool, but considerably more gentle. It will be appreciated that the brush elements of the brush can be easily bent if they encounter a local rise in the skin, and that the heat-forming friction between the skin and the brush is considerably less than between the skin and a compact cutting tool.

1 5 I henhold til en fordelagtig udførelsesform af opfindelsen er børstens børsteelementer anbragt i grupper, mellem hvilke der i akselretningen er langstrakte børstefrie partier. Denne udførelsesform af børsten bevirker en mere effektiv fedtfjernelse, eftersom børste-20 grupperne fungerer på samme måde som bladene på et skæreredskab.According to an advantageous embodiment of the invention, the brush elements of the brush are arranged in groups between which there are elongated brushless portions in the shaft direction. This embodiment of the brush provides a more effective grease removal since the brush groups function in the same way as the blades on a cutting tool.

Det har også vist sig fordelagtigt, at børsterne befinder sig i en sådan afstand fra blokken, at hvert børsteelement bøjes, når det berører skindet. Fedtet 25 fjernes mest effektivt, når bøjningen er relativ lille. Børsteelementerne må i ikke noget tilfælde bøjes så meget, at den frie ende er parallel med skindet.It has also been found advantageous that the brushes be at such a distance from the block that each brush member bends as it touches the skin. The grease 25 is most effectively removed when the bend is relatively small. Under no circumstances should the brush elements bend so much that the free end is parallel to the skin.

En fordelagtig udførelsesform af maskinen i henhold til opfindelsen beskrives nærmere i det følgende 30 med henvisning til vedlagte tegning, hvor fig. 1 viser blokken og skrabeindretningen set fra enden, fig. 2 viser en børste set fra enden.An advantageous embodiment of the machine according to the invention is described in more detail in the following with reference to the accompanying drawing, in which fig. 1 is an end view of the block and scraper; FIG. 2 shows a brush from the end.

Fig. 1 viser en del af en maskine til afskrab-35 ning af pelsdyrskind. Henvisningstallet 1 betegner en blok, som har et trekantet tværsnit og bliver smallere mod den ene ende. Det ikke viste skind opspændes på 3FIG. 1 shows part of a machine for scraping fur skins. Reference numeral 1 denotes a block which has a triangular cross-section and becomes narrower towards one end. The leather not shown is clamped to 3

blokken med hårsiden mod blokken og fedtlaget udad.the block with the hair side facing the block and the fat layer outward.

Uden for hver af blokkens 1 sider befinder der sig en børste 2, som har i det væsentlige cylindrisk form og kan rotere omkring centerakslen 3. Børstens cen-5 teraksel 3 understøtter en rund ramme 4, på hvis periferi der er fastgjort børsteelementer 5. Disse børster kan udgøres af plast eller naturfibre, som har en til formålet egnet fleksibilitet.Outside of each of the sides of the block 1, there is a brush 2 which is of substantially cylindrical shape and can rotate about the center shaft 3. The center shaft 3 of the brush supports a round frame 4 on whose periphery brush elements 5 are attached. Brushes can be made of plastic or natural fibers which have a suitable flexibility for the purpose.

Som det fremgår af fig. 2 er børsteelementerne 5 10 anbragt i grupper 6, som strækker sig fra den ene enden af børsten til den anden og mellem hvilke, der befinder sig børstefrie partier 7. I det på fig. 2 viste eksempel er fire børstegrupper 6, og hver gruppe har en vinkelbredde på ca. 45°. Vinkelbredden kan variere mellem 15 40 og 80°, og den er fortrinsvis ca. 60°.As shown in FIG. 2, the brush elements 5 10 are arranged in groups 6 extending from one end of the brush to the other and between which are brushless portions 7. In the embodiment of FIG. 2 illustrates four brush groups 6 and each group has an angular width of approx. 45 °. The angular width can vary between 40 and 80 °, and it is preferably approx. 60 °.

Med hensyn til børstens funktion er det fordelagtigt, hvis hvert børsteelement 5 bøjes noget, når det passerer skindet, som det er vist på den højre børstegruppe i fig. 2. Herved opnås en effektiv fjernelse af 20 fedt, som ikke ville opnås, hvis hvert børsteelement var lige eller bøjede så meget, at dets ende var parallel med skindet.As to the function of the brush, it is advantageous if each brush element 5 bends slightly as it passes through the skin, as shown in the right brush group of FIG. 2. This results in an effective removal of 20 grease which would not be achieved if each brush element was straight or bent so that its end was parallel to the skin.

Til forskel fra det ovennævnte kan børsteelementerne 5 placeres jævnt over hele rammens 4 periferi.Unlike the above, the brush elements 5 can be placed evenly over the entire periphery of the frame 4.

25 Maskinen forsynes naturligvis med det antal børster, som svarer til blokkens sideantal. Hvis blokken er rund, vokser børsternes diameter mod enderne.25 The machine is, of course, supplied with the number of brushes corresponding to the block number of blocks. If the block is round, the diameter of the brushes grows toward the ends.
