Den foreliggende opfindelsen ang&r et apparat til udstramning af pelsdyrskind pâ tane, dvs. pâ en flad stok - fortrinsvis af træ, der anvendes til terring af pelsdyrskindet i udstrammet tilstand, og af den i indledningen til krav 1 angivne art.The present invention relates to an apparatus for tightening fur animals on the tan, i.e. on a flat cane - preferably of wood used for drying the fur animal skin in the tense state, and of the kind specified in the preamble of claim 1.
5 Efter pelsning samt efter skrabning skal pelsdyrskind, f. eks. minkskind monteres pâ flade, koniske stokke i udstrammet tilstand for intensiv tsrring i pelstsrreri forud for garvning.5 After peeling and after scraping, fur skins, such as mink skins, must be mounted on flat, tapered sticks in a tightened state for intensive drying in fur scrub prior to tanning.
Arbejdet med udstramning og montering af pelsdyrskind pâ ter-retaner har hidtil krævet en ret stor og besværlig manuel ar-10 bejdsindsats, der udgar en meget vaesentlig skonomisk belast-ning for den enkelte pelsdyravler. Der kendes ganske vist ap-parater til brug ved udstramning og montering af pelsdyrskind pâ taner, men de kendte apparater til dette formâl er behaftet med nogle ulemper, der isar knytter sig til den teknik, der 15 anvendes til at gribe fat i pelsdyrskindet for udstramning af dette pâ tanen.The work on tightening and mounting fur animals on terranes has so far required a rather large and cumbersome manual labor effort, which poses a very significant financial burden for the individual fur animal breeders. Apparatus is known for use in tightening and mounting fur animals on tans, but the known devices for this purpose are subject to some disadvantages which are particularly related to the technique used to grasp the fur animal skin for austerity. of this on the tan.
Der er sterrelsesmæssigt ret stor forskel pâ pelsdyrskindene, idet eksempelvis skindet fra en minktave er betydeligt mindre og kortere end skindet fra en voksen han-minfc. Med henblik pâ 20 at kunne anvende falles griberorganer til pelsdyrskind af va-rierende omfang og langde arbejder kendte apparater af den her omhandlede type med en gribertype, der er indrettet til at fastklemme halen af pelsdyrskindet, idet griberorganet og tanen er indbyrdes forskydeligt anordnet, sâledes at pelsdyr-25 skindet, efter pâforing pâ tanen, kan udstrammes alene ved træk i halen af pelsdyrskindet.There is a considerable difference in size between the fur animals' skins, for example the skins of a mink tave are considerably smaller and shorter than the skins of an adult male mink. In order to be able to use, cat fur gripper means of varying scope and long working known apparatus of the type of the present invention are provided with a gripper type adapted to clamp the tail of the fur animal skin, the gripper means and the tine being interchangeably arranged. that the fur animal skin, after application on the fur, can be tightened only by the pull of the tail of the fur animal skin.
Dette medferer en uens udstramning af rygsiden af pelsdyrskindet, og ofte indebærer dette, at skindet pâ bugsiden, dvs. pâ den modsatte fladside af tanen, ikke kan "nâ sammen" for kor-30 rekt placering og fiksering af pelsdyrskindet ved bugsidens bagbenspartier. Det skal nævnes, at pelsdyrskindet i udstrammet tilstand fikseres til tanen ved hjælp af hæfteklammer vedThis results in uneven tightening of the back of the fur animal skin, and often this implies that the fur on the belly side, ie. on the opposite flat side of the tan, cannot "reach together" for proper placement and fixation of the fur animal skin at the tracheal hindquarters. It should be mentioned that the fur animal skin is fixed to the tan in the tightened state by means of staples by

2 hjælp af et trykluftdrevet hæfteapparat, idet der desuden an-vendes kartonstykker til fiksering a£ udragende dele af sfcin-det, f.eks. haie og bagben.2 by means of a compressed air driven stapler, in addition using cardboard pieces for fixing protruding parts of the screen, e.g. shark and hind legs.
Opfindelsen har til formâl at angive et forbedret apparat af 5 den indledningsvis nævnte art, og ved hjælp af hvilket man pâ enkel m&de kan lsse nævnte problemer med uens udstramning af pelsdyrskindet pâ rygsiden henholdsvis pâ bugsiden af skindet.The invention has for its object to provide an improved apparatus of the kind mentioned at the outset, and by means of which one can easily solve the said problems with uneven tightening of the fur animal skin on the back side or on the bow side of the skin.
Apparatet ifslge opfindelsen er ejendommeligt ved, at griber-organet omfatter en i dette stationær griberdel, der er ind-10 rettet til at anligge mod en indvendig side af pelsdyrskindet langs et tværomrâde af dette indenfor haleroden, og en bevæge-lig griberdel, der er indrettet til fra modsatte ydre side af pelsdyrskindet at fastklemme dette mod den stationære griberdel, idet den bevægelige griberdel er betjent af en forsfcyd-15 ningscylinder, fortrinsvis en pneumatisk trykcylinder. Herved opnâs pâ enkel mâde, at udstramningen af pelsdyrskindet pâ ta-nen kan foregâ ved et jævn fordelt, ensartet træk over hele bredden af skindets rygside, sâledes at der ikke opstâr problemer med at fâ skindet til at "nâ sammen" ved skindets bug-20 side.The apparatus of the invention is characterized in that the gripper means comprises a member of this stationary gripper member adapted to abut an inner side of the fur animal skin along a transverse region thereof within the tail root, and a movable gripper member which is adapted to clamp this from the opposite outer side of the fur animal skin to the stationary gripper part, the movable gripper part being operated by a sealing cylinder, preferably a pneumatic pressure cylinder. In this way it is obtained in a simple way that the fur of the fur-skin of the fur can be effected by a uniformly distributed uniform spread over the entire width of the back of the fur, so that no problems arise in causing the fur to "reach together" at the furrow of the fur. 20 page.
I en foretrukken udfsrelsesform er apparatet ifslge opfindelsen udformet sâledes, at griberorganet omfatter en tryksâl, hvorfra den stationære griberdel, der er bredere end tryfcsâ-len, og som er indrettet til at anligge mod bagsiden af pels-25 dyrskindet langs nævnte tværomrâde af dette, er udragende, og at nævnte bevægelige svre griberdel i form af griberkæbe er betjent ved hjælp af nævnte pneumatiske trykcylinder via et System af svingarme. Herved opnâs en særlig betjeningsvenlig og optimal fastholdelse af pelsdyrskindet indenfor dets hale-30 parti langs et tværomrâde af skindet, ogsâ uden at det er nsd-vendigt at gribe om skindet i hele dets bredde, nâr blot ud-stramningstrækket er fordelt over hele bredden af skindet.In a preferred embodiment, the apparatus according to the invention is designed such that the gripper means comprises a pressure seal from which the stationary gripper part which is wider than the pressure seals and which is arranged to abut the back of the fur animal skin along said transverse region thereof. is protruding and said movable gripper member in the form of gripper jaw is operated by said pneumatic pressure cylinder via a System of swing arms. This provides a particularly easy-to-use and optimal retention of the fur animal skin within its tail portion along a transverse region of the skin, even without the need to grip the skin throughout its width, when only the stretching feature is distributed over the entire width of the fur. pelt.

Fortrinsvis er apparatet ifelge opfindelsen forsynet med en pneumatisk forskydningscylinder, hvormed griberorganet er for-bundet ved hjælp af en svingarm, der rager ind over tanen idet nævnte tryksâl er anbragt i afstand under en fri ende af 5 svingarmen og er forbundet med denne ved hjælp af en eller flere korte arme, at den bevægelige griberkæbe er svingbart ophængt pâ en kort svingarm, der modsat griberkæben er forbundet med en aksel, der er drejeligt lejret i nævnte korte arme, og som desuden er forbundet med en betjeningarm, der er for-10 bundet med den pneumatiske trykcylinder, som er anbragt pâ svingarmen. Det forskydelige griberorgan kan naturligvis ind-stilles med varierende udgangsposition - efter den aktuelle skindlængde ligesom det forskydelige griberorgan kan forefin-des i flere stsrrelser, svarende til bredden af tanen hen-15 holdsvis bredden af skindet. Yderligere opnâs en hènsigtsmæs-sig udformning af griberorganet, der kan være indrettet til befæstigelse pâ nævnte endedel af ferstnævnte svingarm pâ ud-skiftelig mâde, sâledes at tilpasning af apparatet i afhængig-hed af den aktuelle sfcindsterrelse kan foregâ ganske let og 20 hurtigt.Preferably, the apparatus according to the invention is provided with a pneumatic displacement cylinder with which the gripper means is connected by a pivot arm which projects over the tan, said pressure seal being spaced below a free end of the pivot arm and connected to it by means of one or more short arms, that the movable gripper jaw is pivotally suspended on a short swinging arm, which is opposed to the gripper jaw by a shaft pivotally mounted in said short arms, and which is furthermore connected to a control arm which is front-mounted bound with the pneumatic pressure cylinder which is mounted on the swingarm. The displaceable gripper means can, of course, be set with varying starting positions - depending on the actual skin length, just as the displaceable gripper means can be provided in several sizes, corresponding to the width of the tine and the width of the skin, respectively. Further, a convenient design of the gripper means is provided, which can be arranged for attachment to said end portion of said swivel arm in an interchangeable manner, so that adaptation of the apparatus according to the current spindle size can be carried out quite easily and quickly.
Hensigtsmæssigt er nævnte svingarm, der rager ind over· tanen modsat denne hængselforbundet med en bæreplade, der er forsky-deligt anbragt pâ forskydningscylinderen, og som har en arm-del, der rager ind under tanen i afstand fra denne, hvilken 25 armdel ved sin fri endedel er forsynet med en mod undersiden af tanen opragende pneumatisk cylinder med et stempel, der ved en fri ende er forsynet med en stetterulle, der er beregnet til at stette mod undersiden af tanen ud for tryksâlen, der ligger an mod den opadvendende side af tanen. Herved opnâs en 30 let tilkobbelbar understetning for tanen ved manuelt arbejde med tanen . f.eks. ved udglatning og arrangement af skindet ved bugsiden - dvs. med tanen roteret 180° om en langsgâende akse gennem nævnte holder for endedelen af tanen.Conveniently, said pivoting arm projecting over the tine opposite this hinge is associated with a support plate slidably disposed on the displacement cylinder and having an arm portion projecting beneath the tan away from it, which arm portion at its free end portion is provided with a pneumatic cylinder projecting towards the underside of the tan with a piston provided at a free end with a taper roller intended to abut the underside of the tan off the pressure sealing abutting the upward side of the the board. This provides an easy-to-connect support for the tan by manual work with the tan. eg. by smoothing and arranging the skin at the bow side - ie. with the tan rotated 180 ° about a longitudinal axis through said holder for the end portion of the tan.
