Abstract
Sheath for use in the drying of skins.
ABSTRACT
The sheath for use in the drying of skins or furs (1) is designed as an elongated bag and is pro-duced from a fat absorbing air-permeable material having a certain natural resiliency, e.g. non-woven fibres of polypropylene.
This provides for obtaining that the sheath (3) contrary to prior sheaths is now capable of covering the total actual length of the board (2), thereby obtaining an improved protection of the board against getting smudged by remains from the inside of the skin (1). Moreover, a more homogeneous air dispersion during the drying process is obtained and thereby also a more uniform drying of the skins.

Description
Sheath for use in the drying of s~ins.
The invention relates to a sheath or covering case to be applied in the type of s~in dryins, where the fresh s~ins or furs are arranged on a generally slightly tapered board fitting to the actual skins and adapted to pass through channels and cut-outs provided therein a supplied conditioned air current into contact with the inside of the s~ins, the sheath having the form of an elongated bag made from a fat absorbing, air-permeable material.
Such sheaths fulfill various purposes, firstly, because they protect the board against dirt from the inside of the individual s~ins and, secondly, because they contribute to drying the s~in by absorbing its fat.
Prior sheaths are made from comparatively coarse paper and are most frequently shaped as slightly coni-cal tubes surrounding the central portion of the board but not the extreme portion thereof. Said design is an indispensable consequence of the fact that paper having the necessary strength and absobing properties is not porous or air-permeable to such a degree that the air current supplied through the board can penetrate the sheath and get into contact with the inside of the skin. The cover should therefore be made shorter than the board proper with a view to laying bare some of the vent holes of the board. Air is then flown between the inside of the s~in and the outer surface of the sheath.
In order to provide reasonable venting conditions, prior sheaths typically terminate on the level of the tail head of the mounted s~in, meaning that in order to protect also the part of the board located opposite the ripped-up tail it is necessary to apply at this place a ' separate piece of "tail paper". Said piece of paper has to be ~astened separately, thereby impeding and pro-tracting the mounting procedure.

,., 1 3~ 2474 As mentioned above, one of the purposes of the sheath is to protect the board against getting smudged by flesh remains, blood etc. from the inside of the s~in. The necessary baring of the board counteracts said aim, and such baring actually causes direct con-tact between the inside of the s~in and the board. This means, on one hand, that the board gets smudged and, on the other hand, that it is necessary to clean the board after every use and this is both time consuming and more expensive.
In order to solve the problem with respect to the incomplete wrapping it is an object of internation-al patent application No. PCT/FI85~00049 (publiqhed patent specification No. W086~00091) to provide a pro-tecting bag fitting to the drying board or shapingitself therearound. This prior bag consists of two strips of paper glued together at its longitudinal sides by adhesive seam.s. With respect to the adaptation to the tapered end of the drying board the bag is further provided either with a number of secondary adhesive seams parallel to the long sides and which on inserting the drying board are over a length indivi-dually torn, corresponding to the edges of the tapered end or with an adhesive seam substantially similar to the tapered end.
Besides the productional complications impli-cated by providing secondary or shape-adapted adhesive seams, it is a drawbac~ of this design that there are flaps around the tapered end of the drying board which due to the natural stiffness of the paper have to be bent in over the tapered end prior to pulling the un-processed s~in on to the drying board. In this case where the fittiny to the drying board is effected by tearing parallel secondary adhesive seams, difficulties in pulling off the bag will moreover often occur because the bag partially adheres to the board due to adhesive remains thereon.
~3~2474 According to the above suggested design of bag t is possible to provide single-bags by unwinding from a roller on which bags of the same length and having the mentioned adhesive seams are separated by trans-verse perforations.
Inspite of the possibility of adaptat~on aimedat, the above outlined design of the bag does not glve a solution to another drawback of known sheaths con-sisting in that the sheaths are not resilient or flexible and therefore cannot easily be adapted to dif-ferent board si~es, i.e. such boards used for example for s~ins from male and female min~s. It is therefore necessary to purchase and stoc~ as many sizes of sheaths as there are sizes of boards, and every time a sheath shall be pulled on to a board it must be ensured to choose the correct size of sheath.
The sheath according to the invention differs from prior art sheaths in that the sheath is designed as a hose of uniform width and made from a soft cling-able, resilient material of substantially homogenousair--permeability and having a certain natural resi-liency, e.g. non-woven fibres of polypropylene.
Analogous to the above suggested design it is obtained that the sheath is capable of covering the entire board, due to the fact that the sheath is air-permeable per se, thereby protecting the board against getting ~mudged and ma~ing any cleaning of the board superfluous after use or at least reducing the necessity of a possible cleaning. As the sheath is actually now in contact with the entire inside of the s~in an efficient absorption of fat from the s~in is concurrently obtained. Moreover, a favourable con-sequence is that it also becomes much easier to pull off the s~in from the board after completed drying because the s~in is not in a position to adhere ~irmly to the board. By virtue of the homogeneous air-perme-, .
., . .
. .
ability of the sheath and unlike the type of paper material used in conventional sheaths as well as for the above suggested design, an improved air dispersion during the drying process is moreover obtained and thus a more uniform drying of the skins. However, the present invention entails particularly the advantage that within certain limits it is possible to make use of sheaths of only one size since the clingable, resilient and flexible sheath easily adapts to boards of varying sizes. If the width of the board is a little larger than the width of the sheath in its flaccid condition, the sheath enlarges a little while, conversely, the bag-shaped sheath forms soft folds around the board, thereby clinging closely thereto.
The clingability and the resiliency of the sheath and its hose-like form of a uniform width there is obtained the additional advantage of rationalization that the sheaths may be offered as "endless" hoses on rollers instead of either as individual sheaths or on rollers with perforations for tearing off at predetermined lengths.
In an embodiment of the sheath according to the invention single sheaths are thus obtained by cutting from a hose roller at a desired length, following which the cut-off length is closed by transverse sealing at one end. In use a suitable length of hose is unwound which is then cut off and sealed, following which it is ready for use. The closing and cutting-off may be effected in any suitable manner, and e.g. tape, staples or hot welding may be used for the sealing.
In a broad aspect, therefore, the present invention relates to a method of drying skins by mounting a fresh skin on a tapered board having gas-distribution means therein and covered by a sheath of fat-absorbing, gas-permeable material in the form of an elongate bag and passing a conditioned gas current through said means to A

In another broad aspect, the present invention relates to a skin-drying board comprising a tapered board having gas-distribution means therein and covered by a sheath of fat-absorbing air permeable material in the form of an elongate bag, wherein the sheath is of uniform width, is made from a soft, clingable, resilient material of substantially homogenous gas-permeability and covers the entire length of the board.
The invention will now be explained in more detail with reference to the somewhat schematical drawing illustrating a board on which a sheath according to the invention is mounted and a skin, but for the sake of clarity the skin is not shown on the right half of the drawing.
//~
~ . _ As it will appear a skin 1 to be dried is pulled on to a slightly wedge-shaped or tapered board 2 which, prior to arranging the skin on it, is at first covered with an elongated sheath 3 according to the invention. Board 2 made from wood has a central, continuous slit or slot 4 which from a point close to the tapered end of the board extends substantially throughout the length of the skin. Sllt 4 is in com-munication with approximately semi-c~rcular notches or cut-outs 5 provided in the narrow lateral edges of the board and extending parallel to the plane of the board. The air current is supplied as illustrated by the arrow 6 through a central tube 7 inserted through the mouth opening of the s~in and the sheath and discharges opposite slit 4. The air will then be dispersed along the board through cut-outs 5 and slit 4 proper.
Sheath 3 having the form of an elongated bag or soc~ is pulled in over the narrow end of the board and fastened after stretching close to the wide end of the board by means of pins 8 or in any other advantageous way. The -sheath is made from non-woven fibres of polypropylene and by virtue of its natural resiliency it is adaptable to the size of the actual board.
For the sake of clarity the skin is illustrated on the drawing as fittir,g loosely around the board. In practice, the s~in fits, however, tightly to board 2 and sheath 3 ir. order to obtain, on one hand, the contact with the inside of the skin that is necessary , for the sheath to effect the fat absorption and, on the other hand, because board 2 is intended to serve as stretching board. S~in 1 is in a conventional manner, not shown, secured to board 2.

other materials having similar properties, such as air-permeability, clingable resiliency and natural st1ff ness, being applicable as well.
