The invention is intended to accelerate the papering of drying boards, to decrease wastage of material, and to avoid the mildew damage caused to furs by imperfect papering. According to the invention, papering is done by inserting a protective bag (7), made of paper or some other moisture and fat absorbing material and shaped analogously to the drying board, or a protective bag form (2) which shapes itself analogously to the board, around the drying board. The invention also concerns the protective bags and other equipment intended for application of the method.

Description

Papering and drying board insertion method, protective bag, and other equipment for implementing the method
The present invention concerns a papering and drying board insertion method for drying undressed furs, according to which method the drying board is covered with a moisture and fat absorbing material such as paper, the undressed fur being fastened around said drying board. The invention also concerns a protective bag intended to make easier the task of papering the drying boards used as drying molds for undressed furs. Drying boards are used in drying furs of fox, raccoon, male and female mink and other small fur animals. Between the drying board and the fresh fur skin, a paper layer of suitable absorption capacity and porosity must be used in the drying process in order to enhance the drying of the skin and to prevent mildew buildup and sticking of the skin to the drying board. "Papering" here refers to the protection of the drying board in general, with whatever moisture and fat absorbing material.
In some cases, old newspapers are used in the papering; however, today sheets of paper 42*80cm in size, manufactured of sulfite cellulose, are mostly used. Papering is done manually by wrapping a sheet or sheets around the drying board. The wrap is attached with adhesive tape. The time needed for the papering varies according to the size of the drying board. The papering a fox or raccoon boards requires the use of two sheets of paper, that of a mink board, one sheet. The drying board insertion is done in a separate work phase after the papering. "Drying board insertion" refers to slipping the undressed fur around a papered drying board and fastening it to said board. Some type of paper hose or long bag may have possibly been tried out in the papering of drying boards. However, a hose of even breadth does not facilitate papering nor decrease the amount of papering to be done, as it still requires taping to adhere the bag to the board by shaping it analogously to the shape of the board. The drawbacks in the current method are time- consuming operation, material wastage, and mildew damage in skins caused by partially imperfect papering. On most fur farms, the papering phase is felt to be a frustrating work phase in the time-pressured operational rhythm during the skinning period.
With a method in accordance with the invention, a decisive improvement regarding the drawbacks mentioned can be realized. In order to achieve this, the method in accordance with the invention is characterized by what is presented in the enclosed Claims.
By using, in the papering of fur boards, a method in accordance with the invention and a protective bag, the efficiency of the work phase can be increased tenfold and raw material consumption decreased by 40-50 per cent.
In the following, the invention is described in detail, and reference is made to the appended Figures, which show some applications of the invention. Figure 1. Drying board. Figure 2. A protective bag form in accordance with the invention. Figure 3. Placement of the protective bag form around the drying board. Figure 4. A papered drying board. Figure 5. Schematic of one possible operational arrangement when papering is done using a protective bag in accordance with the invention. Figure 6. Another type of protective bag in accordance with the invention. Figure 7. Placement of the protective bag around the drying board. Figure 8. A papered drying board. Figure 9. Schematic of what is considered the optimum operational arrangement for papering and drying. Shown in Figure 1 is a schematic of the drying board (1) used in drying furs, to which board are machined cavities and grooves intended to improve circulation of drying air. Shown in Figure 2 is a protective bag form (2) in accordance with the invention. The bag form consists of two strips of paper adhered against each other with an adhesive seam (3) . Between the edges, there are several equidistant secondary adhesive seams (5) which tear open for the length of the drying board pushed inside the bag form (2) .
Shown in Figure 6 is another type of protective bag (7) in accordance with the invention. The bag consists of two sheets of paper joined one agaist the other with the help of an adhesive seam (8) . The adhesive seams stop at the end of the peaked end of the bag such that the opening (10) for blowing in air is left between them. The adhesive seams are formed and measured so as to distribute the support points evenly on the curved sections of the drying board and the protective bag. Thus the paper is able to withstand the strain caused by pulling the fur around the board. The laps (9) of the bag are necessary in machine-operated continuous manufacture. The bags are manufactured as a continuous series that can be wrapped on a roll for removal one at a time during the papering phase of the drying boards, utilizing the transverse perforations. The lips (9) are useful in the drying process as they can be turned against the skull side of the fur for absorption of moisture and fat from this area which it is hard to clean properly in the skinning phase. Taping of the lips is not necessary, as they are folded into the correct position in connection with the drying board insertion.
Shown in Figure 7 is the placement of the bag around the drying board. The tip of the drying board is first inserted into the opening at the back of the bag and then, with a single movement of the arms, the board is placed completely inside the bag. Shown in Figure 8 is a drying board protected with a bag.
In addition to the papering method in accordance with the invention and the protective bag meant for its implementation, the operational arrangement shown in Figure 9 is unique; in it, papering and drying board insertion are carried out as successive work phases on one drying board at a time. The back section of the drying board (1) is inserted into the holder (14), which supports it slightly above the surface of the workbench (15). The protective bags (7) or bag forms (2) are wound on roll (12), from which they are discharged via the guidance apparatus (13). The guidance apparatus (13) includes a braking device, in which a bar presses the paper track with its own weight, thus preventing the track from freely sliding out. It is easy to pull the protective bag (7) around the drying board (1) which is supported by the holder (14). After the insertion, the protective bag (7) is cut loose or detached with the help of the perforation (11) from the chain of bags. The undressed fur is then immediately slipped around the papered drying board <1) and its upper side is fastened to the drying board. In order to facilitate the slipping phase of the undressed fur, the guidance apparatus (13) is grooved. After this, the drying board (1) is turned upside down and again its rear section is inserted into the holder (14) so as to make it possible to fasten the other side of the fur to the drying board (1). Now, the drying board insertion .has been completed and the next drying board can be placed into holder (14).
