Papermaking and indentation method and papermaking equipment and indentation table for implementing the method

The invention relates to a papermaking and backing method 5 for drying raw fur, in which method the backboard is coated with a moisture- and fat-absorbing material, e.g. paper, and on the backboard of which the raw fur is attached. The invention also relates to a protective bag for facilitating the papermaking of raw fur backing boards used as a drying mold. The backboards are used for drying the skins of foxes, soups, male and female minks and other small fur animals. A layer of paper 15 of suitable absorbency and porosity must be used between the backing board and the fresh fur to promote drying of the leather and to prevent the formation of mold and the adhesion of the leather to the backing board. By papermaking, it is meant herein to protect the backboard in general with any moisture and grease absorbing material.

In some cases, old 20 newspapers are used for papermaking, but nowadays the most common sheets of paper made of sulphite cellulose are 42 * 80 cm unbleached. The paperwork is done by hand by wrapping a sheet or sheets around the backboard. The wrapper is attached with tape joints. The paperwork time varies depending on the size of the 25 backboards. Two sheets of paper must be used for fox and supitan papermaking and one sheet for mink tit papering. The retreading is done as a separate work step after paperwork. By densification is meant the threading and attachment of raw fur to a paper backing board.

Some kind of paper hose or long bag may have been tried to paper the backboards. However, a flat-width tube does not facilitate or reduce paperwork, as it still requires taping to tie the bag to the board 35 by shaping it into a backboard shape. f 2 70046

The disadvantages of the current practice are the slowness of the work, the loss of material and the mold damage to the skins caused by the partial failure of the paper. In most fur farms, the papering phase is perceived as a frustrating work step in the busy work rhythm of fur-5 animals ’skinning time.

The method according to the invention provides a decisive improvement in the above-mentioned drawbacks. To achieve this, the method and the protective bag according to the invention are characterized by what is stated in the appended claims.

By using the method according to the invention and a protective bag for papermaking fur coats, the efficiency of the work step can be increased 10 times and the consumption of raw materials is reduced by 40-50% ·

The invention will now be described in detail with reference to the accompanying drawings, which show some embodiments of the invention.

The bag blank consists of two strips of paper connected to each other by an adhesive seam La 35 3. Between the edges there are several auxiliary glue seams 5> at regular intervals, which tear open as far as the backboard is inserted into the bag blank 2.

Figure 6 shows another backboard protective bag 7 according to the invention. The bag consists of two sheets of paper joined together by glue seams 8. The adhesive seams break at the tapered tip of the bag at the edge of the papers 5, leaving an opening 10 for the blowing air supply connection. The adhesive seams are shaped and dimensioned so that the support points are evenly distributed on the curved parts of the backboard and the protective bag. In this case, the paper can withstand the stress of pulling the fur on the back. 10 The bellows 9 of the bag are necessary for mechanical continuous-track production. The bags are made in a single roller web in succession, from which they can be removed one by one during the papermaking step of the sheets using a transverse tear seam. 9 Paltteista 15 is useful for drying because they can be turned against the skull side of the surface of the skin to absorb moisture and fat from this point are difficult to clean The record. It is not necessary to tape the pieces, as they * fold into the correct position during retraction.

Figure 7 shows the placement of the bag on the backboard. The tip of the backboard is first placed in the opening in the back of the bag and the board and the bag are completely nested with one hand movement. Figure 8 shows a bag-backed backboard.

In addition to the papermaking method according to the invention and the protective bag for carrying it out, the work arrangement shown in Fig. 9 is unique, in which the papermaking and indentation are performed in successive work steps on one backboard at a time. The backboard 1 is placed 30 at its rear on a support 14 which supports it slightly above the desk 15. The protective bags 7 or the bag blank !, 2 are wrapped on a roll 12 from which they are unloaded via a control device 13. The control device 13 comprises a brake I a i tt.een, in which the rod presses the paper web with its own weight, whereby it 35 cannot slip freely. The protective bag 7 is easy to pull on the backboard 1 resting on the support 14.

After threading, the protective bag 7 is cut off or detached from its tear seam 11 pouch i ket j'is * a · The raw fur is now immediately threaded onto the papered backboard 1 and fastened from above 5 to the backboard. To facilitate the threading of the raw fur, the control device 13 is trough-shaped. After this, the board 1 is turned upside down and placed further on its back on the support 145 so that the other side of the fur can be attached to the back board 1. Now the backing is completed and the next 10 back boards can be placed on the support 14 ·>
