Perforated paper Fig 5. for increased air flow for drying of skin.

Apparatus Fig. 6 for making perforated paper for drying of skins.

Scope of production.

The production relates to the use of perforated paper in the process of drying skins. Paper covers the board that is inserted into the skin during the drying process.

The paper lining serves several purposes, protecting the board from soiling from the inside of the individual skin, and partly contributing to the drying of the skin by absorbing grease from it as well as ensuring a uniform flow of air throughout the skin.

This generation relates to the result of a technique in which paper has been perforated, with the aim of increasing the air flow, the wrap ensuring faster and more homogeneous drying.

As well as apparatus used in the same process, where paper is processed to be used in the drying process of skins. The appliance is mounted in connection with an appliance that processes paper used in the drying process of skins.

The perforation of paper used for drying the skin Fig. 5 has the following purpose: * To be able to achieve an increased air flow of paper (in a given gram weight per m2) compared to non-perforated paper.

* Being able to achieve air flow of a paper thickness / quality that was not possible before.

* To increase the absorption of moisture, fat, etc.

* To ensure an even distribution of air flow through the paper * To prevent moisture and grease from forming mold on the inside of the skin.

Perforation is understood to mean: a number of holes evenly distributed throughout the paper Fig. 5 and Fig. 7 no. 1 shows a cross section of a piece of paper, no. 2 shows a hole through the paper.

The apparatus Fig. 6 for making perforated paper used in the drying process of skins has the function of perforating the paper by puncturing a number of needle-like objects Fig. 6 # 2 through the paper, thereby obtaining an increased air flow.

Fig. 6 no. 5 shows a paper path through the apparatus which perforates paper, Fig. 6 no. 1 and 4 shows some rollers whose purpose is to tighten the paper.

The purpose of the tightening is to secure some uniform holes Fig 7 no 2. Fig 6 no 3 shows a cross section of the roller with spikes making the holes. The spikes making the holes in the paper can be seen in Fig 6 no 2.

Prior art.

To secure the skin, international targets have a tane Fig 8 no 4. (a tapered board) inserted into the skin, the board is stored in the skin during the entire drying process.

As the skin releases some fat during the drying process, the tan is coated with paper or a nylon bag.

Today, two different types of material are used in the drying process.

1 * Nylon material with high air flow and low absorbency Patent No. 54555-87.

2 * Relatively low pen flow and high absorbency paper.

ad2 Paper is used in 3 versions. Tote bags in shape Fig 1, Fig 8 no 1

Tote bags in rolls Fig. 3-4, Fig. 8 no. 3 Tote paper in sheets Fig. 2, Fig. 8 no. 2 The utility model protection relates to the shapes shown in the above figures.

The news consists of perforating the above formats of paper.

Tote bags in shape Figl: A finished shape bag that has the same tapered shape as the tan.

Tote bags in rolls Fig. 3-4: A straight bag where the sides are parallel, the grower must assemble the tip himself, with e.g. tape or a staple.

Tape paper in sheets Fig 2: A sheet that wraps the tan and fic. hold with a staple.

Perforated paper for increased air flow for drying leather differs from PATENT applications Nos. 0662/86, 5455/87 and 881849 at the following points:

Step 1 By being perforated, which ensures increased air flow and therefore faster and more uniform drying. The perforation allows you to use a significantly higher paper quality without compromising the important air flow.

The strong paper quality ensures that the bag, whose purpose is to absorb moisture and grease from the dried skin, obtains an even greater and faster drying than the ordinary known paper, thereby avoiding mold damage to the skin.

Item 2 The application relates, inter alia, to a Facon bag, characterized by being a finished bag having a tapered shape, thereby avoiding folding the paper at the narrow end of the tan, which is inserted into the skin, thereby saving the grower time.

Item 3 Shortened length, the application relates, inter alia, to a shape bag which is characterized by being shortened to the desired length, thereby saving the grower time by not having to shorten the bag before application to the tan.

The drying process is as follows:

After the tan Fig 8 no 4 is coated with paper Fig 5 the skin is drawn on the tan which is then hung for drying in the drying room.

In the drying room, air is blown under the paper, after which the air Fig. 7 no. 3 must be evenly distributed over the entire skin.

In the drying process itself, the following processes occur: DK 96 00208 U3

Page 3 * The skin emits grease to be absorbed by the paper, so it is important to have a quality / thickness paper that can absorb as much grease as possible. Failure to remove grease significantly increases the risk of rancidity, resulting in poorer skincare quality. a discarding of the fur.

* The function of the air flow is to remove the moisture present in the skin itself, a rapid homogeneous drying is achieved only by distributing the air volume evenly over the entire skin during the entire drying process.

Apparatus for making perforated paper used for drying skins.

The apparatus is new in that it has never been attempted to perforate paper in order to achieve increased air flow.

The technical problem to be solved.

When heavier paper grades are used, the air flow capability decreases accordingly. This reduced air flow capability increases the risk of rancidity (as described above).

In generating, the problem of low air flow at the relatively high paper quality is solved, the problem being solved by perforating the paper Fig. 5 on the entire surface of the paper.

The following is obtained from perforated paper: * Significantly increased air flow Fig 7 no 3.

* Faster drying.

* More homogeneous drying, the air is evenly distributed throughout the skin.

* The ability to use a stronger paper quality with greater absorbency without reducing the air flow rate.

* Greater air flow ensures no mold damage to the skin, mold damage occurs when air flow is too low.

The advantage of using nylon bags is obtained by virtue of the high air flow without in any way exerting any negative influence on the paper's ability to absorb moisture and grease.

Apparatus for making perforated paper, Fig. 6, which is used in the drying process which works in connection with the processing of paper for drying the skin.

The new technique.

The novelty consists in perforating paper Fig. 5, which results in a substantially increased air flow, while maintaining the strong suction capacity of the paper.

You get the benefits of known techniques without getting any of the disadvantages.

Claims (4)

DK 96 00208 U3 Page 4 The technical effect More and more is going from the use of nylon bags to paper, by paper is meant tan bags in shape, Fig 1. tan bags in rolls Figs 3, 4 (straight bags) or tan paper in sheets Fig 2. The reason is that nylon bags do not solve the problem of aspirating grease, the nylon bag cannot absorb the amounts of grease like paper. By perforating the paper, the good effect is obtained from the nylon bag in terms of air flow without adversely affecting the ability of the paper to absorb fat.
