    Tane
    The present invention relates to a tane for use in stretching and drying mink skins, in particular male mink skins.
    A wide variety of tanneries are known for use in stretching and drying skins after furs of fur animals, such as mink. After peeling and scraping the fat side of the tan, the skins are placed with the fat side facing inwards and thus the hair side facing outwards. Taner generally has a top end and an opposite foot end and has a cross-sectional circumference that extends gradually from the top end towards the foot end. Tanks for male mink skins have at the lower end a piece with a constant cross-sectional circumference. The tubular skins are pulled on the tan from the top end so that the main end of the skin is placed at the top end of the tan and the rear end of the skin with the hind legs at the lower end of the tan. The skin is stretched and attached to the tan, after which it is dried by supplying air to the interior of the tan, which communicates with the outer surface of the tan via openings. Typically, a tan bag is placed on the tan before the skin is applied.
    A recognized standard for tanner for male mink skins is based on plate-shaped tanners, which have a constant thickness of 1 cm and which, seen in a plane perpendicular to the thickness, have a specified and substantially symmetrical shape and size about the longitudinal axis of the tan. Starting from the top of the tan, the width of the tan and thus the cross-sectional circumference gradually expands over a length of 90 cm. At this distance from the top end, the tan has a width of 11.5 cm and thus a cross-sectional circumference of 25 cm. After this, the tan has a constant width of 11.5 cm and thus also a constant cross-sectional circumference of 25 cm up to the foot end. The length of the piece with constant width and circumference has been extended sometimes in the last 10-15 years, as in 2001 it was 18 cm and the total length of the tan thus 108 cm and today is 30 cm and the total length of the tan thus 120 cm. Further elongation of the standard tan can be expected in the future due to the ever-increasing size of mink skins, especially male mink skins as a result of targeted feeding of the animals.
    Today, hollow tanes of plastic material or other non-absorbent material are increasingly used, and which from the inner cavity have openings out to the outer surfaces of the tan, so that drying air can come into contact with the fat side of the skin and / or one on the outer surface of the tan. placed tanepose.
    These tans, unlike the above-mentioned plate-shaped tans, do not have a rectangular cross-section, but rather a more oval or round cross-section. However, they are designed with a variation of cross-section as the circle from the tip end of the tan to its foot end, which is substantially in accordance with the above recognized standard. This is partly due to the fact that skins must comply with the above-mentioned standard in order to achieve an optimal price and the skin size is determined in leaps of 6 cm.
    Furthermore, tans are known whose circumference can be extended between a non-extended dimension and an extended dimension and vice versa, as well as tans whose length can be changed between a non-extended size and an extended size and vice versa.
    Mink fur is on the lower approx. 10 cm divided by an opening almost up to the nail. When the skin is placed and stretched on the toe, parts of the skin are folded in, especially around the hind legs, to close the "hole". Hereby parts of the skin overlap each other, especially with large male mink skins, which causes the drying of said overlapping area to be made more difficult, and there is a risk of deterioration of the quality of the skin by fat penetrating on the hair side. Another problem with at least certain known tanners is that it can be difficult to remove the skin from the tan after drying, as the skin shrinks during drying and thereby clings well to the tan.
    The present invention relates to a tane for use in stretching and drying mink skins, in particular male mink skins, which extends along a longitudinal axis between a top end and a foot end, and which has an upper toe part extending from the top end to the foot end with a gradually increasing outer cross-sectional circumference, in particular a substantially constantly gradually increasing outer cross-sectional circumference, which at a lower end adjoins and passes directly into an upper end of a lower tooth portion extending to the foot end.
    In order to remedy or at least reduce the above-mentioned problems with known tanners, the tan according to the invention is characterized in that the lower tooth part has a length of 30-54 cm, in particular 36-48 cm, and has a growing average percentage expansion per length unit of the outer cross-sectional circumference, which is preferably smaller for the lower tooth part than for the upper tooth part, and the average percentage increase of the outer cross-sectional circumference of the lower tooth part is in particular 0.1% -0.6% per. cm of the length of the lower toe part, such as 0.15% - 0.4% per. cm of the length of the lower tooth part, where by the average percentage increase of the outer cross-sectional circumference of the lower tooth part is meant: F = ((S-0) -100) / (L-0), where S is the largest circumference of the lower tooth part , 0 is the circumference of the lower tooth portion at its upper end S-0 is the increase of the circumference of the lower tooth portion, and L is the length of the lower tooth portion.
    This provides an increase in the cross-sectional circumference of the lower tan part, so that overlap of skin parts on the tan is avoided or reduced compared to known taners, and thereby a more efficient drying of the skin is obtained. Furthermore, it is expected that the gradual expansion of the outer cross-sectional circumference of the lower tan portion and the resulting substantially conical shape will facilitate the removal of the dried skin from the tan.
    The upper tooth part preferably has a length of 80-100 cm, in particular substantially 90 cm. Hereby the mentioned dimensions are close to or corresponding to those for a standard tane.
    The tan preferably has a total length from top to bottom of 120 cm to 144 cm, such as 126 cm-138 cm.
    The outer cross-sectional circumference of the lower end of the upper tooth part and thus the upper end of the lower tooth part may be 23-27 cm, preferably 24-26 cm and in particular substantially 25 cm. These dimensions are reasonably close to or similar to those of a standard tane.
    According to an embodiment of the invention, the outer cross-sectional circumference of the lower part is gradually increased over the entire length of the lower tooth part. This in principle results in a gradual conical increase of the lower tooth part over its entire length and thereby both a facilitation of the removal of the dry skin from the tooth and an increase in circumference in the area where the previously mentioned "hole" in the skin is closed by folding in skin parts by the placement of the skin on the tan, thereby reducing overlap in said area.
    According to a further design of the tan according to the invention, the outer cross-sectional circumference of the lower tan portion only gradually increases over a piece of its length, preferably over a piece of at least 6 cm. Said piece can have any desired length, e.g. 12, 18 or 24 cm, and advantageously be located where the above-mentioned "hole" is expected to be closed. Other parts of the lower tooth part may have a constant cross-sectional circumference.
    Thus, the lower tooth portion over a length of at least 6 cm may have gradually increasing outer cross-sectional circumference, such as substantially constant gradually-growing outer cross-sectional circumference.
    In one embodiment of the invention, the outer cross-sectional circumference of the lower tooth portion grows over at least the lower 6 cm of its length.
    Furthermore, according to an embodiment of the invention, the lower tooth part may have a piece of at least 6 cm with gradually increasing cross-sectional circumference located within the upper 30 cm of the lower tooth part, i.e. within the first 30 cm of the lower tooth part seen in the direction from the tip of the tooth towards its foot end.
    In general, the outer cross-sectional circumference of the lower toe part over at least 6 cm can be increased by 0.25% - 1.20%, such as 0.25% - 0.6%, per cm seen in the longitudinal direction of the tan. It should be noted that the above percentage increase is defined in a manner similar to claim 1. This design allows a relatively large increase in the outer cross-sectional circumference to be obtained over a relatively short section of the lower tooth portion. This can be an advantage in the area of the lower tooth part, where the previously mentioned "hole" in the skin must be closed, without skin parts overlapping each other to an inappropriate degree.
    Finally, in an embodiment of the invention, the lower tooth portion has a substantially constant cross-sectional circumference over a part of its length, such as over a first piece thereof of at least 6 cm, for example the first 18 cm or the first 30 cm of this set. in the direction from the tip of the tan towards its footing.
    The invention is explained in more detail below with reference to exemplary embodiments thereof shown in the drawing, in which
    FIG. 1 shows a plan view of a tane according to a first embodiment of the invention,
    FIG. 2 is a plan view of a tane according to another embodiment, and
    FIG. 3 is a plan view of a tane according to a third embodiment.
    The one in Figs. 1 according to the invention extends along a longitudinal axis L between a top end 5 with a rounded top 7 and a foot end 6 and comprises an upper toe part 1 and a lower toe part 2. Seen in the longitudinal direction, the upper toe part 1 extends from the top end 5 towards the foot end with gradually increasing outer cross-sectional circumference and has the length LI. Over the majority of the length of the upper tooth portion 1, the cross-sectional circumference of the upper tooth portion is substantially constantly increasing. At its lower end 8, the upper tooth part adjoins and merges directly into the upper end 9 of the lower tooth part 2, which has the length L2. The lower tooth part 2 consists of a set longitudinally upper part 3 with the length L3 and constant outer cross-sectional circumference 0, which has the same circumference as the lower end of the upper tooth part 1, and a lower part 4, which has the length L4 and seen longitudinally increasing circumference up to the foot end 6, where the outer cross-sectional circumference has the size S, which is the largest circumference of the tan. The total length LT of the tooth is the length L1 of the upper male part 1 plus the length L2 of the lower male part 2.
    The one in Figs. 1 has the following dimensions:
    L1 = 90 cm, L2 = 42 cm, as L3 = 30 cm and L4 = 12 cm, ie. tan T total length LT = L1 + L2 = 132 cm
    The circumference: 0 = 25 cm, and
    The percentage extension of the lower circumference of the lower part 4 per. cm of its length is 0.6%. Hereby:
    The circumference increase and S = 25 + 1.8 = 26.8 cm.
    The average percentage increase of the lower tooth part is therefore (26.8-25) 100 / (42-25) = 0.17% per cm.
    Referring to FIG. 1, it should be further noted that the tan shown in Fig. 1 and described above illustrates a standard tan for male mink, if the lower part 4 is omitted, the upper tan part 1 having a length L1 = 90 cm, the lower tan part 2 a length L2 = 30 cm, and a constant outer cross-sectional circumference 0 = 25 cm.
    The one in Figs. 2 has the same embodiment of the invention as in FIG. 1 shows an upper tooth part 1 with a length L1 = 90 cm, and which at its lower end 8 passes directly into the upper end 9 of a lower tooth part 2a. The outer cross-sectional circumference 0 at the transition 8; 9 between the upper and lower tooth part is also here 25 cm, and the length L2 of the lower tooth part 2a is as with the tooth shown in Figs. 1 also 42 cm. The only difference between the one in Figs. 1 and 2 is such that at the tane shown in Figs. 2, the outer cross-sectional circumference of the lower tooth part is gradually increased constantly over this entire length L2 seen from the transition between the two tooth parts towards the foot end 6. The percentage increase of the circumference is 0.17% per second. cm, i.e. the diameter S of the lower tooth part 2 at the foot end 6 is 1.8 cm. The total length of the tan is 132 cm.
    The tan according to the embodiment shown in Figs. 3 comprises an upper tooth part 1, which is identical to the upper tooth part in the two previously described embodiments and thus has a length L1 = 90 cm. At its lower end 8, the upper tooth part 1 passes directly into the upper end 9 of a lower tooth part 2b, which consists of an upper part 3b and a lower part 4b. The circumference 0 at the transition between the upper and lower tooth part is, as in the other embodiments shown, 25 cm. The upper part 3b of the lower tooth part 2b has a length L5 = 18 cm and constantly gradually increasing outer cross-sectional circumference of 0.4% per cm. Hereby the circumference S of the upper part 3b at its lower end, i.e. feed end 6, 25 + 0.4% · 18 · 25 = 25 + 1.8 = 26.8 cm.
    The lower part 4b of the lower tooth part 2b has a constant outer cross-sectional circumference over its entire length L6 of 24 cm. The average percentage increase of the cross-sectional circumference of the lower tooth portion 2b becomes (26.8-25) 100 / 25-42 = 0.17% per cm. The total length of the tan LT = L1 + L2 = 90 + 42 is thus also 132 cm here.
    The tane according to the invention is preferably a hollow tane with an oval outer cross-sectional shape and with a cavity to which air can be fed, as previously described. It is conveniently made of a non-absorbent material such as a plastic material or metal. However, the tan can also be a flatter plate-shaped tan, like the model for a standard tan.
