This application claims priority to Danish Patent Application No. PA 201570532 filed on Aug. 17, 2015, the disclosure of which including the specification, the drawings, and the claims is hereby incorporated by reference in its entirety.
The invention relates to a pelt board for drying tubular furs such as mink furs, a drying system for drying tubular pelts, a method of drying tubular furs and use of a pelt board.
Pelt boards for drying tubular pelts such as mink furs, fox furs or the like are well known. Such pelt boards has a foot end and a tip end, and may be configured for receiving drying air at a tip end of the pelt board when a tubular fur is arranged on the pelt board with the skin side facing the pelt board. U.S. Pat. No. 824,364 and U.S. Pat. No. 3,313,038 discloses older drying systems where drying air is provided at a tip end of a pelt board. Newer pelt boards for drying tubular furs such as mink furs, e.g. as disclosed in WO 2005/026394 A1 and WO 2014/032950, may comprises an internal cavity in the pelt board for distributing drying air to ventilation openings provided at the surface of the pelt boards. Drying air is provided through an air supply inlet at a foot end of the pelt board into the cavity, and therefrom through the ventilation openings to the skin side of the fur. Such pelt boards are also capable of reducing or increasing the circumference of the pelt board dependent on the setting of a distension system of the pelt board in order to allow easier release of the tubular pelt from the pelt board after drying.
The presently available pelt board solutions, such as pelt board solutions comprising distensions systems, may however suffer from drawbacks in relation to providing drying air to the pelt board. It may thus e.g. be an object of the present invention to provide an advantageous solution for providing drying air to pelt boards.
The invention relates to a pelt board for drying tubular furs such as mink furs, wherein said pelt board comprises a foot end and a tip end, and wherein said pelt board comprises:
Hollow pelt boards with half parts enclosing an internal cavity for guiding and distributing drying air internally in the pelt board, and a distension system, comprises movable parts in the internal cavity in order to provide the distension function. Such movable parts may e.g. comprise a spear/guiding member extending into the pelt board from the foot end of the pelt board and/or other means that are adapted to e.g. displace substantially flat, longitudinal profiles arranged at the longitudinal edges of the pelt board, or to displace the half parts themselves. This necessarily takes up space inside the cavity.
There is generally little space in the cavity at the tip end of the pelt board, and the tip end of the pelt board may also suffer from being more vulnerable to external forces than the wider/larger foot end of the pelt board.
By the present invention, it is be possible to solve the space issues at the tip end of the pelt board and provide a more durable pelt board having a distension feature and an internal cavity enclosed by half parts, and which is suitable for receiving drying air from the tip end part of the pelt board during a drying process where a tubular pelt is arranged at the pelt board with the skin side facing the pelt board surfaces.
The guiding recess may provide that the air exchange part such as a rigid pipe or the like can be guided between a tubular pelt on the pelt board and the outer surface of the pelt board from the tip end of the pelt board to a suitable location. The air exchange part is thus guided in the recess along the outer surface of the pelt board to a location where space issues are reduced as the width of the pelt board may gradually increases towards the foot end of the pelt board at least at the longitudinal edges. The drying air can then be provided to (or extracted from) the internal cavity at that location through the drying air supply opening.
Moreover, the present solution may provide a more advantageous distribution of the drying air inside the pelt board cavity as the drying air is not supplied at the outmost tip end of the pelt board, but is instead supplied at a distance from the outmost tip end at the drying air supply opening in the outer surface of at least one of said half parts. The guiding recess may thus be configured to guide an air exchange part such as a pipe or the like to a position near the drying air supply opening.
The half parts provide broad outer support surfaces preferably having a plurality of elevations for supporting the skin side of the fur, which broad outer support surfaces extend between the more narrow longitudinal edges.
In aspects of the invention, said drying air supply opening may extend between the recessed surface of said guiding recess and an upper, elevated edge of said half part, which upper elevated edge is elevated compared to said recessed surface.
The drying air supply opening hereby extends in a substantially transverse direction compared to the longitudinal direction of the pelt board. The air can thus flow into the pelt board's internal cavity in the longitudinal direction of the pelt board, which may provide that more air is supplied into the cavity and/or in that the air supply is supplied more consistently towards the foot end. The drying air may hereby experience little resistance when provided into the pelt board cavity and thus, a more efficient drying air may thus be provided. This may e.g. also be advantageous if the same air supply unit such as a motor/fan combination provides drying air to a plurality of pelt boards.
Said drying air supply opening may in aspects of the invention have a height difference between the upper, elevated edge and the recessed surface between the between 1.5 mm and 20 mm such as between 2 mm and 10 mm.
In other aspects of the invention, the drying air supply opening may be provided substantially in the surface of the guiding recess and do not extend transverse to the longitudinal axis.
In preferred aspects of the invention, said drying air supply opening may be arranged away from a first plane extending through said opposite longitudinal edges and preferably also said tip end.
Preferably, said guiding recess comprises a groove or consist of a groove in the outer surface of at least one of said half part, so that the groove extends in the longitudinal direction of the pelt board.
In preferred aspects of the present invention, said guiding recess is configured to provide an opening between the recessed surface of said guiding recess and a tubular fur, when said tubular fur is arranged on the pelt board so that the air exchange part can be inserted between said recessed surface and said tubular fur after the tubular pelt is arranged on the pelt board.
This provides that the air exchange part may advantageously be provided after the tubular fur is arranged on the pelt board, e.g. stretched on the pelt board and fixed to the board by means of a holding bag, a flexible sheet of plastic or the like wrapped around the pelt board or the like. This may provide an efficient process when preparing a plurality of pelts on pelt boards for drying.
In advantageous aspects of the present invention, the length of said guiding recess is no more than ¼ of the length of the pelt board such as no more than 1/10 of the length of the pelt board, e.g. no more than 1/15 of the length of the pelt board, e.g. about 1/20 of the length of the pelt board.
This may e.g. provide that the drying air can be introduced into the interior cavity between the half parts after the space and/or strength issues at the tip end due to e.g. the tapering form of the pelt board are overcome. The drying air may hereby be provided at the half of the pelt board comprising the tip end and from here distributed towards the foot end. This may provide advantages in relation to obtain a satisfactory drying of the tubular fur.
In preferred aspects of the invention, at least one of said half part provides a curved outer profile.
In aspects of the invention, both half parts may comprise a curved outer profile extending between the longitudinal edges, but in other embodiments of the invention, at least one of the half parts may have a substantially flat profile. The guiding recess may be arranged in the surface of a half part having a flat profile and/or in the surface of a half part having a curved profile.
In preferred aspects of the invention, said pelt board may comprise a first plane extending through said longitudinal edges of said pelt board, and a second centre plane extending in the longitudinal direction of the pelt board and being substantially perpendicular to said first plane, which second plane preferably extends through said guiding recess.
In aspects of the invention where the second centre plane extends through the guiding recess the guiding recess will be arranged substantially at the middle of the pelt board from the tip end. This may provide advantages in relation to holding the pelt board while it hangs vertically from a holding arrangement to solve balancing issues and/or in order to provide a more mechanically resistant tip end part of the pelt board.
The guiding recess may in preferred aspects of the invention comprise a support surface for supporting said air exchange part such as a rigid pipe, when said air exchange part is arranged in said guiding recess between a tubular fur arranged on the pelt board, and the support surface of said guiding recess.
The air exchange part such as (preferably) a rigid pipe or a flexible hose may thus be pressed towards the support surface by the pelt and/or by a clamp or the like of a holding arrangement. This provides that the pelt board may hang freely from the tip end of the pelt board during drying.
In advantageous aspects of the invention, said distension system is configured to be operated at the foot end of said pelt board in order to either expand or collapse said pelt board, preferably by displacing a protruding part of a longitudinal member of said distension system in the longitudinal direction of the pelt board, which longitudinal member extends in the longitudinal direction of said pelt board inside said cavity.
This may e.g. provide that existing, and experientially well-functioning distension systems, may be utilized which may also fit into existing drying systems. Such systems provides e.g. that a protruding part of a longitudinal member inside the pelt board is operated at the foot end where there is more space and the pelt board may be, mechanically speaking, stronger. Also, such a protruding part may in aspects of the invention be utilised in other drying systems for providing drying air through the foot end while the pelt board stands vertically from a drying aggregate so the protruding part of the longitudinal member extends into an opening of the drying aggregate.
In advantageous aspects of the invention, said pelt board may moreover be configured for receiving drying air through a further drying air supply opening to said interior cavity at the foot end of said pelt board, e.g. by supplying air into a channel of a longitudinal member of said distension system.
Hereby, the supply of drying air may be provided either through the foot end and/or by means of the first drying air supply opening in the guiding recess at the tip end. One pelt board may thus be constructed to fit different types of drying systems and this may have advantageous environmental impacts and/or production related impacts as well as users may have more freedom of choosing and in that a reduced number of pelt board types may be produced. As the types of pelt boards and drying systems evolve, it might be advantageous for a user to not be bound by purchasing a large amount of pelt boards that needs to fit a specific drying system.
Also, if a pelt from larger skin types such as fox skins and/or special types of mink skin suffers from being more demanding to dry properly; drying air may in aspects of the invention be provided both by means of the guiding recess and through the foot end.
In aspects of the invention, said drying air supply opening at said tip end part may be oblong, such as wedge shaped, rectangular or oval, and extends in the longitudinal direction of said pelt board.
This may provide that more drying air may be provided at guiding recess, and/or that the air resistance may be reduced. As there is little space at the tip end of the pelt board, providing an oblong opening may be advantageous in order to enable a sufficient drying air supply to the internal cavity of the pelt board, while providing a sufficient mechanical strength of the pelt board at the tip end part.
The drying air supply opening may in aspects of the invention extend in a substantially transverse direction compared to the longitudinal direction of said pelt board. This may e.g. provide that the drying air can enter the internal cavity in the longitudinal direction of the pelt board.
The internal cavity of the pelt board extends in advantageous aspects of the invention between a recessed wall part providing said guiding recess and the opposing half part.
This may e.g. help to provide a sufficient drying at the tip end part of the pelt board as the air may be guided past this part of the internal cavity by the air exchange part and enter the internal cavity further towards the foot end through the drying air supply opening. The drying air can then from there move towards the tip end in the internal cavity at the tip end part to dry a part of the skin covering the guiding recess and the tip end part of the half part opposite the guiding recess supporting the air exchange part.
In aspects of the invention, a recessed wall part providing said guiding recess may be displaced from a first plane P1 extending through said longitudinal edges of said pelt board in the longitudinal direction of said pelt board, so that drying air can flow between said first plane and the inner surface of the wall part inside the cavity, and preferably so that a longitudinal member for operating the distension system can extend between said wall part and the other half part substantially in said first plane.
This may e.g. help to provide a sufficient drying at the tip end part of the pelt board, and even also provide that the distension system may provide sufficient change of the circumference at the pelt board at the tip end part in order to assure that the pelt can easily be removed from the pelt board after drying.
The invention moreover in a second aspect relates to a drying system for drying tubular pelts, where said drying system comprises one or more pelt boards according to any of the preceding claims, and one or more holding devices, each holding device comprising a holding arrangement such as a clamp for holding said pelt board so that the pelt board hangs substantially vertically from said holding device from the tip end of said pelt board, and wherein said holding device preferably moreover comprises said air exchange part such as a rigid pipe or a hose to be provided in said guiding recess from said tip end between said tubular fur and the surface of said guiding recess.
The pelt board preferably hangs vertically during drying without being supported at the foot end of the pelt board.
The invention moreover in a third aspect relates to a method of drying tubular furs such as mink furs on a pelt board, wherein said pelt board comprises:
The fixation means may in aspects of the invention comprise a holding bag or a plastic sheet wrapped around the pelt/fur at the pelt board at a holding area near the foot end of the pelt board.
In an embodiment of said a third aspect said method may comprises the step of arranging said pelt board at a holding device by means of a holding arrangement such as a clamp so that said pelt board hangs substantially vertically from said holding device from the tip end part of said pelt board.
In embodiments of said third aspect, said holding device comprises said holding arrangement and said air exchange part.
In embodiments of said third aspect, said pelt board is a pelt board according to any of claims 1-13.
The invention moreover in a fourth aspect relates to use of a pelt board according to any of claims 1-13, where a flow of drying air in the interior cavity of said pelt board is provided by means of an air exchange part, which air exchange part is inserted in a guiding recess extending towards the foot end of said pelt board from the tip end of said pelt board so that the air exchange part is placed between said tubular fur and an outer surface of said guiding recess.
The invention may moreover in a fifth aspect relate to a pelt board for drying tubular furs such as mink furs, wherein said pelt board comprises a foot end and a tip end, and wherein said pelt board comprises:
This may e.g. provide an advantageous solution in relation to providing a reliable and efficient pelt board solution that can be utilized in different drying systems.
It is generally to be understood that the pelt board according to said fifth aspect may be combined with any other suitable aspect/embodiment of the invention as described e.g. in relation to any of the first, second third and/or fourth aspect above. Moreover, it is to be understood that the pelt board in further aspects of the invention may be a pelt board according to any of claims 1-13.
Aspects of the present disclosure will be described in the following with reference to the figures in which:
The pelt board 1 comprises two half parts 4, 5 (half part 4 is illustrated in
The tubular fur 30 to be dried on the pelt board may in preferred embodiments of the invention be a mink fur or a fox fur.
The half parts 4, 5 provides an internal cavity 6 for distributing drying air internally in the pelt board 1 between the half parts 4, 5, see
In preferred embodiments of the invention, both half parts 4, 5 as illustrated in
The half parts 4, 5 may in embodiments of the invention each extend substantially from the foot end 2 to the tapered end 3, and may each be in one piece. In other embodiments of the invention (not illustrated), the half parts may be divided into two, three or more subparts which together provided the half parts providing the support surfaces with elevations 13 and ventilation openings 7 when the pelt board 1 is assembled.
A plurality of ventilation openings 7 for providing a flow of drying air between the internal cavity 6 and the outer surface of the half parts 4, 5 are provided in the half parts 4, 5, see
The pelt board 1 moreover comprises a distension system configured to reduce or increase the circumference of the pelt board dependent on the setting of the distension system. In the present example, the distension system comprises two longitudinal parts 10a, 10b extending along the longitudinal edges 11a, 11b of the pelt board.
As illustrated in
The longitudinal parts 10a, 10b can be operated in order to increase the overall circumference of the pelt board, in the present example by moving the longitudinal parts towards or and away from the second plane P2. When the longitudinal parts 10a, 10b have been arranged in an “expanded” position (As illustrated in
The moving of the longitudinal parts 10a, 10b at the longitudinal edges 11a, 11b of the pelt board 1 is preferably provided by moving the longitudinal parts 10a, 10b in the first plane P1.
The half parts 4, 5 are in preferred embodiments of the invention substantially symmetric around at least the centre plane P2, but in other embodiments of the invention, the half parts 4, 5 may not be symmetric around the centre plane P2.
The half parts 4,5 may in embodiments be connected by mechanical fastening means such as screws, a latch/notch fastening system where latches and notches are configured to interconnect and/or by means of e.g. an adhesive.
The half parts 4, 5 may thus in preferred embodiments of the invention be kept in a fixed position and are not movable relative to each other as the longitudinal parts 10a, 10b provides the collapsible function. However, in other embodiments of the invention (not illustrated), the half part of the pelt board 1 may be half shells defining arched surfaces, and the distension system of the pelt board may be arranged to move these half shells towards and away from each other, e.g. as disclosed in WO 2005/026394 A1.
In embodiments of the invention, at least one of the half parts 4 may have a substantially flat profile, in this case half part with ref 4. The other half part (in this half part 5) may have a substantially curved profile and preferably provide a half shell. In other embodiments of the invention, both half parts may have a substantially curved outer profile and form half shells having arched outer profiles.
As illustrated in
The guiding recess 8 extends substantially from the tapered end/tip end 3 of the pelt board 1 in a direction towards the foot end 2. The guiding recess 8 ends substantially at a drying air supply opening 9 to the internal cavity 6. The guiding recess 8 is arranged so that a pipe or the like can extend in between a pelt on the pelt board 1 (described in more details later on) from the tip end 3, and thus provide drying air into, or extract drying air from, the internal cavity 6 through the drying air supply opening 9.
In preferred embodiments of the invention, the drying air supply opening 9 extends in a substantially transverse direction compared to the longitudinal axis of the pelt board.
In advantageous embodiments of the invention, the length L1 of the guiding recess 8 is no more than ¼ of the length L2 of the pelt board 1 such as no more than 1/10 of the length of the pelt board, e.g. no more than 1/15 of the length of the pelt board, e.g. about 1/20 of the length of the pelt board.
In advantageous embodiments of the present invention, the drying air supply opening 9 at the tip end 3 part is oblong and extends in the longitudinal direction LD of said pelt board 1. In the present example, the longitudinal has a wedge shape, and the wedge shaped drying air supply opening tapers towards the tip end 3 of the pelt board. However, it may also be rectangular, oval-shaped or the like in other embodiments.
The length L3 of the drying air supply opening 9 may be between 1.5 cm and 20 cm such as between 2 cm and 10 cm, e.g. between 2.5 and 6 cm. The width off the opening may be between 0.5 and 5 cm such as between 0.5 and 3 cm, e.g. about 1 cm or 2 cm.
The pelt board tapers towards the tip end 3 so the foot end 2 is wider than the tip end 3 (measured between the edges 11a, 11b).
The half parts 4, 5 provide broad outer surfaces 4a, 5a which extend between the more narrow longitudinal edges 11a, 11b.
The pelt board 1 comprises a holding area HA at the foot end 2 part of the pelt board 1. The holding area HA is not necessarily of a well-defined longitudinal extend and the properties defined for the holding area, such as the cross-sectional outer contours of the two broad side surfaces being linear and convex, respectively, may also apply beyond the extend of the holding area, such as throughout the whole of the pelt board's longitudinal extend. The holding area may e.g. extend between 25-50 cm from the foot end 2 and comprise elevations for providing a holding force when e.g. a holding bag or a flexible material is provided at the outer surface of the skin around the holding area. The pelt board edges 11a, 11b tapers toward the tip end 3 from the holding area HA and/or the foot end of the pelt board.
According to an embodiment of the present invention, the pelt board may be designed to be used for mink pelts of male minks according to a US standard, for which reason the cross-sectional circumference of the pelt board at the holding area HA is in the range of 220 to 240 millimetres. According to another embodiment of the present invention, the pelt board is designed for mink pelts of male mink according to a European standard, for which reason the cross-sectional circumference of the pelt board 1 at the holding area is in the range of 242 to 260 millimetres. For pelt boards according to these embodiments, the length L1 of the pelt board from the tip end 3 to the foot end 2 thereof is preferably in the range of 120 to 160 centimetres, more preferably in the range of 125 to 155 centimetres.
According to a further embodiment of the present invention, the pelt board may be designed for use for mink pelts of female mink, for which reason the cross-sectional circumference of the pelt board at the holding area HA is in the range of 180 to 200 millimetres. For pelt boards according to this embodiment, the length of the pelt board from the tip end to the foot end thereof is preferably in the range of 100 to 130 centimetres, more preferably in the range of 105 to 120 centimetres.
According to a still further embodiment of the present invention, the pelt board 1 may be designed for use for fox pelts, for which reason the cross-sectional circumference of the pelt board at the holding area HA is in the range of 380 to 400 millimetres. For pelt boards according to this fourth embodiment, the length of the pelt board from the tip end to the foot end thereof may preferably be in the range of 170 to 200 centimetres.
The distension system comprises the longitudinal parts 10a, 10b which are configured to be operated in order to increase or decrease the overall circumference of the pelt board 1. Moreover, the distension system comprises a longitudinal member 10c in the internal cavity 6 between the half parts 4, 5, extending in the longitudinal direction LD of the pelt board 1. The longitudinal member 10c is arranged between the longitudinal parts 10a, 10b, and when the longitudinal member 10c is displaced in the longitudinal direction LD of the pelt board 1, the longitudinal parts 10a, 10b are is displaced relative to the half parts 4, 5 in a direction away or towards the second plane P2, see
This may be provided by the longitudinal member 10c comprising a plurality of wedge-shaped elements 16 configured to fit into recesses 17 in the longitudinal parts 10a, 10b as described in more details in connection to
As can be seen from
The longitudinal member 10c comprises a lower part 19 extending in the longitudinal direction LD of the pelt board from the foot end 2 of the pelt board. This part provides a part of the distension system 10 that can be operated in order to provide the displacement of the longitudinal member 10c.
The longitudinal member 10c may in embodiments of the invention comprises a lowest wedge shaped element 16a near the lower part 19. This element 16a is configured to block the foot end of the pelt board so that air is substantially only supplied at the channel 20 and thus e.g. guided more efficiently inside the pelt board in the cavity 6.
Moreover, the longitudinal member 10c may on embodiments of the invention comprise a channel 20 for guiding drying air from a drying aggregate at the foot end 2 to the internal cavity 6 in the pelt board 1. The drying aggregate (not illustrated) may comprise a top plate with openings for receiving the lower part 19 and be configured to provide drying air to the cavity 6 at the foot end 2 of the pelt board 1 through the channel 20 when the pelt board 1 is arranged vertically in the drying aggregate 1. The drying aggregate may be designed to support a plurality of self-standing pelt boards 1 arranged in the top plate and supply drying air thereto. The drying aggregate may comprise a blowing unit for providing an air flow through the said top plate.
The guiding recess 8 extends from the tapered end/tip end 3 of the pelt board 1 and towards the foot 2 end of the pelt board 1 and is formed in a half part 4. The guiding recess 8 may in embodiments of the invention comprise one or more ventilation openings 7 in the guiding recess surface 21 for supporting an air exchange part 40.
The internal cavity 6 extends in between the wall 22 providing the guiding recess surface 21 in the half part 4 and the other half part 5. The wall 22 may e.g. be displaced from the first plane P1 as illustrated so that air can be provided between the plane P1 and the lower surface of the wall 22 facing the cavity 6 and/or so that a longitudinal member 10c (see e.g.
The guiding recess 8 is configured to receive an air exchange part 40 for exchanging air in the internal cavity 6 of the pelt board 1 as illustrated in
The air exchange part comprises an inlet 43 and an outlet 42 for the drying air.
The air exchange part 40 may in embodiments of the invention be a rigid pipe such as a metal pipe or a rigid plastic pipe, but in other embodiments of the invention, the air exchange part may be a flexible hose such as a plastic hose.
The air exchange part 40 thus extends in the longitudinal direction LD of the pelt board 1 and is thus able to blow drying air into the internal cavity 6 through the Drying air supply opening 9.
The drying air supply opening 9 extends in embodiments of the invention between the recessed surface 21 of the guiding recess 8 and an upper, elevated edge 12 of the half part 4 comprising the guiding recess 8, see also
The drying air supply opening 9 may in embodiments of the invention have a height difference H1 between the upper, elevated edge 12 and the recessed surface 21 between 1.5 mm and 20 mm such as between 2 mm and 10 mm. The height difference H1 may be measured from the lower edge 26 of the opening which may be nearest the tip end 3 if the opening 9 is oblong and extends in the longitudinal direction LD of the pelt board.
The guiding recess 8 ends substantially at the drying air supply opening 9 to the internal cavity 6.
A blowing (or suction) unit 41 can thus be connected to the air exchange part 40 and thus provide a flow of drying air from the exterior of the pelt board 1, through the air exchange part into the cavity 6 where the air is distributed to the ventilation openings 7, or alternatively sucked into the cavity 6 from the ventilation openings.
It is generally to be noted that the pelt board 1 in embodiments of the invention may be configured to receive drying air in the cavity 6 by means of either a drying aggregate for providing drying air at the foot end 2 (e.g. as described previously), or by means of the drying air supply opening at the tip end 3 part of the pelt board 1. A user may thus select where to provide the drying air dependent on the suitable drying system available. In other embodiments of the invention, the pelt board may only be configured for receiving the drying air at the tip end by means of the guiding recess and the drying air supply opening 9.
In preferred embodiments of the invention, the drying air is blown into the cavity 6 by means of a blowing unit 41, e.g. comprising an electrical motor and a fan for being driven by the electrical motor to provide a flow of air into the cavity 6 through the drying air supply opening.
As can be seen in
The longitudinal distension parts 10a, 10b may in embodiments of the invention extend in the longitudinal direction LD of the pelt board 1, substantially the entire length of the pelt board such as at least 70% of the length of the pelt board, e.g. at least 80%, such as at least 90% of the length L2 (see
The pelt board 1 taper towards the tip end 3 by the edges 11a, 11b tapering towards the centre plane P2. Also, it is preferred that at least one, or both of the broad surfaces comprising the elevations 13 may taper towards the tapered towards the first plane 1 defined by the edges 11a, 11b.
The end surfaces 25 preferably extends perpendicular to the longitudinal direction LD to be able to at least partly stand on a horizontally arranged top plate of a drying aggregate as previously explained.
Preferably, the holding arrangement 51 includes a resilient clamp 51 for providing a holding force F1 towards the air exchange part 40 when displaced away from the air exchange part 40.
The clamp 51 may thus be arranged at the outside of the pelt 30 when the air exchange part 40 extends into the guiding recess 8, and thereby provide a holding force F1 so that the pelt board 1 can hangs freely and vertically from the holding device 50, by hanging from the tip end 3.
Preferably the pelt board 3 is arranged between the holding arrangement 51 and the air exchange part 40 so that the holding arrangement 51 provides the force F1 towards a half part 5 not comprising the guiding recess 8 into which the air exchange part extends.
It is generally to be understood that the outlet 42 of the air exchange part 40 may not, as illustrated, necessarily extend into the interior cavity 6 of the pelt board 1 but may instead be arranged outside the cavity during drying.
In other embodiments of the invention, the outlet 42 may extend into the interior cavity 6 during drying.
The guiding recess 8 comprises an end wall at the 26 at the distant end of the guiding recess 8 which is distant to the tip end 3. The guiding recess 8 may thus be substantially closed at the end of the guiding recess 8 distant to the tip end 3. The drying air is thus forced from the air exchange part 40 in a direction towards the first plane P1 extending through the side edges 11a, 11b (see
Generally, when the tubular pelt 30 is arranged on the pelt board 1, the pelt/fur 30 and optionally also a fat absorbing bag/tube of a paper material or the like (not illustrated) between skin side of the pelt facing the pelt board 1 and the pelt board surface may substantially prevent drying air from flowing from the guiding recess 8 and in between the elevations 13 providing in cavities between the tubular fur 30 and the outer surface of the half parts 4, 5 from the guiding recess 8. The drying air is thus forced into the opening 9. In other embodiments of the invention, the pelt board may however be designed so that a part of the drying air from the air exchange part 40 will enter into cavities forced between the elevations/protrusions 13 and the skin/fur 30, while the main part of the drying air is introduced/forced into the interior cavity 6.
A fat absorbing bag/tube may generally in embodiments of the invention be utilized between the fur 30 and the pelt board surfaces 4a. 5a.
Thus, the length of the cross-sectional outer contour 1a determined in this manner is the cross-sectional circumference of the pelt board 1 at the position of the cross-section. The cross-sectional circumference is determined when the pelt board is expanded, i.e. when the expansion means are in the expanded position. In
The half parts 4, 5 provides the internal cavity 6 for distributing drying air internally in the pelt board 1 between the half parts 4, 5, see also
One of the half parts 4 may as shown in
In general, it is to be understood that the present invention is not limited to the particular examples described above but may be adapted in a multitude of varieties within the scope of the invention as specified in e.g. the claims.
