Description

FIELD OF THE INVENTION

The present invention relates to a method and an apparatus for removing a pelt-retaining device from a pelt board on which the pelt has been retained by the pelt-retaining device during drying of the pelt.
After skinning and scraping of the flesh side of pelts, such as mink pelts, the pelt is mounted on a pelt board and frequently longitudinally stretched and thereafter fixed or retained to the pelt board in order to maintain the increased the length of the pelt during drying of the pelt. Frequently, a bag or sleeve of a fat-absorbing material, such as paper, is arranged on the pelt board prior to mounting and stretching the pelt on the pelt board.

BACKGROUND OF THE INVENTION

A traditional pelt board is a flat board of wood or a similar suitable material having parallel first and second major sides and lateral sides which are essentially parallel at the lower part of the pelt board and taper inwardly at the upper part of the pelt board. The pelt is, in the stretched state, fixed to the pelt board by means of staples at the lower end or tail end of the pelt.
Today, most pelt boards have convex major sides provided with openings and are additionally circumferentially expandable, thereby allowing an easier removal of the pelt from the pelt board after drying.
Different retaining or fixing methods and means have been proposed for retaining the pelt to the above pelt boards after stretching of the pelt.
EP 1 285 094 B1 discloses a method where a sleeve with a shape corresponding to the pelt board with the pelt mounted and stretched is drawn down over the pelt into tight contact with the fur side of the pelt for fixing the pelt to the pelt board. The sleeve can be removed by cutting it longitudinally.
EP 1 723 262 B1 discloses a method where the pelt is secured to the pelt board by winding the lower end of the pelt with a winding material, such as band, after stretching of the pelt. The winding can be removed by cutting it transversely.
EP 3 034 630 A1 discloses a fixing device for surrounding and fixing a pelt to a pelt board after stretching of the pelt comprising a radially inner expandable part partially surrounded by an outer fixed part, the expanded part including at least one filler neck allowing for filling the expandable part for fixing the pelt to the pelt board. The fixing device can be deflated and removed from the pelt board and reused.
EP patent application No. 18162047.7 , which has not been published prior to the filing date of the present invention, discloses a reusable pelt-retaining device of a type being removable by means of the method and apparatus of the present invention.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a method and an apparatus allowing for reliably removing a pelt-retaining device of the above type, especially a reusable pelt-retaining device from a pelt board
The present invention provides a method for removing a pelt-retaining device from a pelt board on which a pelt, especially a mink pelt has been retained by the retaining device during a drying process, the pelt board having a longitudinal board axis, a longitudinal middle plane, a lower end, an opposite upper end and a first major side and an opposite second major side and a first lateral side and an opposite second side,
the pelt retaining device comprising a first elongated element and a second elongated element, each having a length, a width and a thickness, an inner surface and an opposite outer surface and a first longitudinally outer end portion and an opposite second longitudinally outer end portion,
the elongated elements being elastically bendable and arranged opposite each other on respective major sides of the pelt board and bent to bring the respective inner surfaces in retaining engagement with the outer surface of the pelt and retain the pelt on the pelt board, opposite outer end portions of each of the elongated elements extending beyond the first and the second lateral side of the pelt board, and
adjacent outer end portions of the elongated elements being mutually connected by means of a ratchet-pawl means arrangement comprising a ratchet bar with a plurality of teeth being provided at and being integral with one of the outer end portions and a pawl means being provided at and being integral with the other one of the adjacent outer end portions,
the method comprising the following steps:

a. arranging the lower end of the pelt board with the pelt retained thereon by means of the retaining device in a pelt board-holding device,
b. bringing a gripping member into engagement with the outer surface of each of the elongated elements arranged opposite each other on respective major sides of the board,
c. applying a pressure to the outer surface of each of the outer end portions of the elongated members being provided with a ratchet bar in order to bring the ratchet bar out of engagement with the pawl means,
e. moving the gripping members being in engagement with the respective elongated members away from the pelt on the pelt board, thereby removing the elongated members from the pelt, after the pressure on each of the outer portions of the elongated elements have been released

When a pressure is applied during step c to the outer end portions of the elongated members being provided with a ratchet bar, the ratchet bar flexes inwardly away from and out of engagement with the pawl means.
According to an example of a method of the present invention, the pelt board is arranged in an upright position in step a.
According to an example of the present invention, the method comprises the following steps in connection with or after step c:

Step c1: applying a pressure to each of the outer end portions of the elongated members being provided with a pawl means, and
step c2: releasing the pressure on each of the outer end portions of the elongated members being provided with a pawl means, and
step c3: releasing the pressure on each of the outer end portions of the elongated members being provided with a ratchet bar.

When a pressure is applied during step c1 to each of the outer end portions of the elongated members being provided with a pawl means, the pawl means flexes outwardly away from and out of a possible engagement between a tooth of the ratchet bar.
When the pressure on the outer end portions of the elongated elements has been removed, the elongated elements can be removed by means of the gripping members being in engagement with respective elongated members as stated in step c.
According to a further example of the present invention, the method comprises applying a pressure to the outer free end of the ratchet bar in a direction towards the longitudinal board axis bar in order to bring the ratchet bar out of engagement with the pawl means.
Thereby, the ratchet bar flexes inwardly away from the engagement with the pawl means providing for a movement of the ratchet bar in a direction bringing the ratchet bar out of engagement with the pawl means.
According to an example, the method according to the present invention comprises the following step subsequent to (following) step e:
Step f: removing the pelt from the pelt board.
The pelt can be removed from the pelt board by gripping or clamping the pelt for example in the head area thereof and optionally also in other parts of the pelt and pulling the pelt upwardly towards and away the upper end of the pelt board. Additionally, and or alternatively, the pelt board-holding device can be moved downwardly.
According to a further example, the method according to the present invention comprises the following step subsequent to step e:
Step g: delivering the elongated elements of the retaining device to a retaining device store, such as a retaining device magazine.
The retaining device store can be a simple store, in which the elongated elements are oriented and positioned randomly. For reuse of the elongated elements, it is thereafter necessary or appropriate to arrange them with the desired orientation. This is especially the case when the first and second elongated elements are not identical, and one of the elongated elements is provided with a ratchet bar at each opposite end and the other elongated element is provided with a pawl means at each opposite end. It is preferred that the elongated elements are identical, having a ratchet bar at one outer end and a pawl means at the opposite outer end.
According to a further example, the elongated elements are delivered to and stored in the magazine in pairs corresponding to the pair of elongated elements forming the retaining device being removed from the retaining engagement with the pelt on the pelt board.
Thereby, the elongated elements are advantageously stored and arranged with an orientation ready for reuse
According to an example, the pairs of elongated elements are identical elongated elements stored in the magazine in positions where a ratchet bar of one of the elongated elements is placed opposite the pawl means of the other one of the pairs of elongated elements.
According to a further example, the elongated elements are stored in the magazine in a shape corresponding to the shape of the elongated element before being elastically bent to bring the respective inner surfaces thereof in retaining engagement with the outer surface of the pelt and retain the pelt on the pelt board.
In this way, the elongated elements will be moved back to assume their original shape if they do not flex back from their bent shape immediately after being removed from the pelt board
Additionally, the present invention provides an apparatus for removing a pelt-retaining device from a pelt board on which a pelt, especially a mink pelt has been retained by the retaining device during a drying process,

Reference is made to Figs. 1 and 2 disclosing an embodiment of an apparatus 1 according to the invention for removing a pelt-retaining device 2 from a pelt board 3 on which a mink pelt 4 is retained by means of the pelt-retaining device 2.
The pelt board 3 has a longitudinal board axis LA, a lower end 6 and an opposite upper end 5, a first major side 7 and an opposite second major side 8, a first lateral side 9 and an opposite second lateral side 10 and a middle plane extending through the board axis LA and through the lateral sides 9,10. The lower end 6 of the pelt board 3 is fixed in a pelt board-holding device, not shown, to arrange the pelt board in an upright position.
The pelt retaining device 2 comprises a first elongated element 12 and an identical second elongated element 12, each having a length, a width and a thickness, an inner surface 13 and an opposite outer surface 14 and a first longitudinally outer end portion 15 and an opposite second longitudinally outer end portion 16, see Fig.7 disclosing the elongated element 12 in a bent state.
The elongated elements 12 are elastically bendable and arranged opposite each other on respective major sides 7,8 of the pelt board 3 and bent to bring the respective inner surfaces 13 in retaining engagement with the outer surface of the pelt and retain the pelt on the pelt board 2, opposite outer end portions 15,16 of each of the elongated elements extending beyond the first and the second lateral side 9,10 of the pelt board 2.
Adjacent outer end portions 15,16 of the elongated elements 12 are mutually connected by means of a ratchet-pawl arrangement comprising a ratchet bar 17 with a plurality of teeth 11 being provided at and being integral with one of the outer end portions 15 and a pawl means 18 being provided at the other one of the adjacent outer end portions 16. It should be noted that the elongated elements are straight in their original state before being bent except from the ratchet bar 17 and the pawl means 18.
Each elongated element 12 is on the outer surface 14 thereof provided with a handle part 20 arranged essentially centrally of the elongated element and protruding from the outer surface 14. As seen in Fig. 7, the handle part 20 comprises a centrally arranged and transversely extending rib 21 with a lateral wedge-shaped through-going notch. A T-shaped portion 23 of the handle part 20 extends outwardly beyond the outer surface 14 at the upper edge of the rib 21 and ends in the crossbar 24 of the T.
Reference is further made to Figs. 1- 3 and Figs. 3a - 3e and Fig. 4 and the apparatus of the invention is now described in more detail. The apparatus 1 comprises an essentially C-shaped housing 25 comprising a first housing part 26, an opposite second housing part 27 spaced from the first housing part and a third housing part 28 connected to the first and second housing parts at first ends thereof. The opposite second ends of the first and second housing parts 26.27 define an opening to allow passage of the pelt board 2 therethrough and into the space 29 between the first and the second housing parts. The first and second housing parts are spaced to accommodate the pelt board fastened in the pelt board-holding device with the pelt-retaining device 2 retaining the pelt 4 on the pelt board and the elongated elements 12 of the retaining device facing respective inwardly facing sides 30,31 of the first and second housing part 26,27, respectively, in a first position of the housing. The first position of the housing is shown in Figs. 1-3, Figs. 3a-3e and Fig. 4.
A first gripping and releasing device 32 for gripping and releasing the first elongated element 12 of the retaining device 2 is arranged in the first housing part 26 and a second gripping and releasing device 33 for gripping and releasing the second elongated element 12 of the retaining device 2 is arranged in the second housing part 27.
Each of the first and second gripping and releasing devices 32,33 comprise a first and a second mutually spaced pressure rods 34.35 and a gripping member 36. The first and a second pressure rod 34,35 are mutually spaced corresponding essentially to the spacing between the outer end portions 15,16 of the elongated elements 12, and each pressure rod is relative to the inwardly facing side 30,31 of the respective housing part 26,27 movable between a retracted position and an extending position. In the extended position, the pressure rod engages, in the first position of the housing, an outer end portion 15,16 of an elongated element 12 of a pelt-retaining device 2 arranged on a pelt board 3 fastened in the pelt board-holding device.
The gripping member 36 is relative to the inwardly facing side of the respective housing part 26,27 moveable between a retracted position and an extending position and comprises a first and a second arm 38,39 comprising an outer end thereof cooperating gripping and engagement means 37a,37b being movable away from and towards each other and configured to engage and grip, in the first position of the housing, the handle part 20 protruding from the outer surface 14 of each of the longitudinal elements 12, see Fig. 8.
Further, the apparatus can comprise additional pressure rods illustrated by the arrows 40,41 and being moveable between a retracted position an extended position. In the extended position, a pressure is applied to the outer free end of the ratchet bar 17 in a direction towards the pelt board, such as towards the longitudinal board axis LA.
As it appears from Figs. 1 and 4, the housing 25 is arranged on a housing support 42 and moveable in a transverse direction along tracks 43 of the housing support 42 between the first housing position, shown in Figs. 1-3, Figs. 3a-3e and Fig. 4, where the retaining device 2 on the pelt board is arranged between the inwardly facing sides of the first and second housing parts 26,27 and a second position where the housing 25 is moved transversely away from the pelt board 3 and the pelt board is not accommodated in the spacing 29 between the first and second housing parts.
As it appears from Figs. 1 and 4-6a, the housing support 42, and thereby the housing 25, is additionally moveable along an upright column 44 having a column axis being essentially parallel to the longitudinal pelt board axis LA, when a pelt board 3 is fastened in the pelt board-holding device. Thereby, the housing 25 supported by the housing support can be moved to any vertical position and especially to the first position where the gripping and releasing devices are in the position for gripping and releasing the elongated elements of the retaining device and remove the latter from the pelt. Additionally, the housing support 42 is movable between a position where the housing 25 is in its second position and a position where the housing is in an elevated third position. From the position of the housing support 42 where the housing in its third position, the housing support and thereby the housing 25 is laterally movable to a position where the housing is in a fourth position above an upper opening 45 of a retaining device store 46 configured for receiving the elongated elements 12 of the retaining device 2. The retaining device store 46 is preferably movable relative to the housing supported by the housing support in order to arrange each opening of a retaining device store 46 having a number of openings in the correct position for receiving the elongated elements 12 of the retaining device when they are released.
The retaining device store 46 has a number of upwardly open storing rooms divided into two storing compartments 47, 48 by means of a dividing wall 49. The storing compartments are configured and shaped to receive and stack the pairs of elongated elements 12 of the retaining device 2 corresponding to the pairs of elongated elements forming the retaining device being removed from the retaining engagement with the pelt on the pelt board.
The compartments 47, 48 can be configured and shaped to receive and store the elongated elements 12 in the shape of the elongated elements before being elastically bent to bring the respective inner surfaces thereof in retaining engagement with the outer surface of the pelt and retain the pelt on the pelt board, see especially Fig 6a.
The pelt-retaining device 2 comprising two identical elongated elements can be removed by a method of the invention according to the following steps carried out by means of the above described embodiment of the apparatus of the invention:

a. fastening the lower end 6 of the pelt board 3 with the pelt retained thereon by the pelt-retaining device 2 in the pelt board-holding device, whereby the pelt board will be arranged in an upright position, and moving the housing 25 to the first housing position shown in Figs. 1 and 2 where the pressure rods 34,35 and the gripping members 36 of the gripping and releasing devices are in the retracted position,
b. bringing the gripping member 36 into engagement with the handle part 20 on the outer surface 14 of each of the elongated elements by moving the gripping member to the extended position as shown in Fig. 3 and moving the cooperating gripping and engagements means 37 a, 37 b towards each other, as illustrated in Fig. 3b,
c. applying a pressure to the outer surface of each of the outer portions of the elongated elements 12 provided with a ratchet bar 17 by moving the pressure rods 34 to the extended position, whereby the ratchet bars flex inwardly and away from the engagement with the pawl means 18 as illustrated in Fig. 3c. When all the pressure rods 34,35 have been retracted to their retracted position, the gripping members 36 are retracted to their retracted position and the elongated elements 12 of the retaining device 2 are thereby removed from the retaining engagement with the pelt on the pelt board as illustrated in Fig. 3e,
c1. prior to retracting the gripping members to their retracted positions, applying a pressure to each of the outer end portions of the elongated elements being provided with a pawl means by extending the pressure rods 35 to their extended position.

When a pressure is applied during step c1 to each of the outer end portions of the elongated members being provided with a pawl means, the pawl means flexes outwardly away from and out of a possible engagement between a tooth of the ratchet bar. Thereby, the risk of not obtaining a disengagement of the ratchet bar from the pawl means is eliminated. If not, it is possible to apply a pressure to the outer free end of the ratchet bar in a direction towards the pelt board, such as the longitudinal board axis by means of the pressure rods illustrated by means of the arrows 40 and 41 in Fig. 3d in order to disengage the ratchet bar from the pawl means.
When the pressure rods have been retracted to their retracted position, the gripping members 36 are retracted to their retracted position, thereby removing the elongated element of the retaining device 2 from the pelt board as mentioned above.
The pelt can then be removed from the pelt board.
Additionally, the elongated elements 12 of the pelt-retaining device 2 gripped by the gripping members 36 can be delivered to the retaining device store 46 by moving the housing 25 supported by the housing support to its second position and thereafter moving the housing on the housing support 42 to its elevated third position. The housing 25 on the housing support 42 is then moved to its fourth position above the upper opening 45 of the retaining device store 46 as shown in Fig.5 and 6.
In the fourth position of the housing 25, the gripping members 36 of the gripping and releasing devices 32, 33 can be extended to their extended positions to bring the elongated elements from their bent shape and state shown in Figs. 5 and 6 and into their straight shape and state shown in Fig. 6a. The housing 25 can then be moved downwardly to insert the elongated elements 12 in the respective storing compartments 47,48 of the retaining device store 46. The gripping members 36 of the gripping and releasing devices 32, 33 can now be retracted to their retracted positions leaving the elongated elements in the respective compartments 47,48. Finally the housing is moved back to its first position for removing the next pelt-retaining device from a pelt on a pelt board.
