By a new method for the fastening of pelts stretched on pelt-boards, the belt is secured in a stretched position on the pelt-board by means of a sleeve/bag which is drawn over and around the pelt, so that the pelt is pressed in and locked against the pelt-board by means of the sleeve/bag. The method gives rise to the need for the pelts to be stretched out longer on the pelt-board than has hitherto been possible without damaging the pelts, inasmuch as the pelts will have a tendency to shrink slightly more when they are not fastened to the pelt-board by means of the staples traditionally used. During the stretching of the pelt in a pelt processing machine, by imparting a vibrating movement to the pelt-board and/or the gripping elements while implementing the relative displacement in the longitudinal direction of the pelt-board respectively between the holding elements for the fastening of the pelt, and the first and/or second set of gripping elements for the stretching of the pelt, for example a mink pelt placed loosely beforehand on the pelt-board, it is achieved that the pelt can be stretch out to the desired length without damage to the pelt.
Method for the stretching of pelts (6) on pelt-boards (4) by a pelt-processing machine (2) which comprises means (10, 12, 14) for the execution of a relative displacement between a pelt-board (4) on which a pelt (6) is placed between holding elements, and gripping elements (16) for the securing of the pelt (6) during the stretching, characterised in that a vibrating movement is applied to the holding elements for the pelt-board (4) and/or the means (10, 12, 14) for the execution of the relative displacement between the gripping elements (16) and the pelt-board (4), and/or the gripping elements (16), during the execution of the relative displacement respectively between the pelt-board (4) and the gripping elements (16) in the longitudinal direction of the pelt-board, for the stretching of the pelt (6) which beforehand is applied loosely on the pelt-board.
A pelt-processing apparatus comprising at least a first set of holding elements for the fastening of a pelt-board (4) on which a pelt (6) is placed, and at least a first set of gripping elements (16) for fastening in the back side of the pelt, and/or a second set of gripping elements for the fastening of the leg side of the pelt, and means (10) for the execution of a relative displacement in the longitudinal direction of the pelt-board respectively between the holding elements for fastening of the pelt-board and the first and/or second set of gripping elements (16), for the stretching of a pelt which beforehand is placed loosely on the pelt-board, characterised in that the holding elements for the pelt-board (4) and/or the means (10, 12, 14) for the execution of said relative displacement between the pelt-board (4) with the pelt (6) and/or the gripping elements (16) for the pelt (6) on the pelt-board (4), are provided with a vibrator (20).
