ABSTRACT:
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.
