The present invention relates to a scraping roller (1) for scraping the skin side of an animal pelt, said roller comprising a plurality of teeth (10, 20, 30, 40, 50, 60, 70, 80), each tooth comprising a scraping edge (11, 21, 31, 41, 51, 61, 71, 81) having a vertex (12, 22, 32, 42, 52, 62, 72, 82), wherein the axial position of the vertex (12) of the scraping edge (11) of a first tooth (10) has a minimum axial distance from one end (2) of the scraping roller and the axial position of the vertex (52) of the scraping edge (51) of a second tooth (50) has a maximum axial distance from said one end (2) of the scraping roller, and wherein at least one of said plurality of teeth (20, 30, 40) is situated intermediate between said first tooth (10) and said second tooth (50) and at least one of said plurality of teeth (60, 70, 80) is situated intermediate between said second tooth (50) and said first tooth (10), these intermediately situated teeth (20, 30, 40, 60, 70, 80) being formed so that the axial position of the vertex of the scraping edge of successive teeth varies gradually between said minimum distance and said maximum distance.

An apparatus (1) is disclosed for processing the skin side of a tubular fur (2), which apparatus (1) comprises:

a tapering mandrel (3) of rectangular cross-sectional shape on which the tubular fur (2) can be drawn so that the skin side of the fur (2) faces outwards,

a first scraper unit (4) and a second scraper unit (5) arranged on opposite sides of the mandrel (3) and each comprising a first scraper roller (4a, 5a) and a second scraper roller (4b, 5b) that are designed, during operation and in contact with the skin side, to rotate so that scraper elements (6) on the scraper rollers (4a, 5a) scrape the skin side of the fur (2), wherein said scraper rollers (4a, 5a) are arranged to rotate around an essentially vertical axis, to scrape the skin side arranged on side parts of the mandrel, and said first and second scraper rollers (4a, 4b, 5a, 5b) of said first and second scraper units (4, 5), during operation and in contact with the skin side, are arranged to act on the skin side with a friction force in the direction towards a thicker part (3b) of the mandrel (3), and

two additional scraper units (8, 9) both arranged to apply a force to the skin side from opposite sides of the mandrel (3) in a direction towards a thichker part (3b) of the mandrel and each comprising at least one scaper roller (8a, 9a) which are arranged to rotate around an essentially horizontal axis in order thus to scrape at least one part of the fur (2) that is not or will not be processed by the first scraper unit (4) or second scraper unit (5),

wherein said mandrel (3) is configured for being moved in its longitudinal direction.

The invention provides a fur processing apparatus, such as for processing mink fur, with a scraper unit with one or more rotating scraper roller (S) for removing fat and flesh from the leather side of the fur. A liquid spray unit is arranged to spray a liquid (L), e.g. water, onto one or more scraper rollers (S) so as to provide a liquid film (LF) on scraper blades of the scraper rollers (S). Hereby, it is possible to prevent fat and flesh from sticking to the scraper blades, thus destroying the scraping effect of the scraper rollers (S). E.g. water with a temperature of 40-60 °C may be used, and the water is preferably sprayed by means of a nozzle (N) towards one or two scraper blades immediately prior to entering into contact with the fur. In case of skinning machines which processed the fur with a sequence of more than one scraper unit, at least one of the scraper rollers (S) of the first scraper unit in the sequence is preferably sprayed with liquid (L).

A stretching apparatus for stretching a pelt on a pelt board, where the pelt has a substantially tubular shape which defines an inwardly oriented leather side, an outwardly oriented fur side, a nose end, a rear end and a back piece. The pelt board defines a top end for accommodating and fixating the nose end of the pelt, a circumferential wall for facing the inwardly oriented leather side of the pelt and a base end located opposite the top end. The stretching apparatus comprises a holding device for holding the base end of the pelt board, a fastening device for fastening the rear end of the pelt and being movable relative to the holding device for stretching the pelt. The stretching apparatus further comprises a fur side processing tool being supported movably relative to the pelt board along the first side from a nose end positioned to a rear end position and to be returned from the rear end position to the nose end position.
