摘要:
The invention is a system (1; 100; 200) for classifying hides (P; P', P") according to quality, comprising a frame (2) that supports a hide feeding line (3; 43) and a hide classification unit (25) comprising electronic processing and control means operatively connected to automatic measuring means (20, 21, 22) suited to measure the physical characteristics of the hides and arranged along the feeding line (3; 43), and to a manual unit (23) suited to assign a quality code chosen by the operator to each one of the hides. The feeding line (3; 43) comprises a plurality of distinct transport surfaces (4; 4', 4") suited to move the hides (P; P', P") forward according to an advance direction (F) towards a plurality of control stations (5; 5', 5"), each one of which comprises a hide control surface (6). The control stations (5; 5', 5") are connected in parallel to the feeding line (3; 43) through sorting stations (10; 40', 40") that are configured so as to selectively transfer the hides between the transport surfaces (4; 4', 4") and the control surface (6). The system comprises first power means (8) for moving the surfaces (4; 4', 4"; 6) forward and second power means (9) for the mutual movement of the surfaces (4; 4', 4"; 6), the power means being suited to allow the hides (P; P', P") to be selectively transferred between the transport surfaces (4; 4', 4") and the control surface (6) that belongs to a corresponding control station (5; 5', 5").

The machine for cutting leathers comprises: a bearing structure (1), an operating element (2), shaped in such a way as to exhibit a rotation axis (Z) and at least three distinct work planes (21, 22, 23), each of which is arranged about the rotation axis (Z) and is provided with an aspirating plate that is activatable/deactivatable such as to retain or release the leathers, and cutting means (3) associated to the bearing structure (1), at a relative side thereof, and movable with respect thereto. The operating element (2) is mountable on the bearing structure (1) rotatably about its rotation axis (Z) and is activatable in rotation about the axis (Z) in order to successively position each work plane (21, 22, 23) at three successive and distinct positions (P1, P2, P3) with respect to the bearing structure (1): a first position (P1) of placing the leathers in which the leathers can be positioned and stretched above the work plane (21, 22, 23) and held stretched thereon following activation of the relative aspirating plate; a second position (P2) of cutting the leathers, in which the work plane (21, 22, 23) with the leathers stretched and retained thereon by the relative aspirating plate is located below the cutting means (3); a third position (P3) of unloading the leathers, wherein the leathers can be unloaded from the work plane (21, 22, 23) by force of gravity following the deactivation of the aspirating plate.
摘要:
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.
摘要:
An improved machine (1) for the cleaning of flexible laminar surfaces including a support framework (2), which receives the flexible laminar surface and stands on a support structure (S), and cleaning means (3), facing the support framework (2), cooperating by contact with the laminar surface in order to remove impurities, dust and/or the like from the laminar surface itself. The improved machine (1) comprises regeneration means (4) operatively connected with the cleaning means (3) in order to clean the cleaning means (3) themselves from impurities, dust or the like previously removed by them from the flexible laminar surface.
摘要:
In connection with the various working operations in the production of furs, a not inconsiderable amount of manual labor is involved in the handling of the pelt boards or expansion pelt boards between the various work processes. To make the production of furs more profitable, manual labor is reduced to a minimum using a device for performing a complete or partial emptying/filling of a drying aggregate for upstanding expansion pelt boards, with or without tanned, or tanned and dried pelts, to one or more suitable receiving stations for further transport and/or handling. The device has a gripping element which can be activated for displacement, the movements of which are controlled by a control unit so that upstanding expansion pelt boards with or without tanned, dried pelts, are transferred automatically in upstanding position from the surface of the drying aggregate to a receiving point for further handling and transport.
