The present invention discloses a method for cutting raw or tripe leather with an optimized geometry, which increases the yield of the original raw or tripe leather (A) piece for all the production chain, concomitantly reducing the quantity of solid residues, since the cutting is carried out prior to the tanning stage. Said method is made possible by the use of a cutting table (C) which comprises a top (10) in trapezoid shape, with a plurality of metallic strips (20) juxtaposed in parallel, longitudinally at the lateral ends of the referred top (10). The claimed method has sustainable characteristics and reduces the environmental impact that is inherent to the leather industry, since it enables the use of the generated coproducts, of collagenic constitution, in the food or pharmaceutical industry, reducing the discard of residues in the environment.

A multi-layered material that includes a layer of natural leather or collagen leather with holes and/or micro-holes and coated with a hydrophobic agent, which is superimposed and adhered, by means of hydrolysis-resistant adhesives, said adhesives being arranged in a non-laminar fashion, to a layer of waterproof, breathable material to prevent the passage of water and to allow the passage of air therethrough.

The invention relates to a system made of an electronic display device having a display screen for displaying augmented reality, an electronic memory, and a cutting device for cutting planar cutting stock, e.g., paperboard, corrugated cardboard, film, textile, plastic, foam, or wooden slabs or sheets. The system has a computer unit for computing a position and alignment of the display device in relation to the cutting device. The display device is designed to be worn by a user and positioned in the field of vision of the user. The system is designed to display to the user retrieved cutting-stock-related information by means of the display screen in a manner readable by the user in the field of vision of the user, adapted to the position and alignment of the display device in relation to the cutting device, and linked to an actual and/or setpoint position of the cutting stock.

A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.

The present invention discloses a flexible leather slice blanking apparatus and an implementation method. The apparatus comprises a working table, a projector, an industrial camera, an installing support, a manipulator, a matrix chuck fixture and a base. The installing support is arranged on the working table and disposed in a corresponding range of a cutting region behind a numerical-control leather cutting machine. The projector and the industrial camera are respectively arranged on the installing support. The manipulator is installed on the base. The matrix chuck fixture is located above the manipulator and connected with the manipulator through a matrix chuck fixture installing frame. The blanking apparatus provided by the present invention is low in labor cost and high in efficiency; and moreover, leather slices can be classified and collected, thereby saving labor force and increasing production efficiency.
