Described is a recycled leather product comprising, on a supporting layer, a thickness which has a mixture of ground leather fibres and powdered resins and/or heat-sensitive fibres. The invention also relates to a method for making the recycled leather product which comprises the following steps: – selecting and collecting waste from the processing of leather, substantially trimmings and swarf of finished leather coming from the steps for cutting leather goods and footwear, in such a way as to obtain a collected material; – crushing the material collected into pieces of controlled size, preferably with dimensions substantially equal to 10 mm, and mixing/homogenizing the pieces of controlled size, in such a way as to obtain granulated material; – grinding the granulated material for reducing it into leather fibrils, preferably having a size of between 0.5 and 1 mm, inclusive; – mixing the fibrils with powdered resins and/or heat-sensitive fibres and placing them in an orderly fashion on a supporting layer which has at least one adhesive surface portion, in such a way as to make a formed material; – consolidating the formed material by heat setting and compression; – cutting and rolling the consolidated material which is heat-set and compressed; – finishing the rolled material thus obtained to obtain a finished leather product.

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.

Described is a natural leather trimming machine including: an ironing device for stretching and removing creases and wrinkles from the leather, cutting means for cutting the leather along at least one cutting line, a detection unit configured to detect the position of the leather, the shape of at least one relative end edge, and the position of any defects close to at least one relative end edge, a plurality of conveyor belts and a first command and control unit configured to determine the cutting coordinates of the leather.
