Abstract

The invention relates to a method for producing leather parts (18), which can be processed using saddler technology, from prefabricated final leather (12) for the automotive field. The final leather is split in a splitting process (13) with the formation of a contiguous and closed thin leather hide (14) with a proportional thickness in relation to the final leather of from 15 to 50% and a split leather hide (15) with a proportional thickness of from 50 to 85%. The thin leather hide (14) is then cut to size in a die-cutting process with the formation of predefined thin leather blanks and is lined over the full area of its rear side with a complementary lining blank made from a textile, fibrous and/or foam material which is lighter in mass than leather. In principle, the split leather hide can also be trimmed, cut to size and optionally split to a desired thickness and lined with the formation of split leather parts (19) which can be processed using saddler technology.
