ABSTRACT:
For the production of articles comprising at least one layer of leather or simulated leather material and one layer of a synthetic resin connected to the first-mentioned layer in a shape-mating fashion, a mold cavity is filled with at least one layer of leather or a simulated leather material which later is in contact with at least one of the mold walls, and thereafter a synthetic resin, in the fluid condition or in a condition wherein it is rendered fluid, is introduced into the mold cavity. Finally, the synthetic resin is allowed to penetrate at least partially into the layer of leather or simulated leather material for the purpose of attaining an at least shape-mating bond therewith, and the peripheral edges of the layer of leather or simulated leather material are allowed to be covered by the synthetic resin.
