Abstract (en)
[origin: ES8205511A1] An apparatus and process for expanding the area and for drying of leather pieces, felts and other similar flat materials. On both sides of the leather elastic foils impervious to air are disposed, a vacuum is connected to the space between the two foils and then forces are applied for enlarging the area of the foils, where the forces are predominantly disposed in the plane of the foils. Thermal energy can be fed to the flat material. The forces can be intermittently applied and they can be provided preferably by hydraulic or pneumatic means.
