Abstract

Improvements in apparatus for vacuum drying flat objects, particularly large leather and leather, of the type that includes a plate that serves as a support for at least one object to be dried, a heating means located on the side lower part of the support plate, a movable cover to cover the upper side of the support plate, this cover being made up of a flexible watertight membrane, provided on its inner face with a mattress of porous material and provided in its outline with a gasket sealing designed to cooperate with a peripheral part of the support plate, said cover serving to enclose the object to be dried deposited on the support plate in a hermetic space, and means that allow connecting said hermetic space to a vacuum source, characterized in that the support plate (11) is placed in the shape of a saddle on the back of an ass with a rounded corner (11th) and two lateral frogs (11b, 11c) practically flat and because the cover (b) has a corresponding shape.
