Abstract

750,416. Drying hides and skins. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 8, 1954 [June 9, 1953], No. 15797/53. Class 34(2). [Also in Group VIII] Hides or skins are dried by confining the workpiece between the surfaces of a plane rigid member and a flexible member, one of which is vapour transmissive when wet, and applying heat and vacuum to the workpiece so confined in such a manner as to cause the flexible member to press the workpiece against the rigid member. Preferably the workpiece is confined between the surfaces of a porous plate and a flexible impermeable sheet heat applied to the workpiece thus confined and the vacuum applied to the surface of the porous plate opposite that with which the workpiece is in contact. In the illustrated apparatus the leather to be dried, 23, is supported on a plate 20 made of porous material and covered by a flexible sheet 22 which extends over the leather and contacts the porous plate 20 beyond the periphery of the leather. The plate 20 is spaced from a supporting face plate 10 by a series of cross pieces 30 provided with interconnecting channels 32 and a vacuum is applied to the space below the plate 20 by a vent 36 connected to a pump. A duct 40 supplies hot air to the upper surface of the impermeable flexible sheet 22. Alternatively heating may be effected by infra-red lamps. Shrinkage of the workpiece during drying is prevented by the action of the flexible sheet which holds the workpiece firmly against the porous plate 20. The grain surface of the workpiece is in contact with the impermeable sheet 22. The porous plate 20 may be made of sintered ceramic or metal or of a heavy wire mesh or other rigid perforated surface covered with felt, its essential characteristic being that it is vapour transmissive when wet.
