Embodiment Construction

[0043] Detailed description of the preferred embodiment

[0044] With reference to the above figures, the drying plant of the invention, generally designated by reference numeral 1, is designed as part of a plant, generally designated R, for finishing dry hard hides P.

[0045] As known in the prior art, the finishing plant R comprises a first finishing unit R1 for depositing a first layer or film S' of a liquid finishing product on the surface of the hide P on the grain side.

[0046] That is, the first finishing unit R1 has an inlet portion I for the hide P to be treated and an outlet portion O for the treated hide.

[0047] A not shown moving conveying surface is inserted between the inlet I and the outlet O for the automatic and continuous feeding of hides P in a predetermined direction V.

Abstract

A method of drying hides and hides (P) during a finishing process. The finishing process comprises at least a first step a) of depositing a first layer (S') of a liquid coating or finishing mixture onto the hide (P), possibly followed by a second layer (S") of a fixative A second step c) on the first layer (S'). Drying comprises a first step b) of irradiating the first finish layer (S') with an alternating electromagnetic field with a frequency in the RF range, for The substantially complete drying of the first layer (S') is followed by a second step d) of irradiating the second layer (S") of fixative deposited in said second deposition step c). The device for drying hides (P) during the finishing process, designed to be located in a leather finishing plant (R), comprises a shielded duct (2) in which there is a moving conveyor for feeding hides in a predetermined direction (V) A surface (5) and an electromagnetic wave irradiator (8) for irradiating waves in the RF range are oriented towards the surface of the hide (P) coated with the layer (S', S").

Description

technical field [0001] The present invention has general application in the field of tanned and nonwoven (artificial leather) fabrics, and in particular relates to a process for forming crust leather by drying during the finishing process. [0002] In another aspect, the invention relates to a device for drying hides (hard) using the method. Background technique [0003] After various tanning, retanning and dyeing treatments, hides and skins are generally known to exhibit surface imperfections that develop naturally in the life of the animal (scratches due to puncture wounds, contact with barbed wire or thorns), or caused by Surface defects caused by poor leather preservation after peeling. [0004] In these cases, the dried hide (hard pelt) is subjected to a procedure commonly known as finishing, in which the imperfections are removed or made less visible for better use of the hide. [0005] Finishing can be a mechanical process or a chemical process. In one of the chemi...
