Application for example to the dehairing of cow hides.

Impregnating machine suitable for the leather industry

Multiple treatment machine for leather trade - for fleshing and cleaning and other operations by changing rollers

Multiple treatment machine is for treating skins and leather and changes in the type of operation are made by changing the tool whilst the driving system for the skins remains the same. In a machine in which, after fleshing the hides, the impurities are removed from the wool by a washing process, the operator spreads the skins over a carrier roller with the wool side downwards. This roller can oscillate between a charging position and a running position by press. on a pedal. In the latter position, the skin is between the carrier roller and a driving roller, which rotates in the anticlockwise direction; at the same time the skin is applied against a fleshing roller (I) and any pieces of flesh are removed. The skin passes between rollers to a second carrier roller which is applied against a second fleshing roller (II) which completes the process. The skin is tasken to a cleaning roller (III) where washing is effected between this and a carrier and driving roller; the skin having been turned over so that the wool side is offered to the cleaning roller. The skin is then evacuated from the machine. Other operations can be effected on the same machine by replacing rollers (I), (II) and (III) by other appropriate rollers.

Plant and process for the continuous treatment of pelts or leathers in a liquid

Plant and process for the continuous treatment of skins or leathers in a liquid, in which a stream of liquid is created, maintained and controlled in the tank (1), which is capable of entirely driving the skins or leathers in lengthwise motion in the tank (1) from the entry end (2) as far as the exit end (3). Application to the soaking of skins of animal origin.

AUTOMATIC MACHINE FOR THE SKINNING OF THE LEATHER.

FLEXIBLE MEMBRANE MOLDING DEVICE

- L'invention concerne un dispositif de mise à plat (13) de membrane souple (12), du genre pièce de peau animale, comprenant : - au moins deux éléments (2a, 2b) chacun conçu pour se déplacer en translation cyclique selon une trajectoire décrivant une courbe fermée, lesdits déplacements en translation cyclique desdits deux éléments (2a, 2b) étant au moins en partie symétriques pour que lesdits deux éléments (2a, 2b) viennent de façon simultanée et intermittente presser ladite membrane (12) contre un support (1) tout en s'éloignant l'un de l'autre pour étirer localement ladite membrane. - L'invention concerne un également un procédé de mise à plat de membrane souple associé. - The invention relates to a device (13) for flattening a flexible membrane (12), of the type of animal skin, comprising: - at least two elements (2a, 2b) each designed to move in cyclical translation along a trajectory describing a closed curve, said displacements in cyclical translation of said two elements (2a, 2b) being at least partly symmetrical so that said two elements (2a, 2b) come simultaneously and intermittently to press said membrane (12) against a support (1) while moving away from each other to locally stretch said membrane. The invention also relates to a method for flattening an associated flexible membrane.

Skin treating machines - cutting blades

Cutting rollers of hide-treating machines, such as those for removing wool, thinning, softening, raising the grain etc., require frequent grinding if they are to operate cleanly and rapidly; the cutting blades are quickly blunted and wear away more rapidly than desirable. In this arrangement the helicoidal blades of the cutting roller are given a definite inclination, instead of being radial, the blades are an extension of the chord of the circular section of the roller. The angle of inclination of the blades to the radii is 10-45 degrees; cutting is much improved and the hair, wool, or the superficial defects are truly cut and not sheared or torn away. The cutting edges are preserved for a longer period and the life of the blade is, therefore, much longer. In addition the machine works more smoothly and with a lower power consumption.

Treatment drum for leather

Drum includes a long section, in the form of a truncated cone, firmly connected to a base; a grid is provided for protecting the discharge valve against possible obstruction by the skins as well as for flattening the angle at the base of the drum. Blades, for entraining the skins are fixed in the wall of the drum and make an angle with the radial plane passing through the implanted edge of the blade. Thus the mechanical work effected on the skins is different according to the direction of rotation of the drum and so by turning the drum in the two directions two types of treatment can be effected in the same drum.

Rotating drum for treatment of skins - with internal endless screw for charging and automatic discharging at controlled rate (BR121076)

Rotating drum, mounted on a horizontal shaft, has a charging and discharging orifice opposite the driving end with its pulley and motor. An endless screw, coaxial with the drum, transports the skins and prods. from the opening into the drum, when the latter is rotating in one direction and discharges them when it turns in the opposite direction. The endless screw moves the skins in a progressive manner which can be controlled by altering the rotational speed of the drum. The shaft of the screw may be hollow so that liqs. can be introduced inside the drum. Introduction of the skins is facilitated when the drum turns in the working direction and the treated skins can be discharged, automatically and at a controlled rate, merely by reversing the direction of rotation.

Skin processing machine

Improvements to the cylinders of tannery machines

Removing dust from tanned skins such as chamois - permeable conveyor belts support skins held at full width

An installation for removing the dust caused by a grinding operation on tanned skins, esp. those with a light handle and very little body, such as chamois and kid, etc., has conveyor belts with holes or bands of woven or flat material with few open meshes but still permeable to air, pneumatic arrangements with nozzles for air blasting, and suction openings preceded by decompression chambers, covering both sides of the conveyor, with suction openings in which a set of rollers turn freely and support one face of the conveyor carrying the skin. Provides a suction device which cannot pull in and buckle the lightweight skins, thus doing away with manual straightening and brushing.
