Drums for dry milling to soften the leather by mechanical shaking to controlled moisture and temperature. In addition to the simple action of softening, some cleaning chemicals recipes may be used to obtain desired special fashion effects; for which the drums may be equipped by chemical dosing devices.
Softening and spreading of leather are the main aim of the staking process and also contribute effectively its yield. The head type vibration staking machines concept are based on pin design for wet or dry hides processing; the mechanical and electric device provide the synchronised oscillation motion.
The splitting process of the hide in horizontal layers allows to reach the desired thickness and simultaneously to recover a byproduct (split) which is processed in a same way like the hide from which it derives; this operation can be done at different steps of the manufacturing process. The splitting in finishing phase is practiced on finished hides using the machines that are equipped with a circular band knife mounted on wheels, specifically designed to facilitate the hide introduction. Equipped with micrometric precision systems, such as the insertion table inclination and blade position, that ensure the thickness adjustment with very hight accuracy. The blades are automatically rebladed through grinding stones mounted on cart system.
Cylinder machines, equipped with sandpaper or emery for the processing of leather with nubuck or suede effect, or to correct any defects on the leather grain side. Control devices with hydraulic drive are used to quickly reverse the direction of rotation of the feed roller and make it easier the manual extraction of the leather. The systems are supplemented by specific elements of dust extraction and collection in the bags.
Complete finishing lines with the drying, equipped with perlon threats or nylon cord transport conveyor, net conveyor or band conveyor. The dryers may be equipped with the heating system working by steam, hot water, diathermic oil, by gas, by catalytic gas heaters, the radiation which is produced by electricity, and others.
Padding and coating machines by roller finishing for color coat and top coat application, for effects and printing, impregnation, pigment coating waxing and fillers.
The embossing process is performed to impress on the skin surface a specific design. The pressing systems is essentially composed of two work plates, vertical movement of the lower is actuated by a hydraulic system. The plans themselves can be heated and maintained at the desired temperature by means of an electrical or heat transfer fluids.
