Our experience in constructing tanning machinery has brought to the realization of the RAL/LR machine, suitable for sheepskins processing, which presents constructive characteristics of extreme sturdiness, simplicity in the construction, in maintenance, adjustments and reliability. Machines with heated roller are different in the frame and in the working rollers’ disposition, in comparison to traditional sammying and setting out machines. RAL/LR is endowed with speed in production and above all, supply’s a notable yield of the leather. Besides, the RAL/LR is equipped with a security system which perfectly meets requirements requested by the relative legislation. Due to particular arrangement of the cylinder leather supporter the working area presents a notable anti-accident protection efficiency, as can be seen on diagram overleaf. – The machine is equipped a double safety device with metallic barrier and photoelectric cells in order to be completely safe. – The position of the leather supporting cylinder permits of a rapid and easy positioning of the leather, as well as s rapid and “mild” movement of opening and closing of the machine. – The adjustment between the staking cylinder and the supporting cylinders is effected by a handwheel placed on the right side of the machine, in an easily accessible position, with decimal reading on the graduated scale plate. – The staking cylinder and the heated device are equipped with a hydraulic device which allows a gradual approach of them to leather after closing of machine and a speed removal and gradual approaching during the reversal stage. This device can be inserted, not inserted or registered according to needs. This device avoids marks on leather which could be caused by the two cylinders during the above mentioned stages. -The stretching cylinder is assembled on two independent connecting rods and its adjustment is made by a graduated handwheel on both sides in order to keep its parallelism. – The drying pressure is adjustable by springs, or by hydraulic pistons. – The leather is extracted through the turn of rubber supporting cylinder and felt cylinder which are controlled by two independent hydraulic engines which receive oil in parallel. This produces a same rim speed which consents to save power, rubber and felt wear. Leather extraction speed, that can change from 10 to 35 m/min, is adjustable with hydraulic power placed on the left side of the machine. Electrical equipment is completely contained in a stainless steel waterproof box placed on the right side of the box. -In the combined setting machine with heated cylinder type RAL/LR, the conveyor cylinder is made of chromium-plated steel which is polished and heated through electric resistances. Temperature is adjusted by a thermostat equipped with graduated pointer placed on controls board together with a watch through which you can set up starting time of cylinder heating so that you can find the machine ready for working when you want. Carter are stainless steel. On request, machine can be equipped with automatic device for opening and reversal.
