SPLITTING MACHINE 
The machine permits to produce samples with customer defined thickness starting from finished products. The part to be cut is inserted between the motor-driven feed steel rollers and a blade, which position can be regulated with 0,01 mm accuracy, splits the part horizontally.
The high quality mechanical construction of the machine, the sharpening device with micrometric drive, the adjustable feed speed and the integrated lubrication system of the blade ensure excellent results while splitting rubber or thermoplastic products with hardness between 30 and 75 Shore A.
