PU & PIR Sandwich Panel Production line

Up & down-lift are achieved by the use of a hydraulic cylinder which moves right and left supported by 4 wheels by 4 wheels on a rail. Two units are needed for Upper Coil and Lower Coil operation. The steel sheet(coil) is mounted on an uncoiler by the coil car at which point 4 wedges are expanded, and then 4 wedges are expanded, fixed by hydraulic power, and then driven by a motor. A rubber roller is mounted above the uncoiler for the purpose of preventing the coil (steel sheet) from suddenly uncoiling and over-uncoiling in motion.
