Rubber Calender Machines are used for producing rubber sheets. These are also used to generate rubber based design on fabric. These high performance equipments consist of multiple rolls (developed from titanium alloy and vanadium based cast iron) that have up to 27 rpm operating speed. These rolls are centrally bored or are drilled circumferentially. Operation of these machines is conducted under specific temperature. Lubrication failure system of their rolls ensure about their trouble free functioning. Calender of these machines cease its operation mechanically during emergency situation to safeguard machines and operators. Speed of their DC motor can be adjusted easily. Quality of these Rubber Calender Machines has been verified on the basis of their service life, output, mechanism, speed of operation and operating cost etc.
