Dreiwalzengummi Calender

Three-roll Rubber Calenders The machine is chiefly applied to put rubber on cord fabric, canvas or other fabric; to rubberize fabrics; or to make rubber sheets. STRUCTURAL FEATURES 1. The machine is driven by DC motor with a wide range of speed adjustment. Working linear speeds can be steplessly regulated within the fixed range for various applications. The rolls are equipped with lubrication failure alarm device, as well as nip display and speed display. 2. The rolls are made of chilled cast iron with vanadium and titanium alloys. The roll face is hard and anti-wear. To heat up or cool down, the rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface. 3. The rolls are arranged in I, and forms. The top roll has a roll camber that can eliminate bending impact on rolls during working process. Thus, it is possible to make products with same thickness along axial direction. 4. The transmission system adopts a hard facing gear reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life.
