The 4 rolls are separately driven by 4 DC motors, which allows a wide rang of speed adjustment. The rotating speed ratio of the 4 rolls can be freely adjusted. The rolls are equipped with per-loading device and lubrication failure alarm device, as well as nip display and speed display.
The rolls are arranged in S form, which provides a strong state of being pressed and a convenience of being operated. The rolls are made of chilled cast iron of vanadium and titanium alloy with hard and anti-wear surface. The central-bored and well-processed roll makes temperature of the roll surface well proportioned.
The working face of the rolls 1# & 4# has a camber, which can eliminate bending impact on rolls in working process. Thus, it is possible to obtain products with same thickness along axial direction.
The transmission system adopts hardened-gear speed reducer, which has a compacted structure with lower noise and higher transmission efficiency.
The machine is equipped with emergency device. When an emergent accident occurs, the calendar will be immediately stopped to open the roll space so as to protect the operator and equipment.
The machine is chiefly applied to put rubber at the same time on both sides of fabrics (cord fabric, canvas, etc.); to rubberize fabrics; or to make rubber sheets.
