This calender is mainly used for single-face one continuous coating rubber sheet of cord thread , fabric , other woven material . or calendering pure rubber sheet for OTR tire inner liner.
1.Roll is made of chilled cast iron alloy, cold-grinding surface , hard and wearable ;drilled on roll circumference, getting good heating and cooling effects.
2.Single motor drives each calendaring roll of three calender ,at two ends of which have friction gears, may regulate speed ratio by pulling key so as to meeting different processes.
3.For guaranteeing calendered product accuracy , provide axis cross device, pull-back device and pre-bending device for rolls.
4.Having emergency stop on machine for protecting operators and equipment.
5.AC or DC motor drive ,taking digital speed regulating device as driver, to guarantee the stability of output torque.
For one-side rubberizing fabric, canvas and other textile, and rubber sheet calendering for inner layer of tyre
Four row cylinder roller bearing of high precise is used to support the calender roll, which possess higher precise of rotation by contrast with self-aligning roller bearing.
Pre-loading and cross systems available by customer requirement , which keeps machine stable and the product with high precision thickness control .
Encoder of high precision is adopted for detecting motor speed of roll. Speed closed-loop control system keeps roll hard mechanical property while enlarging load.
