4 Roll Rubber Calender/Four Roll Calendar Machine For Rubber Coating Or Rubber Sheet Calendering
Rubber calender machine is mainly used for Textile (cloth, canvas, etc.) of glue and eraser; steel cord adhesive; rubber compression and pressure type; cord attached to the fit of the isolation film and multilayer film.
According to the number of the rolls, it can be divided into 2-roll, 3-roll, 4-roll, 5-roll calendar, etc.
According to the arrangement of the rolls, it can be divided into "I" type,"L" type, "T" type, "F" type, "Z "type and" S "type, etc.
The four roll calender is mainly used for single-face and double –face one time continuous coating of fabric, canvas and other woven material, sheeting rubber stock , calendaring thin rubber sheet of inner liner and airtight layer of the radial tire.Structures features1.Roll is made of chilled cast iron alloy , through finish machining, with smooth and wearable surface, arranged in S shape , drilled on roll circumference, having good heating and cooling effects.2.For increasing calendaring accuracy, set preloading device, axis cross device and bending resistance device, etc. On rolls in order to eliminate bending caused during working.3.Single motor drives each calendaring roll, friction ratio of which can be regulated by pulling key so as to meeting different processes.4.Emergency stop is available for protecting operators and equipment.5.Electric control adopts imported PLC , guarantee control on the safe side, easy operation and high automation
Can be customized for you.

Our Advantage is?
| 1. The rolls Made of chilled cast iron of vanadium and titanium alloy. Roll face is hard and anti-wear. For heating up or cool down, the rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface. | 2. Transmission System Hardened tooth-surface reducer, Compact structure Higher transmission efficiency Lower noise Longer Service Life. |
 |  |
| 3.Electric-Control System Imported PLC Device Full-Automatic Control Easy to exchange the modes and reliable to operate the controller. | 4. Bearing&Sealing Bearing:Provide15years Service! Sealing:Provide10years Service! High-intensity Seal Ring Promise the oil will not leak Provide 10 years Service! |

5.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 different applications.
6.The rolls are equipped with lubrication failure alarm device, as well as nip display and speed display.
7.The rolls can be arranged in L, Γand I forms. The top roll has a camber that can eliminate bending impact on the roll in working process. Thus, it is possible to make products with same thickness along axial direction.
8.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.
