PLC controll 4 Roll Soft PVC Calender Machine Width 1500mm-2500mm.
Four Roll Calender is Mainly used in calender line for
manufacturing soft PVC products such as banner,.
clothes packing bag,wrapping film,plastic floor,PVC leatheroid,etc.
Calender Line FEATURES:
1. The 4 rolls are separately driven by 4 DC motors, which allow a
wide rang of speed adjustment.
2. 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.
3. The rolls are made of chilled cast iron of vanadium and titanium
alloy. The roll face is hard and anti-wear. For heating up or
cooling down, the rolls are either circumferentially drilled or
centrally bored so as to make temperature well proportioned on the
4. The transmission system adopts a hard-gear speed reducer, which
has a compacted structure with higher transmission efficiency,
lower noise and longer service life.
5. The machine is equipped with emergency device. When an emergent
accident occurs, the calender will be immediately stopped to open
the roll space so as to protect the operator and equipment.
6. PLC program controller is used in the electric system.

1. The mould adotps closed inner heating, which is environment
protection, energy saving.
2. The screws are made of nitrided steel and the surface coated
with alloy,which improves placticize capacity.
3. The unit has online recycling device to recycle waste material,
without heating and cooling, thus increasing output and saving
4. The swing device can adjust left and right range to make it in
the proper position and improve flattness of cling film.
5. Double rewinding position,each of which is separately controlled
by tension motor,roller changing without stop.
