Green PLC 4 Roll Soft PVC Calender Machine For Leatheroid
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.

Soft PVC Leatheroid are divided into many kinds: .Cloth leatheroid,
Rain cape Leatheroid, Luggage leather,Sofa leather,etc.
Leather fabric is close to the cortex without adding plasticizers
to achieve a soft nature, it will not harden, become brittle, but
also has rich colors, patterns and other many advantages, the price
4M wide Calender Line is becoming the world largest Calender
equipment. The final product of PVC film is able to reach over 3.6M
(according to skills and technique of operation). At present, it's
mainly applied for flexible film and advertising film, such as
billboard, and digital printing, flooring etc.
Besides flexible film, it also can be applicated in construction
material, tarpaulin, awning, tent, ballute, life raft and life ring
Clothes decoration,rain cape,Luggage,Sofa,etc.
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.
