Main Features:
1) Double Shaft-less paper roll stands suitable for 3-6 inch paper
core,automatic lift ,easier operation .
2) Auto splicer device realize paper in 150-300 m/min speed
exchange without decrease machine line speed
3) Ultrasonic type EPC system,makes frequent replacement materials
operation more simple
4) Hydraulic lamination structure design , can make coating thinner
and firm .
5) Trimming device make the finished coated paper rolls even
6) Special cutting knife and rewinder design makes high speed
rewinding shafts exchange possible.

PRE-TREATMENT
- The pre-treatment includes corona treatment and static elimination
on the surface of base materials. Especially in extrusion coating
process, corona treatment is needed to assist molten web to
permeate into the pores or cottony gaps on the surface of base
materials under the pressure of pressure roll, improving the
adhension between coating film and base materials.
- Corona treatment will stop when production line speed below 20m/min
and automatically starts when speed above 20m/min.
- The corona machine is equipped with work condition indicating lamp,
oil-immersed high-frequency transformer, electric digital meter
reading output power and adjustable low-speed interlock. It will be
warning on overheat,hyper-charger, breakdown and corona lost, and
works with high-efficiency and low-consumption.
Compound machine
- The coumpound device consist of cooling roller, silicone rubber
pressure roller, back-up roller, discharge roller, trimming
deflashing device, wheelwork pneumatic device and some other
devices. It is used to combine melted sheet film with basic
materials and is the key device of extrusion lamination or
extrusion coating. Its main functions are composite, cooling and
shaping.
- Its production line is equipped with external hard chromium plating
and steel rollers with double-deck clamp cover auger-type screw
channel. the clamp cover of screw channel is filled witth cooling
water to take away the heat of melted thin film so that composite
thin film can get a great result in cooling shaping, and this
greatly improves the fastness, smoothness and external beauty of
composite.
