SJ-FMS-800 Dual-Extruder Extrusion Coating and Lamination Machine
SJ-FMS-800 Dual-Extruder Extrusion Coating and Lamination Machine is designed and developed by ourselves, as the first one nationwide.
It uses PP or PE as raw material, coat and laminate for double-sided tubular woven sacks, producing double-sided coated tubular sacks or double-sided BOPP color-film laminated woven sacks.
The machine is characterized by simple structure and easy to operate. Compared with a single-extruder and single-die lamination machine, our machine can accomplish double-sided lamination with the substrate in one production flow, which improves production efficiency greatly, reduces energy consumption and labors, and guarantees products' quality.
For double-sided color printed film lamination, there are two modes for your choice as follows:
Manual Registration Mode: using magnetic powder brake tension control, manually adjusting for color-film registration. It is characterized by simple structure, easy to operate, and convenient for adjustment.
Automatic Registration Mode: using color-mark photocell detection, automatically registering the detected signals and adjusting (to control the motors of nip rolls for film feeding), so as to achieve automatic registration for color films at both sides. It is characterized by accurate registration, good stability, and high automation, which is especially suitable for producing high-grade double-sided color-film laminated sacks.

The machine uses PP or PE as raw material, through the flow-casting coating and lamination technology, achieving single-sided / double-sided coating or paper-plastic lamination with substrates (plastic woven fabric), to produce coated or laminated products. The machine is equipped with advanced electrical and mechanical devices throughout the whole production flow from substrate unwinding, lamination to winding, to achieve single control and group control. The dual-station unwinder uses EPC for automatic guiding control of substrates, and brakes for surface tension control of substrates, achieving pneumatic splicing and non-stop roll changing. The laminator is equipped with a preheating roll for preheating and drying of substrates. Laminating roll, silicon rubber roll and press roll are of dual-interlayer forced water cooling structure, with good cooling effect. The dual-station winder adopts constant-tension surface friction winding, pneumatic transverse cutting, roll changing without shutdown, and equipped with an adjustable edge-trimming device, an edge-strip blowing device, and a length counting device.
Features:
1. The extruder adopts a two-layer construction, with long useful life and good stability. The computer-simulation designed runner is characterized by large extrusion capacity, good plasticization effect, and low energy consumption. The die is convenient for adjustment, with uniform film flowing. The width at both sides of the die is manually adjusted.
2. The laminator adopts a new three-roll construction, which is characterized by uniform pressing, easy to operate, safety and reliability.
3. The winder adopts swing-roll automatic tension control and press-arm horizontally pushing, to achieve straight winding and smooth surface. (An automatic roll unloading device is optional.)
4. Equipped with a turn bar system, to accomplish double-sided coating for tubular fabrics in one process.
5. About coating and lamination with substrates for jumbo sacks, a leveling and braking device shall be equipped, to guarantee the fabric surface shall be level before coating, so as to improve the products’ quality.
6. The machine can be equipped with HMI and PLC, to achieve automation functions such as program linkage adjustment, failure interlock, etc.
7. The lamination speed can be up to 200m/min, as per the customers' requirements.
