1. 150m/min high speed has already reached the international most advanced level.
2. Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop， It will reduce the waste.
3. When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.
Characteristics of several coating methods -
These scrapers are made of high-precision cold-drawn round steel wrapped around stainless steel wire. If the wire scraper is rotated by the micro DC motor during the scraping, the effect is better. The wire scraper usually acts directly on the substrate when the glue is applied. However, it is generally only used for the pre-squeegee coating of the smooth roll. A precise squeegee of a comma blade is usually required later.
The air squeegee mechanism acts on the sizing roller by a uniformly sprayed gas (pressure) flow, which serves the purpose of squeegeeing. The gas (pressure) flow is required to be evenly distributed over the entire width of the optical roll, and this type of scraper is often used for scraping a good fluidity. The scraper has a high precision of scraping, and is currently widely used for coating scraping of whiteboard paper.
