Diamond Dot Paper (DDP) Coating Machine

The TT-LG (1000~1600) diamond dot paper coating machine is a dedicated coating equipment designed for the production of diamond dot paper (film). Through sequential coating on both sides (A and B) using diamond-pattern gravure rollers, it forms a regular diamond-shaped adhesive dot pattern on the paper surface. The products are widely used in high-voltage insulation applications such as transformers, power equipment, and electronics. The machine is suitable for producing diamond dot paper (film) with a width range of 960–1600 mm. The complete system consists of unwinding, A-side dot coating head, B-side dot coating head, oven, cooling section, pull-roll, rewinding, and electrical control units.

·Ergonomic Design
Unique and rational layout eliminates the need for elevated installation, making operation safer and more convenient while reducing building height requirements. A mobile unwinding stand facilitates easy paper loading and roll changes.
·Fully Equipped Functions
Cooling, moisture conditioning, static elimination, and adhesive circulation systems are all integrated, saving users the trouble of sourcing and installing these separately.
·High Automation
Centralized HMI at the main control console for automatic control of tension, speed, temperature, length, and other parameters. Multi-zone closed-loop constant tension control enhances stability and reduces waste.
·High Efficiency
High-efficiency oven with multi-zone automatic temperature control. Heating options include electric, thermal oil, and steam.
·Wide Application Range
Suitable for producing diamond dot paper (film) with widths from 960 to 1600 mm.
·Safety Design
Steel wire guards are installed above the heating elements inside the oven to prevent the substrate from directly contacting the heating tubes. The exhaust fan is interlocked with the main drive – the machine cannot start unless the fan is running.
