Combination of doctor blade, back-up blade and blade holder

Doctor blade assemblies are designed to optimize blade usage and reduce maintenance time in printing operations. This system replaces traditional wide doctor blades with a modular setup, consisting of a blade holder, a 10×0.102mm narrow doctor blade, and an 8×0.152mm wide back-up blade. The entire assembly is installed in the same position as a conventional wide doctor blade but offers a more efficient and cost-effective replacement process. Once installed, routine blade changes only require removing and replacing the 10mm-wide narrow doctor blade, eliminating the need to frequently replace the entire blade assembly. This design helps reduce downtime, lower material costs, and improve overall print consistency.

Advantages

Thinner doctor blades provide better flexibility, ensuring a closer and more even contact with the printing plate. This improves ink metering and helps prevent issues like haze and blade streaks.
No break-in period is required, ensuring consistent printing results from the moment the blade is installed.
Blade replacement takes only 10 seconds, reducing machine downtime and improving production efficiency.
Lower blade consumption results in significant cost savings, as only the narrow doctor blade needs to be replaced, while the back-up blade and holder remain in use for extended periods.
