Daetwyler Corporation has developed a chamber sealing doctor blade for flexographic printing that incorporates a foam tape applied to the doctor blade to provide a positive seal.
The company offers foam seals on its entire line of flexographic doctor blades.

“In addition to the variations now available in steel, blade thickness and tip configurations (radius as well as multiple options of bevel and lamella), Daetwyler is also making this foam tape available on its complete line of specialty coated doctor blades,” says Johnny Stamey, doctor blade technical product manager. “These special coatings are engineered to reduce friction at the contact point, extend wear and blade life, limit streaks and anilox score lines, protect against very abrasive inks (TiO2 whites), and provide the cleanest, sharpest wipe for the highest line screens available used in flexographic HD printing.”

Since it’s initial launch of the standard lamella doctor blade in 1972, Daetwyler has developed a variety of specialty coated and uncoated doctor blades for the industry.
