Components & Systems

In flexographic printing and coating technology, the chamber blade system is used to ensure a constant supply of ink, varnish, or other media to the printing form.
This system consists of a chamber blade connected to a closed circulation system. The printing ink, varnish, or coating material is automatically replenished at the required viscosity. The system transfers the low-viscosity medium to the anilox roller, which is equipped with tiny indentations. These indentations absorb the ink, varnish, or other materials. The doctor blade removes the excess medium from the surface of the anilox roller before it is transferred to the printing form.
A pump ensures that the ink chamber is continuously supplied with ink, varnish, or coating medium. These media are applied directly from the chamber to the anilox roller by means of a doctor blade. A doctor blade, which serves as a working blade, is set to remove excess medium from the anilox roller surface. A second doctor blade, the trailing blade or closing blade, seals the doctor blade comb.
