Chamber doctor blade systems

Thanks to the asymmetric chamber design, the angles at the doctoring blade and the sealing blade towards the anilox roller are optimized. This allows for a high precision and consistent ink wipe at the working blade, eliminating issues like ink spitting or ghosting.

At the same time, the enhanced flexibility at sealing blade lets ink from unemptied cells pass through back into the chamber, avoiding dripping at the sealing blade ("back doctoring") that tends to occur in symmetric chamber systems.

The “kiss impression” technology of our chambers is based on low-pressure doctoring. This means the chamber is running at minimum pressure against the screen roller. As a result, doctor blades and end seals wear much slower, reducing costly machine down time due to blade and seal changes considerably.

Thanks to the mechanically locked chamber positioning system, the chamber cannot be engaged with too much pressure against the anilox roller (overpressure is a common cause for scoring lines on the roller), which is beneficial for the anilox roller service life.

The patented blade clamping system makes it possible to change doctor blades in seconds, no need for tools or compressed air. The blade is securely clamped with a special rubber profile along the chamber.

Most AkeBoose chamber systems also feature a service position, so that doctor blades and end seals can be changed directly on-press, without the need for taking the chamber to a maintenance or service area.

The clean interior design of the chambers and easily accessible blade clamping system are very easy to keep clean. There are no corners or grooves where ink could deposit.

Consequently, printers can concentrate on printing rather than spending their time cleaning.
