Abstract

A color chamber doctor blade has two doctor blade knives oriented in a roof-like fashion against a roller, from which the two doctor blade knives can be fixed on a doctor blade chamber body by means of a clamping plate. The clamping plate is in active connection with long-stretch fasteners in the axial direction (z) of the roller. The long-stretch fasteners are arranged substantially parallel to the clamping plate, and apply the force required for fixing at least one doctor blade knife. The resultant of the force exercised by the fasteners points toward the doctor blade chamber body.
