DOCTOR BLADE
摘要:
A doctor blade, in particular for metering of inks and coatings from an engraved surface, has a flat oblong base body (1a) and a blade region (1c) with a working edge (5) being formed at one of the longitudinal sides of the base body (1a). The blade region (1c) is at least partially made of a plastics material (3, 4), whereas the working edge (5) is formed of the plastics material (3, 4). The base body (1a) is made from a reinforced plastics material (2, 3, 4). The opposing main outer surfaces of the base body (1a) are constituted by plastic layers (3, 4) made from a first material, where at least one inner layer (2) made from a second material having a higher rigidity than the first material is provided in between said plastic layers (3, 4). The doctor blade (1) therefore incorporates structural components of different rigidities, whereas a plastic working edge (5) is provided. This doctor blade (1) is at the same time rigid and non-abrasive. The wear debris is not harmful to the media and the doctor blade (1) provides sealing qualities. Due to the fact that the main outer surfaces of the doctor blade (1) are constituted by the plastics material the doctor blade (1) is not subject to rusting or oxidation and the safety for the user is enhanced.
