Beschreibung
Zusammenfassung:	The invention relates to a doctor blade device (10) for metering and/or leveling a liquid to pasty medium applied to a moving surface. When the medium is applied directly, the surface is a paper, cardboard or like fiber web. When the medium is applied indirectly, the surface is the surface of a transfer element which transfers the medium onto the fiber web. The doctor blade comprises a cylindrical doctor bar (13) and a contact tube (15) with which the doctor bar (13) is forced against the moving surface. The inventive device is characterized in that the doctor blade device (10, 20, 30) is a modular structure, comprising a top (11, 21, 31) and a base (12, 22, 32), whereby the top (11, 21, 31) is provided with a first holding device (14, 14a, 14b, 24, 34) for receiving the contact tube (15, 15a, 15b, 25, 35) and the base (12, 22, 32) with a second holding device (16, 16a, 16b, 26, 36) for receiving a clamped tube (17,17a, 17b, 27, 37).
