摘要： A doctor arrangement for roll presses includes for each press roll (1, 2) a web transfer device (6, 7) which lies in abutment with the barrel surface of its respective roll or in abutment with a wire mounted on said barrel surface. The web transfer device (6, 7) comprises doctor sections (13) having doctor blades (8, 9) and included in a module system. The sections (13) are supported by a coarse shredded trough (5) arranged above the press roll nip (3) and forming, together with the doctor sections (13), a rigid construction in the longitudinal direction of the rolls (1, 2).

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.

摘要： The invention concerns a caring doctor blade for a paper/board machine, which blade comprises layers of fibreglass and carbon fibre and a caring layer as a rigid laminated structure, which caring layer comprises carbon fibres and grinding particles in direct vicinity of the carbon fibres. The orientation of the fibreglass layers is parallel to the longitudinal axis of the blade, and at least in some of the layers that contain carbon fibre the orientation of the carbon fibres is substantially diverging from the direction of the longitudinal axis of the blade. The invention also concerns a method for manufacture of a doctor blade for a paper/board machine by means of a pultrusion method.

摘要： The invention relates to an apparatus having a roll cover (12) for a calender roll (10) and a doctor blade (20) for doctoring the roll cover (12) on its useful surface, wherein the radially outer circumferential surface of the roll cover (12) forms its useful surface, that region of the roll cover (12) which adjoins the useful surface is formed from a material which comprises first hard-material grains (13) which are embedded into a filler matrix (14), and the roughness of the useful surface has a value within a predefined tolerance range. The doctor blade (20) of the apparatus has a fibre composite material which is configured for doctoring the useful surface of the roll cover (12) and in the binding agent (27) of which second hard-material grains (31, 32, 33) are embedded, the hardness, grain size distribution and surface morphology of which is selected to be coordinated with the tolerance range of the roughness of the useful surface of the roll cover (12).

摘要： For cleaning the surface of an embossing roll a nozzle (14) forms an air knife (16) which is directed against the surface of the embossing roll (12) while the embossing roll (12) rotates. A lubricant and solvent solution can be added to the air supply of the air nozzle (14) to prevent deposits from sticking to the surface of the embossing roll (12) and to dissolve any deposits that do stick to the surface of them embossing roll (12).

摘要： An apparatus (10) is disclosed for assisting in the release of a web (W) from contact with the heated surface (S). The apparatus (10) includes a material (12) which is urged into contact with the heated surface (S) upstream relative to the contact of the web (W) to the heated surface (S). The material (12) is devoid of metallic content and the arrangement is such that when the web (W) contacts the heated surface (S) downstream relative to the material (12), thermal energy is transferred from the surface (S) to the web (W). The web (W) is released from the heated surface (S) subsequent to the transfer of the heat, such release being facilitated by the material (12) being urged against the surface (S).
