Abstract:
A beam construction, particularly a so-called doctor beam, for use mainly in pulp and paper mills to carry blade holders (7) intended to hold doctor blades. The beam (1) is a composite-construction hollow beam, which also includes at least one composite construction pre-tensioning rod (9, 10, 12). The construction has an essentially triangular cross-section.
Abstract:
A support beam for a long functional unit, specifically in a paper and/or coating machine, including a long hollow body having a round or polygonal cross section and manufactured from a fiber reinforced material which was produced in a winding process, whereby the invention provides that the fiber reinforced material is one having a modulus of elasticity of >100 Gpa, and a heat expansion of ≦2×10−6 1/° K in its longitudinal direction, as well as a fiber orientation whereby a first fiber content of 70% to 90% is approximately parallel to the longitudinal direction and a remaining second fiber content is aligned in the circumferential direction.
Abstract:
The invention relates to a holder for a cradle of a coating bar or for a coating blade in a coating unit and a method for securing the cradle of the coating bar or the coating blade in a coating device. The coating bar or blade are arranged to spread and smooth a size film or a corresponding layer of coating agent onto a face of a moving base to be coated by loading the coating bar or blade against the moving base. The moving base may be a roll of a size press or the web passed over a back-up roll. The cradle of the coating bar or the coating blade is mounted in a holder arranged in an application beam transverse to the machine direction. A journalling duct transverse to the machine direction is formed in the frame of the holder. An oblong member is arranged rotatably in the journalling duct and comprises a cam-like projection of eccentric section. The member can be rotated for the purpose of fixing the cradle of the coating bar or the coating blade in its place. In this position, the cam-like projection rests against a rear face of the cradle of the coating bar or of the coating blade and secures the cradle or coating blade against a support provided on the application beam.
Abstract:
A spreading device for the coating of moving material webs, especially paper or cardboard includes a clamping mechanism adapted to alternatively hold a doctor rod support bed or a coating blade, a pressing tube for pressing a doctor rod mounted on the doctor rod support bed onto a counter roll or a material web guided by a counter roll, and a profile strip having a tip portion adapted to press against a coating blade, the profile strip movable in a direction transverse to the counter roll by a displacement device. A plane defined by a pressing force through a contact region of the pressing tube and the doctor rod support bed and a plane defined by a pressing force through a contact region of the profile strip and the coating blade are disposed transversely with respect to a length of the counter roll and are either parallel or disposed at an acute angle to one another.
Abstract:
A fountain type web coating applicator and method wherein flow of coating material from source to a doctor blade coating nip with the continuously travelling web is subjected to a plurality of successive pressure drops so that coating material reaches the coating nip uniformly throughout the extent of the doctor blade edge. One of the pressure drops is through a multi-port pressure drop device and another pressure drop is through a slit orifice pressure drop device. A novel arrangement for easy replacement clamping of the doctor blade is provided. A doctor blade thruster is adjustable up and down along the blade relative to the upper coating nip edge of the blade.
