The present invention is directed to construction tools. The present invention includes tools used for applying mastic or mud to a work surface, for example, a flat box mastic applicator tool, blade assembly, and/or blade adjustment system, that have many improvements too numerous to mention all in the Abstract. The flat box mastic applicator may include unique walls. The blade assembly may have a non-uniform cross section, e.g., a blade holder with thinner areas and/or material removed at various locations along its lateral length. The blade holder may have a larger size outer end(s) to withstand bending or braking. The blade holder may have and arched shape, ribs or bumps for holding a blade more firmly, and a ridge or bump at its outer edge to act as a dam. The blade adjustment system may include symmetrical pins or posts and a tapered leaf spring. See further improvements herein.

An application method for applying an adhesive to an object includes applying, prior to applying the adhesive to a specified part of the object, the adhesive to a part different from the specified part, calculating an application quantity of the adhesive applied to the part different from the specified part, making a first correction configured to correct an application condition of the adhesive based on basis of a result of the calculation, and applying the adhesive to the specified part using the application condition corrected in the first correction.

An apparatus (1) for surface treatment of an elongate object (50), such as a wire rope, while the apparatus (1) travels along the object (50), including a squeegee unit (10) for applying a deformable material, such as a coating material, comprising: a first and a second opening (16, 17) which are mutually aligned and through which said elongated object (50) is able to pass in a longitudinal direction (12), wherein a squeegee element (102) is provided between the first and the second opening (16, 17) defining an opening (15) which is adapted to the cross sectional shape of the elongated object (50) to distribute a coating layer by wiping along the surface of the elongated object (50) passing through said opening (15).

The present invention provides a system for applying an anti-corrosion fluid to an anchor chain or cable. The system may include at least one set of nozzles disposed on the inner periphery of a conduit. Furthermore, at least one flap may be disposed on the inner periphery of a conduit, below the nozzles, for catching and smearing the fluid on the cable. Additionally, the invention may contain a reducer, attached to the bottom of the conduit, that may contain a flap, for catching the excess fluid and smearing the fluid on the cable.

According to one embodiment, a coating apparatus includes a coating bar configured to face a member to be coated, and a plurality of nozzles configured to supply a liquid toward the coating bar. A number of the nozzles is 3 or more. An arithmetic mean roughness Ra of at least a part of a surface of the coating bar is not less than 0.5 m and not more than 10 m.
