To prevent a height difference from being produced between a metal sheath and a paint layer formed on a vane surface of a vane body. A coating apparatus includes a jig adapted to support a guide vane equipped with a metal sheath for covering a leading edge portion; a nozzle adapted to spray paint onto a vane body; a robot adapted to move the nozzle; and a control unit adapted to control a spraying operation of the nozzle and robot. The jig includes a movable covering body adapted to separably cover the metal sheath and cover an exposed portion of adhesive between a lateral edge portion of the metal sheath and the vane surface of the vane body, and a covering body drive unit adapted to move the movable covering body between a state in which the movable covering body covers the metal sheath and a state in which the movable covering body is separated from the metal sheath while covering the metal sheath. The control unit performs control to make transition from a sheath cladding coating mode to a finish coating mode.

Disclosed herein is a nozzle for a silicon container, in which scrapers are horizontally and perpendicularly provided at the front end of the nozzle, thereby preventing silicon from unintentionally spreading during the application of silicon. The nozzle for a silicon container includes: a nozzle body configured to provide a discharge path for silicon discharged from a nozzle container; and a horizontal scraper disposed on the nozzle body, and configured to prevent silicon, discharged from the nozzle body, from unintentionally spreading; wherein the horizontal scraper is horizontally disposed along a longitudinal direction of the nozzle body, and is formed to protrude to left, right, and front sides of the nozzle body. The present invention has advantages in that the waste of silicon is prevented and also work efficiency is improved.

A shield unit, intended primarily for the protection of a carpet from the accidental application of paint applied to an adjacent baseboard, and suitable for disposable use, consists of two superposed plies of a film, comprised or consisting of a plastic material, which cooperatively define a plurality of adjacent pockets and have a common, structurally reinforced leading edge. The shield unit is long and narrow, and is constructed to facilitate entry of its leading edge into the effective gap that is normally present between the bottom of a baseboard and a carpet on the floor; the pockets serve to receive the blade of a tool, such as a putty knife, to which force may be applied to assist in pushing the leading edge of the shield into the effective gap. The shield unit may be provided as individual, relatively short sections, typically at least 30 inches long and four inches wide, or longer units may be used to cover an extended length of carpet with a single section. A multiplicity of shield units may be cut or otherwise separated from a continuous length strip, typically at least eight feet long, which may be provided in the form of a roll or a folded stack.

An injector head for delivering particulate material from a feeder source to a receiver is fitted with a plurality of splitter bars extending generally laterally from the sidewalls thereof into the space through which particulate material is fed as it flows into a receiver. Spray nozzles mounted to said sidewalls below said splitter bars spray coating material generally laterally relative to said sidewalls and generally laterally relative to the length of said splitter bars so as to coat particulate material as it passes over and to the sides and ends of said splitter bars.

In general, according to one embodiment, a film coating apparatus includes a discharge section configured to discharge a film formation material; a voltage application section configured to apply a voltage to the film formation material, and to set the film formation material at a high potential relative to a film formation object which is subjected to film formation; a mask disposed at a position overlapping a non-coating portion of the film formation object along a direction from the discharge section toward the non-coating portion; and a potential adjusting module configured to make a potential of the mask equal to a potential of the film formation object.

A coating system for coating objects, wherein a coating material can be dispensed by an application device with a dispensing arrangement. A supply system having at least first and second feed containers for coating material are connected via first and second supply lines and first and second material valves, respectively, to the dispensing arrangement. Also provided is a cleaning system having at least one first cleaning line and a second cleaning line, to which rinsing agent can be fed via a first rinsing agent feed line and a second rinsing agent feed line, respectively. The first and second cleaning lines are connected via first and second cleaning valves to the first and supply lines, respectively. The first cleaning line and the second cleaning line are connected via a connection line at connection points disposed in front of each cleaning valve relative to the flow direction towards the dispensing arrangement.

An injecting body of the injector is provided with two outlets. One outlet is connected to an auxiliary nozzle in a threaded manner, and the other outlet is connected to an injecting element body in a threaded manner. The water taking signal nozzle circularly takes signal water and air conveniently and reliably, so that a low-pressure vortex region is discontinuously formed at one side of the injecting element body; formation and disappearance of a pressure difference between a left cavity and a right cavity can be implemented in an automatic control manner, and wall attachment of water and rotation of the injector are implemented. The auxiliary nozzle is primarily used for supplementing near water distribution of the double-nozzle injector capable of spraying at a medium and low pressure, so as to improve spraying evenness.

A modular spray gun manifold having a plurality of spray gun modules arranged in a lateral array each separated by an adjacent support assembly. Each spray gun module has a central liquid passage communicating with a spray nozzle and a transversely oriented liquid inlet port communicating through an outer side of the spray gun module for connection with an independently controllable liquid supply. The spray gun modules further include a recirculation port communicating between the central passageway and a recirculation conduit in an adjacent support assembly. A control valve of each module is operable when in open spraying position for blocking communication of liquid from the central passageway to the circulation port and when in a valve closing position blocking the liquid flow to the spray nozzle while redirecting liquid from the liquid inlet to the recirculation port for recirculation through the manifold array.

A paint shield 10 for receipt on top of a doorway floor and between a first door jam and a second door jam. The paint shield includes a flat base sheet having one end with a first cutout center on one end and dimensioned to match a cross section of the bottom of the first door jam and engage the sides of the first door jam to prevent wet paint from spilling onto the floor next to the door jam. The paint shield also includes a sliding top sheet received on top of the flat base sheet. The top sheet has one end having as second cutout with a second cutout center on one end and dimensioned to match a cross second of the bottom of the second door jam.
