Abstract:
A portable spray booth for applying paint to plank-like members. The portable spray booth includes a housing having a top wall, a bottom wall, a front wall, a back wall and a pair of lateral side walls. The front and back walls each has an opening therein. The openings in the front and back walls are aligned and are positioned generally between the top and bottom walls. A delivery pipe is positioned in the housing and extends around an interior of the housing. A plurality of nozzles is fluidly coupled to the delivery pipe. An inlet pipe is fluidly coupled to the delivery pipe and extends through one of the lateral side walls. A pump is fluidly coupled to a container for pumping paint out of the container. The pump is in communication with the delivery pipe.
Abstract:
Liquid atomization systems and methods including nozzle apparatuses having one or more liquid orifice and one or more fluid orifices associated with each liquid orifice for forming atomized liquid flows. In one application, one or more atomized liquid flows are formed adjacent a moving article and vacillated predominately non-parallel to the direction of the moving article, before depositing the vacillating atomized fluid flows onto the moving article.
Abstract:
An apparatus is provided for coating a concavity of a building board. The apparatus includes a conveyor for transferring the building board and one or more coating nozzles for paint jetting a coating to the concavity formed in a surface of the building board. Each of the one or more coating nozzles is a jetting nozzle including a center jetting orifice, which is for jetting paint as a regulated jet in the form of a paint membrane, and one or more air-jet orifices, which are for jetting air along one or both of right and left edges of said paint membrane. The coating nozzles are controlled based on information of a cross-sectional geometry in crosswise direction of the concavity.
Abstract:
The invention relates to a method for directly or indirectly applying a liquid or pasty application medium (2) onto one or both sides of a continuous surface (4), wherein the application medium (2) is applied to the surface (4) in a plurality of single application regions by means of a plurality of single application nozzles (12) spaced apart from one another side by side and/or in succession in the direction of width (B) and/or longitudinal direction of the surface (4) and clearly distanced (D) from the surface (4), the application medium (2) emerging from each of these nozzles, wherein adjacent single application regions each intersect (U) at least in part in their respective edge regions, causing a layer of application medium to be produced across substantially the entire width (B) of the surface (4) to be coated. The invention also relates to an apparatus for performing this method.
Abstract:
An apparatus applies a coating medium onto a coating area of a moving substrate. In the case of direct application, the coating medium is applied onto the outer surface of a material web such as paper or carton, or, in the case of indirect application, the coating medium is applied onto the outer surface of a transfer element such as a transfer roll, which transfers the coating medium onto the material web. The coating mechanism is provided with at least one opening for the discharge of coating medium onto the substrate. A panel element is positioned on at least one side of the two margins of the coating area a certain distance after the opening of the discharge element relative to the direction of discharge of the coating medium in order to prevent any deposits of the coating medium outside of the coating area, which thus defines the respective margins of the coating area.
Abstract:
A sprayer of an elongated shape receives a desired liquid from an outside urce and spray-applies the liquid onto a fiber in response to motivating force provided by pressurized gas. The unsprayed, virgin fiber enters the sprayer through an inlet hole, is sprayed on with the liquid as it travels the width of the sprayer and exits the sprayer as a sprayed fiber through an exit hole. The pressure of the motivating gas can be varied to provide the optimum jettisoning force for a selected liquid, taking into consideration the viscosity, volatility and other pertinent characteristics of the liquid.
Abstract:
A spread out foraminous tow of tensioned filamentary filter material is transported through a housing between an upper and a lower rotating cylindrical brush. The upper brush propels atomized liquid plasticizer against the upper side of the tow whereby a certain amount of plasticizer penetrates through the tow and is gathered in the housing within the range of bristles on the lower brush which propels the gathered plasticizer against the underside of the tow. The rate of feed of plasticizer to the upper brush is varied in response to changes in the speed of the tow, and the brushes are arrested when the transporting rolls for the tow are brought to a standstill. The lower portion of the housing constitutes a trough which surrounds the lower half of the lower brush and from which the gathered plasticizer is evacuated when the brushes are idle.
Abstract:
A method of applying liquid in a finely divided form onto a moving surface and an apparatus for carrying out that method. A flow of air containing suspended liquid particles is passed substantially parallel to the moving surface and across its direction of movement within a container which extends across the width of the moving surface. The container has a slit or a series of openings facing the moving surface, through which slit or openings at least a part of the liquid particles entrained in the air flow are deflected and passed substantially normal to the surface to be deposited thereon.
Abstract:
A spraying apparatus for coating a hot and horizontally travelling glass sheet with a metal oxide coating film such as a heat-reflecting film by spraying an organometallic compound solution downwardly against the glass sheet. The apparatus comprises a spray gun movable over and transversely of the glass sheet, an outer enclosure and an inner hood, which has a middle portion defining therein a spraying zone and two end portions which are adjacent and upstream and downstream of the middle portion, respectively, and so shaped as to provide exhaust passages. The middle portion comprises two vertical guide plates arranged such that an ambient gas admitted through the space between the outer enclosure and the inner hood and an upper opening of the hood flows vertically downward into the spraying zone without unfavorably influencing the downward flow of the sprayed solution. The inlet to the exhaust passage in each end portion of the hood is so arranged as to smoothly exhaust the decomposition gas, residual portion of the sprayed solution and the admitted ambient gas from the spraying zone. In this apparatus, the metal oxide coating film can be formed with improved uniformity of its thickness and enhanced strength of adhesion to the glass sheet.
