Patent number: 10029411Abstract: A glue delivery system and method for providing precise application of glue on a substrate. A bead of glue is extruded from a first glue chamber to a leading edge of the substrate. A trailing edge of the substrate is blown off and over to the nozzle to receive a smear of glue from a second glue chamber. A gear pump is controlled by a servo drive that is connected to a servomotor utilizing a gear reducer. The pump regulates the extrusion of the glue onto the substrate that is programmed with empirical data of gear reducer ratio at which the glue flows within a constant speed, torque, current, speed and position of the glue. The empirical data is provided to a programmable logic circuit to achieve a precise pressure related to volume of a glue deposition and speed of the substrate onto which the glue is applied.Type: GrantFiled: October 16, 2017Date of Patent: July 24, 2018Assignee: Elum Inc.Inventors: Svatoboj Otruba, Ranbir S.

Patent number: 6616760Abstract: The present invention is a film forming unit for discharging a coating solution from a coating solution discharge nozzle toward a substrate to form a layer on a surface of the substrate, which has a supply flow path for supplying a cleaning fluid to a discharge flow path continuing to a discharging port of the coating solution discharge nozzle. When the cleaning fluid is positively supplied directly to the discharge flow path of the coating solution discharge nozzle, the supply pressure of the cleaning fluid as well as the capability of cleaning is added. Therefore, further effective cleaning is attained in compare with the conventional case where a coating solution discharge nozzle is simply dipped into a cleaning fluid. In consequence, even when the discharging port of the nozzle is minute, it is possible to perfectly remove the contamination. This allows the discharge pressure to remain constant so as to form a uniform coating layer on the substrate.Type: GrantFiled: December 15, 2000Date of Patent: September 9, 2003Assignee: Tokyo Electron LimitedInventors: Takahiro Kitano, Masateru Morikawa, Yukihiko Esaki, Nobukazu Ishizaka, Norihisa Koga, Kazuhiro Takeshita, Hirofumi Ookuma, Masami Akimoto

Publication number: 20020157603Abstract: An apparatus and method for applying at least one solution of a predetermined viscosity to photosensitive material. The apparatus includes at least an application roller that applies the coating solution onto the photosensitive material. The application roller partially extends into a solution tray of the coating apparatus and is partially submerged in solution in the solution tray. In an arrangement of the present invention, a cascade wall and metering blade are positioned within the solution tray so as to define a first section at which solution enters the tray, and a second section which receives solution that spills over from the first section and includes a port which leads coating solution back to a coating solution tank for recycling or leads cleaning solution to drain. The apparatus further includes a washing arrangement that washes the coating apparatus in an efficient manner.Type: ApplicationFiled: May 3, 2002Publication date: October 31, 2002Inventors: Ralph L.

Patent number: 6471773Abstract: “Ghosting” and leakage problems in a doctor blade assembly are minimized or eliminated in a construction that includes a reservoir (10) partially surrounding a transfer roller (12) wherein a surface of the roller (12) is within the reservoir (10) for at least 180° of its rotation. The reservoir (10) is desirably split into two segments (50), (52) which are mounted for relative movement so as to allow access to the interior of the reservoir (10) as well as to the roll (12). Chambered end plates (82), (84) house seals (10) and receive parts (144) of the ends of doctor blades (40), (42) which extend past the end (142) of the roll (112) to promote good sealing at the ends of the assembly.Type: GrantFiled: June 15, 2000Date of Patent: October 29, 2002Inventor: Mark R.

Patent number: 6471774Abstract: The automated system includes a fluid dispenser having an applicator tip which is used to apply a fluid to an object. A compliance mechanism is utilized to assist in maintaining the applicator tip of the fluid dispenser in contact with the object during the coating operation. A robot can be utilized to advance the object past the applicator tip during the coating operation. The fluid dispenser is mounted on a movable arm to allow the fluid dispenser to be moved or rotated into and away from the position where fluid is applied to the object. The automated system provides a fluid application system that can apply a precise and repeatable layer of fluid to an object. The use of the robot allows larger objects to be easily handled and for the coating process to be done in a rapid fashion. The automated system is flexible and can readily accommodate changes in the object that is to be coated or the configuration of the coating that is to be applied to the object.Type: GrantFiled: May 5, 2000Date of Patent: October 29, 2002Assignee: DesigneticsInventor: Wallace F. Krueger

Publication number: 20020152956Abstract: An apparatus and method for applying at least one coating solution of a predetermined viscosity to a photosensitive material. The apparatus includes at least an application roller which is adapted to apply the coating solution onto the photosensitive material. A solution supply guide is positioned relative to the application roller to supply coating solution onto the application roller. The apparatus and method further includes a washing arrangement for washing the coating apparatus in an efficient manner. The washing arrangement includes a movable scrubber bar arrangement which retracts away from the application roller when the coating apparatus is in a coating mode of operation, and is movable to contact the application roller by way of brushes in a cleaning mode of operation. The apparatus and method further includes a recirculation system which alternatively supplies coating solution to the supply guide and cleaning solution to at least the washing arrangement.Type: ApplicationFiled: June 20, 2002Publication date: October 24, 2002Inventors: Ralph L. Piccinino, Kevin H. Blakely

Patent number: 6426119Abstract: The coater apparatus enclosure encloses the entire die of a coating apparatus includes an enclosure structure, a saturation station which saturates a supply gas with solvent, a device which supplies solvent-saturated gas to the enclosure to continuously purge the enclosure, and a device which controls the gas flow to the enclosure. The saturation station could include a heated jacketed vessel and a porous metal bubbler, or it could include a series of heat exchangers. No streaks can form due to coating fluid drying on the die lip because the gas supplied to the die enclosure is saturated with the solvent.Type: GrantFiled: September 8, 2000Date of Patent: July 30, 2002Assignee: 3M Innovative Properties CompanyInventors: Robert A.

Patent number: 6309463Abstract: A device for direct or indirect application of a liquid or viscous coating medium onto a moving material web, specifically a paper or cardboard web, includes an applicator unit which, in the direct application method, applies the coating medium in the form of a coating layer directly onto the material web at a point of application. In the indirect application method, the coating medium is first applied onto an applicator element, for example an applicator roll, which then transfers, at the point of application, the coating medium to the material web in the form of a coating layer. In addition, a drying device for drying of the coating layer is provided downstream from the point of application, viewed in the direction of flow of the material web. In the applicator unit, a device for moistening and/or warming the material web, coating medium or the coating layer is additionally provided before the drying device, viewed in the flow direction of the material web.Type: GrantFiled: May 2, 2000Date of Patent: October 30, 2001Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Harald Hess, Rüdiger Kurtz, Benjamin Mendéz-Gallon
