Coating method having particulate material introduced from within the gap region between applicators
Patent number: 5650193Abstract: There is disclosed a coating method involving a dispensing apparatus defining a particulate material exit opening including: (a) rotating a first applicator and an adjacent second applicator against a substrate, wherein the first applicator and the second applicator define a gap region therebetween; and (b) introducing particulate material into the gap region from the particulate material exit opening positioned at the gap region and moving a portion of the particulate material across the gap region to the substrate, wherein the rotation of the first applicator and the second applicator rubs the particulate material against the substrate.Type: GrantFiled: September 9, 1996Date of Patent: July 22, 1997Assignee: Xerox CorporationInventors: Eugene A. Swain, Henry T. Mastalski, Nicholas M. Lamendola -
Patent number: 5536312Abstract: A doctor device, notably for machines used to coat paper or cardboard, with a relatively bendable, flexible doctor element fitted in or on a separate holder. At least along its length in the holder, the device features a convex crowning of its working surface about its longitudinal axis.Type: GrantFiled: January 26, 1995Date of Patent: July 16, 1996Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Zygmunt Madrzak, Bernd Kaufmann

Patent number: 5318629Abstract: An apparatus is provided for spreading a material on an object. The apparatus includes a continuously moving conveyor for moving the object in a downstream direction, and a dispenser for applying the material to the object. The apparatus also includes a carriage located above the conveyor, and a spreader coupled to the carriage for engaging the material applied to the object by the dispenser to spread the material on the object. The apparatus further includes a mechanism for moving the carriage in the downstream direction over the continuously moving object as the spreader engages the material, and another mechanism for providing movement of the spreader relative to the carriage from an first position in which the spreader engages the material to a second position in which the spreader disengages the material.Type: GrantFiled: January 2, 1992Date of Patent: June 7, 1994Assignee: Raque Food Systems, Inc.Inventors: Glen F. Raque, Edward A. Robinson, Larry A. Allen, Vola B. Edwards

Patent number: 5143744Abstract: An apparatus for measuring the dynamic contact angle of a coating on a discrete web segment includes a rotatable coating wheel around which the web segment is mounted and a syringe which produces a coating bead having no edge bead. The interface between the coating and the web is viewed in a plane parallel to the axis and the surface of the coating wheel and the contact angle is measured.Type: GrantFiled: June 19, 1991Date of Patent: September 1, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: Jerry J. Barth, Garry R. Zvan

Patent number: 5010841Abstract: An apparatus and method for applying sealant to a countersunk fastener hole. The apparatus includes a sleeve, an adapter tube within the sleeve, a nozzle housing attached to the adapter tube, and a tip within the nozzle housing. A guide pin is attached to the adapter tube and follows an oblique slot in the sleeve. To operate, the sealant applicator is inserted into a countersunk fastener hole, engaging the tip with the countersink of the hole. The tip depresses into the nozzle housing, ejecting sealant onto the countersink. The adapter tube is pushed into the sleeve, moving the guide pin along the oblique slot in the sleeve. This guide pin movement rotates the adapter tube, nozzle housing and tip, causing the tip to uniformly spread the sealant around the countersink.Type: GrantFiled: May 23, 1989Date of Patent: April 30, 1991Assignee: McDonnell Douglas CorporationInventor: William R. Stewart

Patent number: 4777877Abstract: An apparatus and method for oscillating the ink form rollers and dampening form roller in a lithographic printing press to apply a smooth, relatively uniform coating of ink to the ink-receptive areas of a lithographic printing plate and to prevent ink from being transferred from the dampening form roller to the ink-rejecting areas of the printing plate. The ink form rollers and the dampening form roller are each comprised of a hollow cylindrical metal core surrounded by a rubber covering. First and second bronze bushings are partially inserted into the hollow core at respective opposite ends of the roller. Each roller is mounted on a shaft rotatable about its own axis. The shaft has first and second shaft keys for mating with complementary first and second keyways formed in the respective first and second bushings to allow the bushings to engage the shaft for common rotation while allowing the roller and bushings to slide axially with respect to the shaft.Type: GrantFiled: September 22, 1986Date of Patent: October 18, 1988Assignee: Airsystems Inc.Inventor: Milton R. Lemaster

Patent number: 4667879Abstract: A valved flow control dispenser including a slot nozzle through which molten thermoplastic material is dispensed onto a substrate. The slot nozzle includes a nozzle body within which there is a transverse cylindrical bore, which bore is intersected by two spaced radial openings. One of these openings is in fluid communication with a pressurized source of molten thermoplastic material, and the other opening is in fluid communication with a slotted discharge opening of the nozzle. A cylindrical flow control member having a groove provided in its exterior surface is rotatably mounted within the bore. This groove is of varying width and provides a flow path for molten thermoplastic material between the openings in the bore. By varying the rotatable orientation of the cylinder relative to the openings, the width of molten material dispensed from the slotted discharge openings of the nozzle may be varied.Type: GrantFiled: August 21, 1985Date of Patent: May 26, 1987Assignee: Nordson CorporationInventor: Peter E. Muller

Patent number: 4190684Abstract: Rubber is applied to a cylindrical workpiece by a feed surface arranged to form a nip with the workpiece into which the rubber is caused to be drawn by movement of the feed surface along the workpiece. The resulting compression of the rubber in the nip renders the rubber plastic so that the rubber flows onto the workpiece to form a layer of thickness determined by the spacing of the feed surface from the workpiece on the workpiece surface. The layer of rubber is then smoothed either by roller or smoothing plate and is then vulcanized.Type: GrantFiled: July 28, 1978Date of Patent: February 26, 1980Inventors: John H. Barwell, Aleksander Wielesiuk
