Patent number: 6277196Abstract: Apparatus for applying a coating of an insulation lacquer to a moving surface of a strip comprises a rotatable roller whose surface defines a multiplicity of cells and a reservoir containing a bath of heated organic/inorganic insulating lacquer in which a part of the roller surface is immersed when rotating. Insulating lacquer enters the cells of the roller surface and excess lacquer is wiped from the roller surface. A rotatable applicator roll having a substantially plain surface free of grooves or other indentations is rotated with its surface in contact with the surface of the lacquer carrying roller whereby lacquer present in the cells of the roller is transferred to the surface of the applicator roll. The surface to be coated is moved continuously past and in contact with the roll surface to apply a uniform coating of lacquer to that surface. The strip is preferably a strip of non-oriented electrical steel.Type: GrantFiled: July 21, 1999Date of Patent: August 21, 2001Assignee: European Electrical SteelsInventors: Gwilym Leslie Woodman, David Snell, Philip Beckley

Patent number: 6270577Abstract: An apparatus for applying a high solids coating to a surface of a base product is provided. The apparatus includes a rotatable coating roll that opposes a feeding roll. The rolls combine to define a nip portion through which a base product is passed. A cleaning blade is disposed in contact with the coating roll and a calendar box is disposed adjacent the surface of the coating roll.Type: GrantFiled: November 19, 1999Date of Patent: August 7, 2001Assignee: Fort James CorporationInventors: Kenneth John Shanton, Erland R. Sandstrom, Timothy Paul Hartjes, Dean Patrick Swoboda

Patent number: 6254678Abstract: A method and apparatus for applying pressure sensitive adhesive to a substrate, in which the adhesive is deposited on a transfer surface, such as a circulating transfer belt, dried, and subsequently transferred to a plurality of overlapping sheets. The sheets are preferably coated with a primer or a low adhesion backsize, or both, prior to application of the adhesive.Type: GrantFiled: June 7, 1995Date of Patent: July 3, 2001Assignee: Minnesota Mining & Manufacturing CompanyInventor: Johannes A. Ritter

Patent number: 6231670Abstract: A paper web impregnated with a liquid resin and following impregnation is coated with an abrasive particle containing coating mass or composition and then dried before a liquid resin is applied which does not contain the abrasive particles. The web is then finally dried and the resulting paper is particularly suitable as a cover sheet in the hot pressing of laminates since it minimizes wear of the laminate press.Type: GrantFiled: January 14, 2000Date of Patent: May 15, 2001Assignee: Vits Maschinenbau GmbHInventors: Siegfried Fischer, Willi Erkelenz, Ernst Klas, Gisbert Krossa, Udo Unger

Patent number: 6221158Abstract: A header tape for a curtain or the like comprises loop regions for use with a hook and loop fastener. The loop regions cause the header tape to be thicker in these regions. The loops of the loop regions will be pulled out under constant use unless the back of regions are coated by an adhesive. Using the difference in thickness between loop regions and the non-loop region, intermittent coating can be achieved by feeding the header tape through a small gap between a press roller and a coating roller. The gap is chosen so that it is smaller than the thickness of the loop regions but larger than the thickness of the non-loop region of the header tape.Type: GrantFiled: May 19, 1998Date of Patent: April 24, 2001Assignee: YKK CorporationInventor: Naoki Kondo

Patent number: 6214118Abstract: An external electrode forming apparatus is used to form external electrodes on the component chips. The external electrode forming apparatus comprises a component conveyer belt, a belt feeding mechanism, a component-inserting machine, a component-reversing machine, a paste-coating machine, and a component-discharging machine. For the component-inserting machine, the component-reversing machine, and the component-discharging machine, pressure pins are used to insert or move the component chips. These pressure pins have at the tip part a taper portion with a tip shape smaller than that of the component holding hole. Since the pressure pins of this type are used, the tip portions of these pressure pins may be prevented from impinging upon the opening edges of the component holding holes, and the pressure pins after the impingement may be hindered from forcibly being inserted into the component holding holes, whereby damage to the interiors of the component holding holes can be extremely diminished.Type: GrantFiled: October 9, 1998Date of Patent: April 10, 2001Assignee: Taiyo Yuden Co., Ltd.Inventors: Naoki Obana, Minoru Yuasa, Kazuo Naganuma

Patent number: 6210480Abstract: A device for wet coating, in particular printed circuit boards, with lacquer using at least one applicator roller (20, 21) and sparing at least one edge area of the printed circuit boards. The device uses a doctor blade arrangement situated between a lacquer reservoir and the printed circuit board that can move in an axial direction, one edge of which touches the applicator roller (20, 21). The doctor blade arrangement is designed can also remove excess lacquer, for example, photo-resistant lacquer from a multilayer board, from both longitudinal edges of the printed circuit board without any residue. This is also possible for multilayer boards of varying widths in particular.Type: GrantFiled: January 7, 1999Date of Patent: April 3, 2001Assignee: Robert Bürkle GmbHInventor: Josef Mai
