  • Patent number: 7588716
    Abstract: A peripheral layer forming apparatus for coating a pillar-shaped member with a peripheral layer. The apparatus includes supporting members configured to sandwich the member from both sides and support the member so that an axis of the member is maintained in a horizontal orientation. A peripheral layer forming head is provided having a squeegee with a face configured to be oriented parallel to the axis. The apparatus is configured to provide the face at a predetermined angle with respect to a virtual face, where the virtual face is defined as a plane that is parallel to the axis of the member and that is tangential to a contact point on a peripheral face of the member where the squeegee is configured to contact the member. The apparatus is configured to maintain the predetermined angle as a peripheral layer is formed on the peripheral face of the member by a movement of at least one of the squeegee and the member.

  • Patent number: 7575778
    Abstract: The present invention teaches formulations, apparatus and a method of applying high thixotropic index polymer thick-film resistive pastes for making polymer thick-film resistors with improved tolerances by providing a squeegee with a blade tilted at an angle of 10° to 85° to the surface of the printed circuit board thus causing a fluid rotational motion within the bead of the polymer thick-film resistive paste as the squeegee blade moves relative to the printed circuit board. This rotational motion increases the shear strain rate experienced by the paste within the bead and results in a more effective filling of the resistor-shaped cavity without including air bubbles, experiencing elastic recovery of the paste and, without surface fractures of the paste.

  • Publication number: 20090176025
    Abstract: A drywall hopper assembly that contains a double blade that can apply drywall mud to both interior and exterior drywall corners with no blade change. A zigzag blade can contain two grooves, one for interior corners and one for exterior corners. With this blade arrangement, an operator can quickly move from one type of corner to another without using multiple tools, multiple blades or hand application methods to apply mud. The present invention can contain a pliable release port to present mud equally to an interior or an exterior corner. There can be such a port on both the top and bottom of the blade so that mud is smoothly applied as trim moves through the hopper or the hopper is moved along the trim.

  • Publication number: 20090053418
    Abstract: According to the coating method of the present invention, the uneven portion on the land of the upstream side makes it possible to increase a contact area between the coating solution and the land, thereby improving the stability of a bead. In other words, according to the coating method of the present invention, it is possible to improve the stability of a bead on the upstream side, the stability having been reduced by the overbite shape of the die. Thus, even when a coating solution having a low viscosity of 10 cp or less is applied with a small coating amount of 10 cc/m2 or less, it is possible to increase the speed of the web without causing an uneven coating.

  • Patent number: 7029726
    Abstract: The systems, methods and products of the invention include systems and methods for manufacturing servo tracks on a magnetic tape. In one aspect, the invention includes systems for manufacturing magnetic tapes having servo tracks thereon wherein the servo tracks are optically detectable and are capable of being processed by a servo control system for maintaining alignment of a magnetic recording head with the data tracks on the recording side of the magnetic tape. In one practice, the manufacturing systems described herein engrave the servo tracks onto the non-recording side of a magnetic tape by directing a laser beam at the non-recording side of the magnetic tape. In another practice, the manufacturing systems described herein engrave the servo tracks onto the magnetic side of a magnetic tape by directing a laser beam at the magnetic side of the magnetic tape. Such engraved patterns can act as optical servo tracks for maintaining alignment of the recording head with the data tracks on the magnetic tape.

  • Patent number: 7022380
    Abstract: Method and apparatus for coating a traveling paper web includes a coater head. The coater head includes an inlet for receiving fresh coating material which is introduced into a mixing chamber. A looped flow path is established within the coater head which includes a feed channel extending from the mixing chamber and leading into a coating chamber where one portion of the coating material proceeds in the direction of the rotating backing roll. The aqueous slurry of coating material near the downstream end of the coating chamber enters a recirculation channel from which it is directed through a plurality of flow metering orifices back into the mixing chamber.

  • Patent number: 6984412
    Abstract: The present invention provides a method for removing wrinkles formed on a web, which is continuously transported through a plurality of guide members. The plurality of guide member includes a crown roller which has the diameter gradually increased toward the center thereof. The crown roller is placed in a transport path of the web and downstream of a first zone in which wrinkles are desirably removed, and the web is deformed in a second zone located downstream of the crown roller so as to at least decrease the width of the web, whereby the wrinkles in the first zone are removed. Even when the web is thin (10 ?m or less), without using particular backup means, wrinkles formed during transport and coating of the web can be removed. In addition, since wrinkles are appropriately removed, a coating film having a uniform thickness can be obtained by an extrusion coating method.

  • Patent number: 6908641
    Abstract: The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.

  • Patent number: 6896971
    Abstract: A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a different substance. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel.

  • Patent number: RE40857
    Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.
