A non-flame retardant, pressure sensitive adhesive is applied the support surface.

Abstract: A system controls the flow of a conductive fluid after the fluid is coated onto a substrate by applying an electrostatic force to the coated fluid. The force applied to the fluid can be controlled to counteract the fluid tendency to dewet to a thicker state if significant interfacial surface tension differences exists between the fluid and substrate.

Abstract: A roll supporting hub is adapted for acceptance of a plurality of rolls (one at a time), with each roll having a different predefined core width. The hub includes a hub body with a plurality of core support surfaces spaced circumferentially about a central rotation axis. One or more of those surfaces engage the core of the roll to secure the roll and hub together for coupled rotation. A stop surface on the hub body engages a first radial side of the core, while a radially retractable retainer surface engages a second radial side of the core. The retainer surface is secured to the hub body in one of a plurality of possible predefined axially disposed positions relative to the stop surface, each of which corresponds to one of the predetermined core widths of the roll being supported by the hub. The retainer surface is supported by a spring which is retractable within a slot extending axially between opposed support surfaces on the hub body.

An affixation member fixedly supporting the interengaging fastener member is molded in the cavity of the body mold. The body mold is separated from the molded affixation member, and the stem mold is destructibly removed from the interengaging fastener member fixedly supported on the molded affixation member.

Abstract: Methods of finishing and microfinishing the edges of a die component are disclosed. Each edge is polished to finish the edge of the die component to a smoother finish than the rest of the die component. This eliminates the incidence of undesirable streaking defects in the coating. The grinding and polishing includes placing a grind fixture adjacent the die component contiguous with the edge to present a grind fixture surface coplanar with the first surface of the edge, then grinding and polishing together the first surface of the edge of the die component and the adjacent grind fixture surface are polished. This is repeated for the second surface of the edge.

Abstract: A masking tape is provided that is suitable for insertion under many moldings and gaskets which not only masks the molding or gasket but also facilitates refinishing under at least a portion of the molding or gasket. The masking tape is constructed to include a longitudinal non-adhesive portion and a longitudinal adhesive portion, wherein the non-adhesive portion is stiffer than the adhesive portion and is sufficiently stiff to facilitate easy insertion of the non-adhesive portion beneath at least a portion of the molding or gasket to be masked while the adhesive portion is sufficiently flexible to permit the wrapping thereof around the molding or gasket. The stiffened portion advantageously provides a dual purpose of facilitating the easy insertion of the non-adhesive portion beneath the molding or gasket and creating a lever action during application between the molding or gasket and the wall or panel to which the molding or gasket is mounted.

Abstract: A rotary acoustic horn imparts energy at a selected wavelength, frequency, and amplitude. The horn includes a base portion and a plurality of weld faces. Each weld face has a diameter that expands and contracts with the application of ultrasonic energy. The weld faces are spaced from each other and are mounted in one of series and parallel with each other.

Abstract: A water-based pressure sensitive adhesive formulation is provided with one or more high molecular weight linear aliphatic polymers. The resulting composition can be used to form stable filaments or delivered from the coating die of a premetered coater in the form of a stable sheet at a flow rate substantially less than the minimum delivery flow rate achievable using the formulation without polymer. Low levels of polymer can provide dramatic improvement in the viscosity of such compositions, without detrimental effect on the adhesive and other desireable qualities of the composition.

Abstract: A system for coating a substrate with an ultra-thin layer includes moving the substrate through a coating station and forming a composite layer including a coming fluid and a carrier fluid. The composite layer flows at a rate that is sufficiently high to form a continuous flowing fluid bridge of composite layer to the substrate surface and to contact the substrate with the flowing composite layer to interpose the coating layer between the substrate and the carrier fluid. The carrier fluid is removed while leaving the coating fluid deposited on the substrate as a coating layer.

Abstract: A die coating method and apparatus includes a die having an upstream bar with an upstream lip and a downstream bar with a downstream lip. The upstream lip is formed as a land and the downstream lip is formed as a sharp edge. The shape of the land conforms to the shape of the surface being coated. Changing at least one of the slot height, the overbite, and the convergence can improve coating performance. A replaceable, flexible strip can be used above the coating slot to facilitate replacement of a damaged overbite edge. The strip can be held in position by vacuum applied through the downstream bar.

Abstract: A coater incorporates a die, a reservoir, a gravure cylinder, and a doctor blade for applying coating fluid to a moving surface. The flow rate of coating fluid to the gravure cylinder is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. The coating fluid can be quickly and conveniently replaced with a solvent in the reservoir when coating is not being performed to reduce the occurrence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid.

Abstract: A fastener member is disclosed, having a plurality of headed stems adjoining and projecting from a base. The headed stems are arranged in a pattern on the base, which pattern tends to increase the disengagement force in the shear direction.

Abstract: A cross flow knife coater includes a coating station through which a surface passes and a trough which extends transversely across the desired width of the coating. The trough has an opening through which coating fluid exits onto the surface without using a slot, and first and second transverse ends. The coating fluid is fed directly into the trough at a first transverse end, and is moved from the first transverse end of the trough, across the trough, and toward the second transverse end to cause the coating fluid to flow across the width of the trough while coating fluid exits the opening. The coater creates a spiral flow of coating fluid across the width of the trough which carries debris, bubbles, and other undesirables across the trough to a second traverse end where they can be vented. The perpendicular distance between the trough opening and the surface, and likewise between the knife and the surface, can be adjusted.

Abstract: A continuous tape supply apparatus is provided which includes plural tape sources from which tape can be supplied to the tape applicator machine, a tension control means for providing the tape from the continuous tape supply apparatus at a substantially even tension under an indexing demand, and a splicing mechanism which is simpler in design and operation and which reliably causes a changeover of tape from one source to another. Once one source is depleted, the apparatus automatically switches to the second source, after which, a new supply can be substituted for the depleted supply and the apparatus made ready for the next subsequent changeover.
