Abstract: Specialized sheets, for example, in the construction of business forms, having patterns of pressure activated cohesive are constructed so that all the sheets can be identical yet when the sheets are in a stack blocking of the pressure activated cohesive, and subsequent feeding problems, are eliminated by making the cohesive patterns offset a dimension "d" perpendicular to the direction of feed of the forms from a feed bin through an imaging device to an output tray. Either the feed bin, or an edge guide of the output tray, can be shifted at least the dimension "d" to automatically align the pressure activated cohesive patterns on cooperating first and second sheets, and after proper alignment of the cohesive patterns the sheets may be fed through a conventional pressure sealer.

Abstract: A method of manufacturing a flat display panel having first and second substrates assembled in spaced relationship with a gap therebetween and joined together by a band of sealing material, formed in a frame configuration which may be rectangular, on the surface of the first substrate and adhering the first and second substrates together. A paste of the sealing material is dispensed from a nozzle moved along a route from a starting point displaced the frame configuration, thereby forming a starting segment extending from the starting point to the frame, along the route of the rectangular frame configuration and forming a central segment, and from the frame and to the ending point thereby forming an ending segment integral with the central segment, the ending point being displaced from the frame configuration and from the starting point.

Abstract: A device for applying a vapor retarder film onto purlins on a roofing system has a base with rollers and guides for directing the base across the purlins. The base has a fore end and an aft end with a pair of side members. The base moves across the purlins such that the side members remain in a fixed spaced apart relationship wider than the spacing between the pair of purlins. A vertical member attached to each of the side members provides a means for mounting a web of the vapor retarder film on a roll above the base and the adjacent pair of the spaced apart purlins. Adhesive is dispensed onto the edges of the web and the web is payed out and guided onto the purlin so that the edge of the web having the adhesive is put into adhesive engagement with the top surface of the purlins and the film sealingly spans the interval between the adjacent purlins. By use of a plurality of these devices acting in parallel, a method of applying the web to the roof purlins is taught.

Abstract: A method and apparatus for bonding a cover (22) over the undulating surface of a foam cushion (10) by placing the foam cushion (10) on a tool (18), piercing the cushion (10) with a plurality of needles (44), lifting the needles (44) to lift the cushion (10) as the cushion is frictionally retained on the needles (44), heating ambient air and ejecting the hot air from the needles (44) and into the cushion to elevate the temperature of the cushion. A compression plate (58) with holes (60) extending therethrough is disposed against the backside of the cushion (10) with the needles (44) extending through the holes (60). The needles (44) with the cushion (10) thereon are lowered to place the undulating surface of the cushion against an adhesive film (82) on the backside of the cover (22) so that heat is transferred from the cushion (10) to melt the adhesive.
