Patent number: 6523596Abstract: A method and apparatus for manufacturing a flexible curtain as disclosed and claimed. Edges of a polymeric material are folded back on themselves. A portion of the edges are secured and a portion is left unsecured or free. The flexible curtain is used in a windlocking apparatus to prevent the unwanted intrusion of wind, water and debris into a building opening. The free, or unsecured flap of the folded edge absorbs shock associated with storm disturbances. Edge rollers are used to laminate the edges of the curtains selectively such that only a portion of the edge is secured leaving the flap unsecured. Stitching, ultrasonic welding and gluing are alternative ways and/or additional ways of providing for the securement of a portion of the edge to itself. Perforations are made in the secured portion of the folded edge.Type: GrantFiled: August 23, 2000Date of Patent: February 25, 2003Assignee: Wayne-Dalton CorporationInventors: Willis Jay Mullet, Donald Bruce Kyle, Kelly Ray Green, Harry Edward Asbury

Patent number: 6491775Abstract: A method of adhesively bonding an adhesive coated, semi-rigid film to a substrate is reported. The method utilizes at least two alignment tools that are each positioned to substantially contact the surface of a substrate at an outer edge of the substrate. The adhesive-coated, semi-rigid film is then interposed between the first and the second alignment tools and the adhesive is brought into contact with the major surface of the substrate. The semi-rigid film is then aligned by contacting a first side edge of the semi-rigid film with a major surface of a first alignment tool and contacting a second side edge of the semi-rigid film with a major surface of a second alignment tool such that the film is aligned relative to the edge of the substrate. After alignment, pressure is applied to at least a portion of the surface area of the first side of the semi-rigid film to effectuate adhesive bonding of the film to the major surface of the substrate.Type: GrantFiled: June 27, 2000Date of Patent: December 10, 2002Assignee: 3M Innovative PropertiesInventors: Jeffrey Robert Janssen, William Frank Sheffield, Gary Mark Stucci

Patent number: 6474388Abstract: A device for binding a stack of media sheets using imaging material as the binding agent. The binding device includes a tray for supporting the stack and a heated platen or some other type of imaging material activator near the tray. A press coupled to the activator is operative between a first position in which the activator is separated from the stack to a second position in which the activator contacts and compresses the stack at the binding region. A spring or other biasing mechanism operatively connected between the press and the activator biases the activator against the stack when the press is in the second position. The biasing mechanism allows pressure to be maintained on the stack to reactivate the imaging material without continuing to power the press down against the stack even as the stack shrinks under the reactivating pressure. Hence, power can be diverted if necessary or desirable from the press to activator to reduce the overall power consumption of the binding device.Type: GrantFiled: March 22, 2001Date of Patent: November 5, 2002Assignee: Hewlett-Packard CompanyInventor: Roland Boss
