Patent number: 5750444Abstract: A breathable laminate comprises at least two porous webs laminated together with a porous adhesive matrix, preferably a random fibrous adhesive pattern having a coat weight of between 1.5 and 12 grams per square meter. The two or more porous webs comprise woven or non-woven materials and the resulting breathable fabric or laminate has good hand and flexibility. Breathable fabric is adhered to foam by such random fibrous adhesive patterns of similar coat weights. Coating widths of up to 80 inches or more are produced in a slot die fed by a selected plurality of recessed lands within the die, with motors and pumps controlled to maintain consistent, uniform coat weights regardless of coat widths and substrate speeds selected. Single ply coated webs, apparatus and methods are disclosed.Type: GrantFiled: October 4, 1993Date of Patent: May 12, 1998Assignee: Nordson CorporationInventors: Curt Jarrell, Manfred Kubo, Hans-Jurgen Meissner, Gustav Rieckmann, Jurgen Benecke

Patent number: 5733597Abstract: Coating dispenser apparatus and methods which utilize a snuff back device for removing a small amount of coating material from the discharge passage of the dispenser upon shut-off thereof at the end of a coating run. A control is provided which discharges the material removed from the discharge passage back into the discharge passage upon a predetermined delay after the start of the next coating run. The disclosed methods contemplate the discharge of coating material back into the discharge passage in the middle of the next coating pattern, or depending on the application, during any segment of the next coating pattern after a defined leading edge of the pattern is created, during which segment the coating material discharged back into the discharge pattern smoothly blends into the coating pattern as it is applied to a substrate. The apparatus and methods are especially useful for applying conformal coating patterns onto circuit boards.Type: GrantFiled: April 3, 1995Date of Patent: March 31, 1998Assignee: Nordson CorporationInventors: James W. Schmitkons, James Turner, Marcus P. Zupan, Antonio Rivas, Jurgen Benecke, Arthur Cieplik, Thomas Burmester, Bentley Boger

Patent number: 5720820Abstract: Apparatus for producing intermittent, discrete patterns of coating material onto discrete irregular substrate areas, such as electronic circuit boards, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the coating material flow. Also, the air flow is continued beyond that point in time, when the coating material flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the circuit board. The air flow carries the film coating material to the circuit board for deposition in discrete areas thereon.Type: GrantFiled: February 13, 1995Date of Patent: February 24, 1998Assignee: Nordson CorporationInventors: Bentley Boger, Jurgen Benecke, Arthur Cieplik, Thomas Burmester, Michael L.

Patent number: 5685911Abstract: Apparatus for producing intermittent, discrete patterns of coating material, such as hot melt adhesive, onto discrete substrates or substrate areas, such as book spines, sift-proof carton flaps and pinch-bottom bags. The adhesive patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow. Also, the air flow is continued beyond that point in time, when the hot melt flow ceases. The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds. Coating weights down to 1 gram per square meter at about 350 meters per minute substrate speed are provided.Type: GrantFiled: January 27, 1995Date of Patent: November 11, 1997Assignee: Nordson CorporationInventors: John Raterman, Jurgen Benecke, Arthur Cieplik, Thomas Burmester, Michael L.

Patent number: 5524828Abstract: Apparatus for producing intermittent, discrete patterns of foam coating material, onto discrete substrates or substrate areas, where the patterns have sharp, square leading and trailing edges, as well as side edges. A slot nozzle die has elongated air slots along the slot extrusion opening. Air flow is initiated from both air slots prior to the initiation of the foam flow. Also, the air flow is continued beyond that point in time when the foam flow ceases. The delays between the operations of the air flow and the foam coating flow are on the order of micro seconds. Alternatively, the lead and lag air start and stop times on each side of the foam coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate.Type: GrantFiled: March 8, 1995Date of Patent: June 11, 1996Assignee: Nordson CorporationInventors: John Raterman, Jurgen Benecke, Arthur Cieplik, Thomas Burmester, Michael L.

Patent number: 5421921Abstract: A slot die for producing a fibrous web of adhesive material includes a segmented shim having a plurality of fingers in said slat dividing adhesive material into a plurality of adhesive streams. The fingers have tapered ends which are flush with or extend slightly beyond the slot nozzle outlet. Separate material streams emanate from the slot nozzle outlet where they merge and are engaged by air flow producing a fibrous web of adhesive material. The adhesive and air flow are started and stopped at intervals to produce discrete fibrous webs having square, sharp leading and trailing edges.Type: GrantFiled: July 8, 1992Date of Patent: June 6, 1995Assignee: Nordson CorporationInventors: Michael L.

Patent number: 5354378Abstract: Apparatus and methods for producing coatings, such as wax or hot melt adhesive, onto the tops and necks of wine bottles or similar objects. A slot nozzle die has elongated air slots along a vertically oriented slot extrusion opening. A hot melt or wax gun is disposed above the bottle neck to apply a bead of adhesive to the bottle top. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow and is continued beyond that point in time, when the hot melt flow ceases. The air carries a film of coating material horizontally to the bottle neck. Means are provided for spinning the bottle about its vertical axis. The delays between the operations of the air flow and the coating flow are on the order of micro seconds. The merged coatings are heated to smooth the coating finish to produce a traditional neck seal.Type: GrantFiled: July 8, 1992Date of Patent: October 11, 1994Assignee: Nordson CorporationInventors: Larry Hauser, Jurgen Benecke, Arthur Cieplik, Thomas Burmester, Michael L.
