Publication number: 20210285804Abstract: A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.Type: ApplicationFiled: June 1, 2021Publication date: September 16, 2021Inventors: Wesley C. Fort, Ronald Ramspeck, Enes Ramosevac

Patent number: 9283120Abstract: A system and method applies a plurality of stretched elastic strands onto a substrate such as along a predetermined non-linear path, to form a leg gather of a disposable absorbent personal hygiene product. The system includes an adhesive dispensing module for individually applying adhesive to the elastic strands. A heated strand guide located downstream of the dispensing module includes guide openings for the respective elastic strands. A drive mechanism coupled to the strand guide actuates movement of the strand guide in a direction transverse to the movement direction of the substrate, thereby causing the elastic strands to be applied to the substrate along the predetermined non-linear path.Type: GrantFiled: March 31, 2014Date of Patent: March 15, 2016Assignee: NORDSON CORPORATIONInventor: Wesley C.

Patent number: 8753713Abstract: Jetting dispensers and methods of non-contact dispensing a hot melt adhesive onto a substrate. The method may include jetting a plurality of droplets of the hot melt adhesive from a nozzle outlet toward the substrate in a direction of travel. Each droplet has a droplet length approximately aligned with the direction of travel and a droplet width shorter than the droplet length. The jetting is controlled such that each of the droplets does not collapse into a spherical-shaped droplet during flight from the nozzle outlet to the substrate. The nozzle outlet may be heated to a first temperature, and the method may further include rapidly heating each droplet of the hot melt adhesive to a second temperature higher than the first temperature upon release from the nozzle outlet.Type: GrantFiled: June 2, 2011Date of Patent: June 17, 2014Assignee: Nordson CorporationInventors: Justin A.

Patent number: 8439226Abstract: A dispensing valve is provided for dispensing liquid from a cartridge. The valve includes a valve body that is adapted to receive at least a portion of the cartridge therein. A valve member is disposed in the valve body and is adapted for fluid communication with the cartridge. A valve seat element is disposed in the valve body and includes a liquid chamber that is in communication with the liquid outlet and is mounted for reciprocating movement between a closed position engaged with the valve member to prevent liquid from exiting the liquid outlet and an open position disengaged from the valve member to allow liquid to flow from the liquid chamber through the liquid outlet.

Patent number: 8016734Abstract: Various methods of forming bags include applying hot melt adhesive to material without contacting the material with the dispenser that applies the adhesive. The material may be provided in various forms, such as elongate sheet material dispensed from a roll, or elongate tube material that is flattened to define first and second oppositely disposed sidewalls, for example. The material may be provided in single plies, multiple plies, or as separate sheets that are cut, folded, or otherwise manipulated to form bags, with the adhesive joining selected portions of the bag. A nozzle for dispensing hot melt adhesive includes an air passage that is inclined in a direction toward a liquid outlet. The air passage communicates with an air outlet disposed in a common plane with the liquid outlet.Type: GrantFiled: March 10, 2008Date of Patent: September 13, 2011Assignee: Nordson CorporationInventor: Wesley C.
