Patent number: 9034425Abstract: A method of dispensing adhesive onto a stretched elastic strand includes applying a first volume of adhesive onto a first portion of the elastic strand, applying a second volume of adhesive onto a second portion of the elastic strand, and applying a third volume of adhesive onto a third portion of the elastic strand. The second volume is less than the first and third volumes. When the elastic strand is adhered to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive to resist creep at the opposing ends. The reduction of adhesive in the second or central portion between the opposing ends significantly reduces the adhesive add on in the personal disposable hygiene product.Type: GrantFiled: April 11, 2012Date of Patent: May 19, 2015Assignee: Nordson CorporationInventor: Michael W. Harris

Patent number: 8961720Abstract: A method of bonding first and second strands onto a substrate traveling along a machine direction in a plane of travel. The method includes moving the first and second strands in the machine direction relative to a nozzle having a nozzle body with first and second liquid discharge passages, and first and second side-by-side notches. The first and second strands are guided for movement by engaging closed ends of the respective first and second notches. Open ends of the first and second notches are oriented or directed non-perpendicular to the plane of travel of the substrate. Liquid adhesive is dispensed onto the first and second strands from the liquid discharge passages and the first and second strands are bonded to the substrate.Type: GrantFiled: November 26, 2012Date of Patent: February 24, 2015Assignee: Nordson CorporationInventors: Michael W. Harris, Alan Ramspeck

Publication number: 20140345786Abstract: A method of dispensing adhesive onto a stretched elastic strand includes applying a first volume of adhesive onto a first portion of the elastic strand, applying a second volume of adhesive onto a second portion of the elastic strand, and applying a third volume of adhesive onto a third portion of the elastic strand. The second volume is less than the first and third volumes. When the elastic strand is adhesively secured to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive capable of limiting movement of the strand at the opposing ends, thereby maintaining the integrity of the bond between the substrate and the elastic strand.Type: ApplicationFiled: August 11, 2014Publication date: November 27, 2014Inventors: Michael W. Harris, Joel E. Saine

Publication number: 20140314956Abstract: A liquid dispensing module and nozzle or die tip for discharging at least one liquid filament. The nozzle includes a strand guide for guiding a substrate past the nozzle and a frustoconical protrusion disposed on a surface of the nozzle adjacent the notch. A liquid discharge passage extends along an axis through the frustoconical protrusion and forms an acute angle with a machine direction corresponding to movement of the strand past the nozzle. Four air discharge passages are positioned at the base of the frustoconical protrusion. Each of the air discharge passages is angled in a compound manner generally toward the liquid discharge passage and offset from the axis of the liquid discharge passage to create the controlled pattern of liquid material on the strand.Type: ApplicationFiled: July 1, 2014Publication date: October 23, 2014Inventors: Patrick L. Crane, Michael W. Harris, Joel E. Saine
