20090065611 | LIQUID DISPENSER HAVING INDIVIDUALIZED PROCESS AIR CONTROL - A dispenser for dispensing liquid material while attenuating the liquid material or controlling the pattern of the liquid material with process air has a plurality of process air passages for providing process air to one or more liquid dispensing modules or nozzles. The flow rate of process air provided to one or more of the modules or nozzles may be separately controlled to be different from the flow rate provided to other modules or nozzles on the dispenser. Accordingly, the flow rate provided to each module or nozzle can be optimized to accommodate a particular dispensing nozzle or die. | 03-12-2009 |
20090206506 | MODULE, NOZZLE AND METHOD FOR DISPENSING CONTROLLED PATTERNS OF LIQUID MATERIAL - 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. | 08-20-2009 |

20100327074 | METHOD FOR DISPENSING RANDOM PATTERN OF ADHESIVE FILAMENTS - A nozzle for dispensing a random pattern of liquid adhesive filaments. The nozzle may include first and second air shim plates, an adhesive shim plate and first and second separating shim plates. The first and second air shim plates each have respective pairs of air slots. Each air slot has a process air inlet and a process air outlet and the air slots of each pair converge toward one another such that the process air inlets are farther apart than the process air outlets in each pair. The adhesive shim plate includes a plurality of liquid slots each with a liquid outlet. Four process air outlets are associated with each of the liquid outlets. The process air slots are adapted to receive pressurized process air and the liquid slots are adapted to receive pressurized liquid adhesive. The pressurized process air discharges from each group of the four process air outlets and forms a zone of turbulence for moving the filament of liquid adhesive discharging from the associated liquid outlet in a random pattern. | 12-30-2010 |

20120258246 | SYSTEM, NOZZLE, AND METHOD FOR COATING ELASTIC STRANDS - A contact nozzle for coating an elastic strand with an adhesive. Air is discharged at the adhesive in contact with the strand, causing the adhesive to spread around the periphery of the strand. The air assists with release of the adhesive from the nozzle and also cleans the nozzle to discourage adhesive build-up on the nozzle. | 10-11-2012 |

20140345786 | METHOD FOR APPLYING ADHESIVE ON AN ELASTIC STRAND IN ASSEMBLY OF A PERSONAL DISPOSABLE HYGIENE PRODUCT - 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. | 11-27-2014 |
20140361203 | PNEUMATICALLY ACTUATED LIQUID DISPENSING VALVE - A liquid dispensing valve includes a liquid inlet for receiving the liquid and a liquid outlet for discharging the liquid. A valve member is mounted for movement relative to the liquid outlet between open and closed positions. A liquid passage communicates between the liquid inlet and the liquid outlet. An air inlet is provided for receiving air from a source of pressurized air. An air passageway is coupled with the air inlet. A pneumatic actuator communicates with the air passageway for moving the valve member at least to the open position. An electrically operated air supply device interacts with the air passageway so as to control the flow of pressurized air to the pneumatic actuator. | 12-11-2014 |
