Embodiment Construction

[0041] figure 1 and figure 2 One embodiment of a nozzle 10 for dispensing a random pattern (not shown) of liquid adhesive filaments is shown. As will be discussed in more detail below, the nozzle 10 is configured such that pressurized process air is directed towards the liquid adhesive filaments in an asymmetric manner. This general principle can be incorporated into a wide variety of adhesive dispensing systems. Thus, although the construction of the nozzle 10 will be described in considerable detail, those of ordinary skill in the art will appreciate that the nozzle 10 is merely how the components may be arranged or the solid nozzle may be drilled to achieve the asymmetries described below. An example of a layout.

[0042] The nozzle 10 includes a nozzle body 12 and a first end plate 14 and a second end plate 16 secured to the nozzle body 12 . The nozzle body 12 has a generally triangular or wedge-shaped cross-sectional shape with a first surface 20 and a second surface...

Abstract

The present invention relates to a nozzle and a method for dispensing random pattern of adhesive filaments. The nozzle for dispensing a random pattern of liquid adhesive filaments generally comprises an adhesive shim plate positioned between first and second air shim plates. The first air shim plate includes air slots configured to direct pressurized process air along a first angle relative to theadhesive shim plate, and the second air shim plate includes air slots configured to direct pressurized process air along a second angle relative to the adhesive shim plate. The first angle is different than the second angle so that the first and second air shim plates direct the pressurized process air asymmetrically toward adhesive filaments discharging from liquid slots in the adhesive shim plate.

Description

technical field [0001] The present invention relates generally to air-assisted nozzles and systems for extruding and moving filaments of viscous liquids in a desired pattern, and more particularly to air-assisted dispensing of filaments of hot melt adhesives. Background technique [0002] Various dispensing systems have been used in the past for applying patterns of various viscous liquid materials, such as hot melt adhesives, to moving substrates for a wide range of manufacturing targets, including but not limited to packaging, various product Components, and construction of disposable absorbent hygiene products. Thus, the dispensing system described is used in the production of disposable absorbent hygiene products such as diapers. In the production of disposable absorbent hygiene products, hot melt adhesive dispensing systems have been developed for the application of hot melt thermoplastic adhesives between nonwoven fibrous layers and thin polyethylene backsheets Lamin...
