Abstract
Abstract The invention relates to an apparatus and method of controlling the generation of somewhat-to-highly viscous fluid fibers, droplets and combinations of the same, including hot melt adhesive and other fluids, that comprises, spraying a stream of such pressurized fluid through a fine orifice and along a predetermined direction in free flight, and simultaneously funneling a cone of pressurized air symmetrically about and against said stream, intersecting the same in its free flight below said orifice to control the nature, dimensions and pattern of the resulting fluid coating on surfaces disposed therebelow. Supplemental air controls are also providable for contouring and other effects.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
28 words
A product having a substrate upon which a single continuous fiber has been extruded in a random nondescript laterally criss-cross pattern layer at each of selected regions thereof.
Claim 2
Dependent Claim
28 words
A product having a substrate upon which a single continuous fiber has been extruded in a random nondescript laterally criss-cross pattern layer at each of selected regions thereof.
Claim 3
Dependent Claim
23 words
A product as claimed in claim 1 and in which the crisscross pattern layer provides for reinforcement of the substrate at such regions.
Claim 4
Dependent Claim
55 words
A product as claimed in claim 1 and in which the fibers are of hot melt material and the substrate is of diaper and/or feminine napkin material and the crisscross pattern layer is contoured at the selected regions including one of internal continuous pattern, contoured side pattern, and intermittent band pattern including transverse end stripes.
Claim 5
Dependent Claim
61 words
A product as claimed in claim 1 and in which the fibers are of hot melt adhesive and the crisscross pattern layer has been deposited in low coat weight of the order of a fraction of a gram to a few grams per square meter, and with the crisscross pattern layer providing adhesive holding power comparable to heavier full width coatings.
Claim 6
Dependent Claim
15 words
A product as claimed in claim 4 and in which the substrate is a tape.
Claim 7
Dependent Claim
28 words
A product as claimed in claim 4 and in which the substrate is a breathable tape or bandage and the said crisscross pattern layer is open or breathable.
Claim 8
Dependent Claim
25 words
A product as claimed in claim 6 and in which the substrate carries a breathable silicone pattern on the surface opposite the crisscross pattern layer.
Claim 9
Dependent Claim
37 words
A product as claimed in claim 1 and in which the substrate is at least one of breathable fabrics including non-woven porous sheets and tissues, impermeable sheets of polyethylene, polypropylene and polyvinyl chloride, and thermally bonded polypropylene.
Claim 10
Dependent Claim
53 words
A product having a substrate upon which multiple fluid components have been extruded, in at least some of which a single continuous fiber forms a random nondescript laterally crisscross pattern layer, said components being mixed for enabling at least one of catalytic reaction and cross-linking, including, if desired, subsequent radiation-induced cross-linking and curing.
Claim 11
Dependent Claim
53 words
A product having a substrate upon which multiple fluid components have been extruded, in at least some of which a single continuous fiber forms a random nondescript laterally crisscross pattern layer, said components being mixed for enabling at least one of catalytic reaction and cross-linking, including, if desired, subsequent radiation-induced cross-linking and curing.
Claim 12
Dependent Claim
31 words
A product as claimed in any preceding claim in which a member is secured to said substrate by said fibers serving as an adhesive connection between said substrate and said member.
