Embodiment Construction

[0061] figure 1 A contact nozzle 2 configured for use in an adhesive dispensing system according to the invention is shown. The contact nozzle 2 receives the stretched elastic strand 12 and applies adhesive 14 to the elastic strand 12 by contacting the coated elastic strand 12 as the elastic strand 12 moves in the machine direction indicated by arrow 16. Line 12. The contact nozzle 2 is shown in this figure as a generalized contact nozzle 2 and it is understood that any form and any specific shape of the contact nozzle may be used in accordance with the principles of the present invention. Pressurized air (hereinafter “air”) is then vented at the adhesive 14 on the elastic strand 12 downstream of the application of the adhesive 14 (with respect to the machine direction 16 ), as indicated by arrow 18 . Although the air flow originates from the figure 1 Arrow 18 at the contact nozzle 2 in , but it should be understood that in other embodiments within the scope of the inventi...

Abstract

A system, nozzle and method for coating elastic stranded wire. The nozzle is a contact nozzle (2) for coating the elastic strand (12) with an adhesive (14). expelling air (18) at said adhesive (14) in contact with said strands (12), causing said adhesive (14) to spread around the perimeter of said strands (12) . The air (18) assists the release of the adhesive (14) from the nozzle (2) and also clears the nozzle (2) to prevent adhesive build-up on the nozzle (2).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to (pending) US Provisional Patent Application No. 61 / 474,129, filed April 11, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to fluid dispensing systems, nozzles and methods for applying adhesive to one or more strands of stretch elastic material. Background technique [0004] During the manufacture of disposable hygiene products such as diapers, adult incontinence products and feminine hygiene products, liquid adhesives such as temperature sensitive adhesives and / or pressure sensitive adhesives are applied to one or more strands of elastic material Stretched strands or nonwoven substrates to form various elastic structures as part of hygiene products. For example, in a diaper, one or more stretched elastic strands are incorporated between the back and top panels surrounding the leg openings so that the...
