Abstract
Official abstract text for this publication.
Using electrostatic means, such as plasma, webs can be cut, and webs can be bonded together. A plasma is created and directed at an intervening poly or a nonwoven to sever the fabric, either continuously or intermittently, or to bond and sever two more material layers together.
First claim
Opening claim text (preview).
We claim: 1 . A method for processing webs of material, the system comprising: providing at least one web of nonwoven material into a web processing system; supplying an anode and a cathode and a plasma between said anode and cathode; and passing said at least one web of material through said plasma to process said at least one web of nonwoven material by bonding individual fibers of said nonwoven web of material; creating a disposable product at least in part from said at least one web of nonwoven material. 2 . A method according to claim 1 , said method further comprising carrying at least one of said anode and said cathode on a first rotating body, carrying at least one of said anode and said cathode on a second rotating body and passing said at least one web through said plasma between said first and second rotating bodies. 3 . A method according to claim 2 , said plasma being generated between a first raised surface and a second raised surface, wherein the first raised surface is on one of said first and second rotating bodies and the second raised surface is on the other of said first and second rotating bodies. 4 . A method according to claim 2 , said method further comprising severing a discrete piece from said at least one web of nonwoven material and drawing said discrete piece into at least one of said first and said second rotating bodies.
