Abstract
Abstract A continuous method for bonding or seaming running webs wherein a moving arcuate surface serves as an anvil against which a sonic horn can work while at the same time supplying a bonding medium to the webs as they pass under the horn, and to apparatus for carrying out such a method. In one embodiment, the arcuate surface is designed to provide a seam which simulates a series of stitches.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
104 words
A method of bonding webs which comprises forwarding a plurality of webs to a zone wherein localized sonic energy may be applied positioning a moving arcuate surface against one of the webs to serve as an anvil against which the sonic energy can work, supplying predetermined amounts of a bonding medium to the moving arcuate surface applying localized sonic energy in said zone, transferring the bonding medium carried by the arcuate surface to the webs as the localized sonic energy is applied in said zone to set said bonding medium and thereby bond together said webs, and removing the bonded webs from the zone.
Claim 2
Independent Claim
104 words
A method of bonding webs which comprises forwarding a plurality of webs to a zone wherein localized sonic energy may be applied positioning a moving arcuate surface against one of the webs to serve as an anvil against which the sonic energy can work, supplying predetermined amounts of a bonding medium to the moving arcuate surface applying localized sonic energy in said zone, transferring the bonding medium carried by the arcuate surface to the webs as the localized sonic energy is applied in said zone to set said bonding medium and thereby bond together said webs, and removing the bonded webs from the zone.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein the moving arcuate anvil surface intermittently contacts the web so that said bonding medium is transferred to said web in a predetermined pattern.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein the moving arcuate surface is substantially in continuous contact with the web.
Claim 5
Dependent Claim
34 words
The method of claim 1 wherein the localized sonic energy is applied by a horn, the webs are passed between the horn and the moving arcuate anvil surface, and the bonding medium is water.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein the bonding medium is an adhesive.
Claim 7
Dependent Claim
16 words
The method of claim 1 wherein at least one of the webs is a nonwoven material.
Claim 8
Dependent Claim
19 words
The method of claim 1 wherein the zone of sonic energy provides at least about 20,000 cycles per second.
Claim 9
Independent Claim
122 words
A method of bonding a web formed from discrete elements which comprises forwarding the web to a plurality of zones spatially disposed across the lateral dimension of the web wherein localized sonic energy may be applied, positioning a moving arcuate surface in each zone and against the web to serve as anvils against which sonic energy can work, supplying predetermined amounts of a bonding medium to each of the moving arcuate surfaces, applying localized sonic energy in said zones, transferring the bonding medium carried by the arcuate surfaces to the web as the localized sonic Energy is applied in said zone to set said bonding medium and to thereby bond the discrete elements together and removing the bonded web from the zone.
Claim 10
Independent Claim
122 words
A method of bonding a web formed from discrete elements which comprises forwarding the web to a plurality of zones spatially disposed across the lateral dimension of the web wherein localized sonic energy may be applied, positioning a moving arcuate surface in each zone and against the web to serve as anvils against which sonic energy can work, supplying predetermined amounts of a bonding medium to each of the moving arcuate surfaces, applying localized sonic energy in said zones, transferring the bonding medium carried by the arcuate surfaces to the web as the localized sonic Energy is applied in said zone to set said bonding medium and to thereby bond the discrete elements together and removing the bonded web from the zone.
Claim 11
Dependent Claim
41 words
The method of claim 1 wherein the moving arcuate anvil surface is positioned so that said moving arcuate anvil surface supports the web and transfers the bonding medium to the web as the localized sonic energy is applied in said zones.
