A bonding system for bonding a web comprising at least a pair of web layers , the bonding system comprising: a first ultrasonic horn ; and a first anvil spaced apart from the first ultrasonic horn by a gap so as to allow for translation of the web therethrough in a machine direction, wherein the first anvil includes an anvil insert comprising a pair of seal surfaces extending in a cross-machine direction that is orthogonal to the machine direction and being spaced apart in the machine direction so as to have a recess therebetween; wherein each of the pair of seal surfaces comprises canted teeth formed thereon, the canted teeth angled so as to provide both trailing edge and leading edge coverage in the cross-machine direction; wherein the first ultrasonic horn operates with the first anvil to ultrasonically bond the plurality of web layers together at a plurality of bond points corresponding to the canted teeth , as the web moves through the gap; the bonding system further comprising: a second ultrasonic horn ; and a second anvil spaced apart from the second ultrasonic horn by a gap so as to allow for translation of the web therethrough in the machine direction; wherein the second anvil includes another anvil insert comprising another pair of seal surfaces extending in the cross-machine direction and spaced apart in the machine direction so as to have a recess therebetween; wherein each of the pair of another pair of seal surfaces comprises canted teeth formed thereon angled so as to provide both trailing edge and leading edge coverage in the cross-machine direction; wherein the second ultrasonic horn operates with the second anvil to ultrasonically bond the plurality of web layers together at another plurality of bond points corresponding to the canted teeth , as the web moves through the gap; and wherein the second ultrasonic horn and the second anvil are spaced apart from the first ultrasonic horn and the first anvil in the machine direction and downstream therefrom. a first ultrasonic horn ; and a first anvil spaced apart from the first ultrasonic horn by a gap so as to allow for translation of the web therethrough in a machine direction, wherein the first anvil includes an anvil insert comprising a pair of seal surfaces extending in a cross-machine direction that is orthogonal to the machine direction and being spaced apart in the machine direction so as to have a recess therebetween; wherein each of the pair of seal surfaces comprises canted teeth formed thereon, the canted teeth angled so as to provide both trailing edge and leading edge coverage in the cross-machine direction; wherein the first ultrasonic horn operates with the first anvil to ultrasonically bond the plurality of web layers together at a plurality of bond points corresponding to the canted teeth , as the web moves through the gap; a second ultrasonic horn ; and a second anvil spaced apart from the second ultrasonic horn by a gap so as to allow for translation of the web therethrough in the machine direction; wherein the second anvil includes another anvil insert comprising another pair of seal surfaces extending in the cross-machine direction and spaced apart in the machine direction so as to have a recess therebetween; wherein each of the pair of another pair of seal surfaces comprises canted teeth formed thereon angled so as to provide both trailing edge and leading edge coverage in the cross-machine direction; wherein the second ultrasonic horn operates with the second anvil to ultrasonically bond the plurality of web layers together at another plurality of bond points corresponding to the canted teeth , as the web moves through the gap; and wherein the second ultrasonic horn and the second anvil are spaced apart from the first ultrasonic horn and the first anvil in the machine direction and downstream therefrom. <EOS>
