1. A bonding apparatus comprising:
a rotary anvil comprising:
a plurality of anchoring projections positioned in an anchoring region of the rotary anvil and constructed such that adjacent anchoring projections fuse a pair of facing web layers together with pairs of adjacent anchoring bonds that anchor an elastic thread passing between the adjacent anchoring bonds in position relative to the pair of facing web layers, the plurality of anchoring projections arranged in a plurality of anchoring weld lines spaced apart along a circumferential axis of a face of the rotary anvil; and
a break bar that extends outward from the face of the rotary anvil in a deactivating region of the rotary anvil and is constructed to sever the elastic thread, the break bar having a length in a circumferential direction that spans at least two of the plurality of anchoring weld lines.
