A machine and method for manufacturing an elastic composite structure for disposable sanitary products involves manufacturing the elastic composite structure with an elasticized leg and leg cuff region in a manner that minimizes or eliminates the use of consumable adhesives. The elastic composite structure includes pairs of leg bonds and cuff bonds that are formed without adhesive and anchor respective leg and cuff elastic threads in position relative to facing web layers. The leg bonds and cuff bonds are formed using one or more anvils that include discrete raised projections.

An elastic composite structure includes a plurality of tensioned elastic threads positioned between first and second web layers. A pattern of laminating bonds fuse the first and second web layers together within a deactivated zone of the elastic composite structure. A cut end of a first portion of a tensioned elastic thread and a cut end of a second portion of the tensioned elastic thread are positioned on opposing ends of the deactivated zone. A pattern of anchoring bonds fuses the first and second web layers together within an anchored zone bounding opposing ends of the deactivated zone. The anchored zone includes a first plurality of bonds that anchor the first portion of the tensioned elastic thread to the first and second web layers and a second plurality of bonds arranged that anchor the second portion of the tensioned elastic thread to the first and second web layers.

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a rotary anvil comprising a face surface, a plurality of non-linear ridges defined by a first plurality of grooves in the face surface, and a plurality of projections in each of the plurality of non-linear ridges. Each projection of the plurality of projections comprises a contact surface having parallel facing surfaces and parallel end surfaces.

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes at least one structure that guides web layers in a machine direction, an elastic thread combiner that combines a plurality of elastic threads to form a combined elastic thread assembly, and a bonding unit. The bonding unit bonds the web layers together via a bond pattern that includes bond lines that each have at least one pair of adjacent bonds, which anchor the combined elastic thread assembly within a passage defined by a pair of adjacent bonds in each of the plurality of bond lines. The passage is narrower than the combined elastic thread assembly in a non-tensioned state and wider than one of the plurality of elastic threads in a non-tensioned state.

An apparatus for manufacturing an elastic composite structure for an absorbent sanitary product includes an anvil with weld pattern comprising at least one anchoring region and at least one deactivating region. The anchoring region includes anchoring welds that form anchoring bonds that fuse facing web layers and anchor elastic thread(s) in position relative to the facing web layers. The deactivating region includes a break bar constructed to sever the thread(s). A method of manufacturing the elastic composite structure includes positioning a tensioned elastic thread between web layers, fusing the web layers to form an anchored zone that includes anchoring bonds that fuse the web layers and anchor the tensioned elastic thread therebetween, and cutting the thread to form a deactivated zone between adjacent portions of the anchored zone that is free of tensioned threads. The method further includes fusing the web layers within the deactivated zone.
