Abstract: Provided are methods and apparatus for transporting either an entire web or discrete components of disposable products. The invention is a means of conveying the web or diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this. Methods and apparatus are disclosed to provide sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

Abstract: An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a bonding unit configured to bond a first web layer to a second web layer via a bond pattern that includes at least one bond line having at least one pair of adjacent bonds. The bonding unit secures an elastic thread within a passage defined by the at least one pair of adjacent bonds. The passage has a cross-sectional area smaller than a cross-sectional area of the elastic thread in a non-tensioned state.

Abstract: 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.

Abstract: 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.
