A method for making an elastomeric laminate, the method comprising steps of: rotating a pattern roll about an axis of rotation extending axially in a cross direction, the pattern roll comprising: first bonding elements extending outward from an outer circumferential surface of the pattern roll each comprising a bonding surface; discrete first channels in each bonding surface of a depth not entirely through the first bonding elements, wherein the discrete first channels are circumferentially spaced apart from each other and spaced apart from each other axially in the cross direction, and a protuberance extending axially in the cross direction between two of the discrete first channels; providing a pressing surface adjacent the pattern roll; providing an elastic strand, wherein the elastic strand defines a first cross sectional area in an unstretched state; stretching the elastic strand, wherein the stretched elastic strand defines a second cross sectional area that is less than the first cross sectional area; advancing a first substrate and a second substrate with the stretched elastic strand between the first substrate and the second substrate in a machine direction; partially wrapping the first substrate, the second substrate, and the stretched elastic strand on the pattern roll to cause the first substrate and the second substrate to press against each other and against the stretched elastic strand, wherein the stretched elastic strand extends through at least one discrete first channel; welding the first substrate and the second substrate together between a bonding surface and the pressing surface to create bonds between the first substrate and the second substrate, wherein the bonds are separated from each other in the cross direction by the stretched elastic strand positioned in the at least one discrete first channel to form a first sleeve surrounding the stretched elastic strand, wherein the first sleeve defines a third cross sectional area that is less than the first cross sectional area and equal to or greater than the second cross sectional area; compressing the first substrate, the second substrate, and the elastic strand between the pressing surface and the protuberance to sever the stretched elastic strand while the first substrate, the second substrate, and the elastic strand are partially wrapped on the pattern roll, wherein the severed elastic strand retracts and expands to create a frictional lock between the first sleeve and the severed elastic strand.
