Abstract
An apparatus for fabricating an elasticized material having at least one elastic strand transversely positioned across the apparatus. The apparatus includes a first bonding module and a second bonding module positionable in proximity to the first bonding module. At least one of the first bonding module and the second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis in a velocity vector direction, the face having a contour pattern containing a plurality of entrapment elements arranged along a width of the contour pattern, the plurality of entrapment elements having a land and a notch constructed to receive and hold the at least one elastic strand, wherein the contour pattern is arranged at an angle of between −30° and +30° from perpendicular to the at least one elastic strand with respect to the velocity vector direction, during bonding operation, and wherein the land and notch has a longitudinal axis that is at an angle of between −30° and +30° from parallel to the at least one elastic strand with respect to the velocity vector direction.
