In a method and apparatus for securing engagement between fastening components of a pre-fastened garment the fastening components are aligned in at least partially overlapping relationship with each other and engaged with each other to define an engagement seam. The fastening components are then flexed at the engagement seam to generate a shear stress at the seam to thereby promote increased engagement between the fastening components. In another embodiment, the fastening components are delivered in a predetermined direction to a nip and then drawn into the nip at a speed greater than the speed at which the fastening components are delivered to the nip. The fastening components are passed through the nip generally to squeeze the fastening components together at the engagement seam for promoting enhanced engagement between the fastening components.
