A transversely extensible continuous elastic laminates includes a continuous elastic tape sandwiched between two continuous webs, and at least one row of tabs extending transversely outside the two webs, wherein the tabs are made of a non-woven material and have respective micro-hook formations integrally formed in the non-woven material forming the tabs.

A surface fastener includes a base part and a plurality of engaging elements formed integrally with the base part. A lower half part of the stem portion has a first shape in which an outer surface is formed straightly or substantially straightly on viewing the engagement element from the machining direction, and the lower half part has a second shape including a part where an outer surface is curved toward the surface of the base part on viewing engagement element from the cross direction. Thus, the surface fastener has a structure and/or characteristic that is different between the machining direction and the cross direction.

A touch fastener element has a stem rising from a resin sheet, and a head disposed at an upper end of the stem and spaced from the resin sheet. The head has two arms that extend in opposite directions to distal ends, the arms having respective lower surfaces that overhang the resin sheet. The fastener element has two opposite side surfaces that form contiguous surfaces of the stem and both arms. The lower surface of each arm defines at least one recess extending away from the resin sheet and disposed between lower arm surface portions that face the resin sheet, such that the recess of each arm is spaced from both the stem and the distal end of the arm.

A method of creating projections in a substrate is presented. A first device is provided with an outer surface defining recesses, where each recess has a first portion proximate the outer surface with a first perimeter and first depth and a second portion distal the outer surface with a second perimeter and second depth. The first perimeter is larger than the second perimeter and the first depth is less than the second depth. The first portion of the recesses substantially surrounds the second portion of the recesses. The method also includes forming a nip between a source of vibration energy and the outer surface and conveying the substrate through the nip to create precursor projections. The method also includes heating portions of the precursor projections and applying pressure to the heated portions to flatten the portions and increase a perimeter of the portions to form the projections.

A device including a support, having a lower face and an upper face, the support forming a strip extending along a longitudinal direction, a base extending along the longitudinal direction between a first end and a second end, the base having a lower face facing the upper face of the support, and an upper face, the base having a constant thickness between its lower face and its upper face, a plurality of retaining elements extending from the upper face of the base, wherein the base is secured to the support in a non-uniform manner, and includes at least one segment secured to the support, and at least one portion not secured to the support.
