    • A method of making a structured surface and a mechanical fastener precursor are disclosed. The method includes providing a thermoplastic backing with spaced-apart, upstanding posts with base portions attached to the thermoplastic backing and distal tips; deforming the distal tips to form caps on at least some of the spaced-apart, upstanding posts to provide capped posts, wherein at least some caps upon forming touch at least one adjacent cap; and separating the capped posts. Typically, the at least some caps upon forming are shaped at least partially by the at least one adjacent cap. The mechanical fastener precursor includes a thermoplastic backing and upstanding male fastening elements with bases attached to the thermoplastic backing and distal caps larger in area than the cross-sectional area of the bases, wherein the bases of the male fastening elements are spaced apart, wherein at least some of the distal caps touch at least one adjacent distal cap.
    • 公开了一种制造结构化表面和机械紧固件前体的方法。 该方法包括提供具有间隔开的直立柱的热塑性背衬,底部附接到热塑性背衬和远端尖端; 使远端尖端变形以在至少一些间隔开的直立柱上形成盖,以提供封盖柱,其中至少一些盖在成形时接触至少一个相邻盖; 并分隔封盖柱。 通常,形成时的至少一些盖至少部分地由至少一个相邻的盖成形。 机械紧固件前体包括热塑性背衬和直立的阳紧固元件,其具有附接到热塑性背衬的基部和远离顶盖的面积大于基部的横截面面积,其中阳紧固元件的基部间隔开,其中在 至少一些远端帽接触至少一个相邻的远端帽。
