Title
(ZH) 制备结构化表面的方法及由其得到的制品
Abstract
(ZH)

本发明公开了一种制备结构化表面的方法和一种机械紧固件前体。该方法包括为热塑性背衬(14、24、34、44)提供空间上隔开的直立柱(10、20、30、40),柱具有远端和附接到热塑性背衬的基座部分;使远端变形以在至少一些空间上隔开的直立柱上形成顶盖(12、22、32、42)从而得到带盖柱(18、28、38、48),其中至少一些顶盖(12、22、32、42)在形成时接触至少一个相邻顶盖;及分离带盖柱(18、28、38、48)。通常,所述至少一些顶盖在形成时至少部分地通过所述至少一个相邻顶盖成形。机械紧固件前体包括热塑性背衬和直立凸伸紧固元件,所述元件具有远端顶盖和附接到热塑性背衬的基座,且远端顶盖的面积大于基座的横截面积,凸伸紧固元件的基座相互间隔开,至少一些远端顶盖接触至少一个相邻远端顶盖。
