    • A method of forming a touch fastener product having a sheet-form base and an array of discrete fastener elements each extending from the base includes providing a molded sheet-form base and an array of discrete fastener element preforms, each preform extending from the base and including both a stem portion rising from the base and a head portion both contiguous with a distal end of the stem portion and having an upper surface directed away from the base, the head portion including at least one laterally directed extension overhanging the base in a primary lateral direction between exposed sides of the fastener element preform and ending at a distal, free tip; and then forming respective caps, of a cap material of a higher flex modulus than the resin of the preforms, on the upper surfaces of at least some of the molded fastener element preforms to form the discrete fastener elements.
    • 形成具有片状基部和从基部延伸的离散紧固件元件阵列的接触紧固件产品的方法包括提供模制片状基部和离散紧固件元件预成型件阵列 ,每个预成型件从基部延伸并包括从基部上升的杆部和均与杆部的远端邻接的头部,并且具有远离基部的上表面,头部包括至少一个侧向 所述定向延伸部在所述紧固件元件预成型件的暴露侧之间在主要横向方向上悬于所述基部并且在远侧自由尖端处终止; 然后在至少一些模制的紧固件元件预成型件的上表面上形成相对于预成型件的树脂具有更高挠曲模量的帽材料的相应帽,以形成离散的紧固件元件。
