    • A touch fastener strip includes a pair of longitudinal barrier walls each extending upward from a base, a plurality of lateral barrier walls each extending upward from the base and between facing surfaces of the barrier walls, thereby defining one or more fastening cells, and a pair of wave walls each extending upward from the base and outboard the barrier walls thereby defining a relief space. Each wave wall has a wave shape having rising and falling edges, at least one of the edges having a slope in the range of 3° to 65°. In some cases, the wave shape has a duty cycle of 40% to 60%, and may include a sine wave, a triangle wave, a ramp wave, and/or a bi-modal wave having two different peak points in a given cycle of the shape. In one example application, the strip may be anchored in a foam cushion product.
    • 接触紧固带包括一对纵向阻挡壁,每个纵向阻挡壁从基部向上延伸,多个横向阻挡壁各自从基部向上延伸并且在阻挡壁的相对表面之间延伸,从而限定一个或多个紧固单元和一对 的波壁,每个壁从基部向上延伸并且在阻挡壁外侧,从而限定浮雕空间。 每个波浪壁具有具有上升和下降边缘的波形,至少一个边缘具有在3°至65°范围内的斜率。 在一些情况下,波形具有40%至60%的占空比,并且可以包括在给定周期中具有两个不同峰值点的正弦波,三角波,斜波和/或双模波 的形状。 在一个示例性应用中,条带可以锚定在泡沫垫产品中。

    • A male touch fastener strip includes an elongated base having a thickness and defining a longitudinal direction and a lateral direction perpendicular to the longitudinal direction across the base between longitudinal edges of the base, and a field of male fastener elements each having a stem extending from a broad face of the base and a head at an upper end of the stem and overhanging the base for engaging fibers. The fastener element stems and broad face of the base together form a unitary mass of resin. The male touch fastener strip also includes longitudinal barrier walls rising from the broad face of the base on either side of the field of male fastener elements, and a pair of segmented walls rising from the broad face of the base, each segmented wall of the pair disposed laterally outboard of a respective nearest one of the longitudinal barrier walls and including a series of wall segments defining longitudinal gaps therebetween. Each segmented wall and its nearest longitudinal barrier wall define therebetween a foam relief space for receiving a foam material. Each segmented wall defines a flow gap for allowing the foam material to enter the foam relief space.
    • 男性接触紧固带包括细长基部,其具有厚度并且限定纵向方向和垂直于穿过基部的纵向边缘之间的基部的纵向方向的横向方向,以及阳性紧固件元件的领域,每个阳离子元件具有从 基部的宽面和在杆的上端处的头部并且伸出用于接合纤维的基部。 紧固元件杆和基部的宽面一起形成整体的树脂。 男性接合紧固件条还包括纵向阻挡壁,其从基部的宽面上突出,位于雄性紧固件元件的场的任一侧,以及一对分段壁,其从基部的宽面上升,每对分隔壁 横向排列在相应最近的一个纵向阻挡壁的外侧,并且包括限定其间的纵向间隙的一系列壁段。 每个分段壁和其最近的纵向阻挡壁在其间限定了用于接收泡沫材料的泡沫释放空间。 每个分段壁限定用于允许泡沫材料进入泡沫浮雕空间的流动间隙。
