    • An elongate fastener assembly (l0) comprising an elongate flexible polymeric backing strip (l2) from which project a multiplicity of headed stems (l8) adapted to engage loops on materials pressed against the heads (20), and an open porous permanent attachment layer (22) attached to the surface of the backing strip (l2) opposite the stems (l8) which has sufficient open area to receive foam to permanently attach the fastener assembly (l0) to a foamed article. The fastener assembly (l0) has a temporary attachment layer (24) comprising granular ferromagnetic material along both sides of the backing strip (l2), which temporary attachment layer (24) is adapted to be attracted by magnets to temporarily hold the fastener assembly (l0) in position during a foaming process and restrict the foam from contacting the headed stems (l8).
    • 细长的紧固件组件(10)包括细长的柔性聚合物背衬条(12),所述长形的柔性聚合物背衬条(12)从所述细长的柔性聚合物背衬条(12)突出,多个带头的茎(18)适于接合压在头部(20)上的材料上的环,以及开放的多孔永久附着层 22),其连接到与具有足够开口面积的杆(18)相对的背衬条(12)的表面上,以接收泡沫以将紧固件组件(10)永久地附接到泡沫制品上。 紧固件组件(10)具有临时附接层(24),该临时附接层(24)包括沿着背衬条带(12)的两侧的颗粒状铁磁材料,该临时附着层(24)适于被磁体吸引以暂时保持紧固件组件 10)在发泡过程中处于适当位置,并限制泡沫与头部杆(18)接触。
