    • Touch fasteners with different portions having different material properties, and methods and apparatus for making such a product. In one embodiment, the fastener includes a cross-linkable polymer, and a first portion of the fastener is cross-linked and a second portion of the fastener is not cross-linked or is cross-linked to a degree less than said first portion. In another embodiment, the fastener is made in a continuous process on a rotating mold roll having a plurality of fastener element mold cavities extending into the mold roll from its outer circumferential surface. The method includes applying a first polymer to the mold roll and forcing some of the first polymer into the mold cavities, with some of the first polymer remaining on the surface of the mold roll in the form of a film having thickness; with a doctoring blade, removing at least some of the first polymer remaining on the surface of the mold roll to at least reduce the thickness of the film of the first polymer on the mold roll surface (in some cases, substantially all of the polymer on the mold roll surface is removed); and applying a second polymer to the mold roll, the second polymer being compatible with, and adhering to, the first polymer.
    • 接触具有不同材料性质的不同部分的紧固件,以及用于制造这种产品的方法和装置。 在一个实施例中,紧固件包括可交联的聚合物,并且紧固件的第一部分是交联的,并且紧固件的第二部分不是交联的或者交联到小于所述第一部分的程度。 在另一个实施例中,紧固件以连续的方式制造在具有从其外圆周表面延伸到模具辊中的多个紧固件元件模腔的旋转模具辊上。 该方法包括将第一聚合物施加到模具辊上并迫使一些第一聚合物进入模腔,其中一些第一聚合物保留在具有厚度的膜形式的模具辊的表面上; 使用刮刀,除去保留在模具辊表面上的至少一些第一聚合物以至少减小模具辊表面上的第一聚合物膜的厚度(在一些情况下,基本上所有的聚合物都在 去除模具辊表面); 以及将第二聚合物施加到所述模具辊上,所述第二聚合物与所述第一聚合物相容并附着于所述第一聚合物。
