    • An apparatus (10) for making an elastic laminate including a crosslinked elastic layer (14) formed of an elastic copolymer includes a die (12) for extruding a layer of crosslinkable elastic copolymer, at least one roll (16) for conveying the elastic layer, a supply source (18) for providing at least one nonwoven(20) web, a lamination nip (22) for laminating at least one nonwoven web to the elastic layer, a processing unit (26) for crosslinking the elastic layer and a winder for collecting the elastic laminate. The crosslinkable elastic copolymer may be a crosslinkable elastic styrenic block copolymer, a crosslinkable semi-crystalline polyolefin plastomer, or a crosslinkable propylene-ethylene copolymer. The crosslinkable elastic layer may be extruded in the form of a plurality of parallel filaments such as by a filament die. The processing unit may be positioned between the at least one roll and the lamination nip or may be positioned between the lamination nip and the winder. The processing unit may have an open or a closed configuration and may be an electron beam processing unit.
    • 一种用于制造包括由弹性共聚物形成的交联弹性层(14)的弹性层压材料的装置(10)包括用于挤出可交联弹性共聚物层的模具(12),用于输送弹性层的至少一个辊(16) ,用于提供至少一个无纺布(20)的供应源(18),用于将至少一个非织造纤维网层压到所述弹性层的层压辊隙(22),用于使所述弹性层交联的处理单元(26) 用于收集弹性层压板。 可交联弹性共聚物可以是交联性弹性苯乙烯嵌段共聚物,交联性半结晶聚烯烃塑性体,或交联性丙烯 - 乙烯共聚物。 可交联弹性层可以以多个平行长丝的形式挤出,例如通过丝模。 处理单元可以位于至少一个辊和层压辊隙之间​​,或者可以位于层压辊隙和卷绕机之间。 处理单元可以具有打开或闭合配置,并且可以是电子束处理单元。
