    • A method for making a zoned apertured nonwoven web comprises providing an unapertured nonwoven web having a first plurality of weakened locations in a first pattern in a first zone and a second plurality of weakened locations in a second pattern in a second zone. The method comprises applying a substantially cross machine directional tensioning force to the nonwoven web to cause the nonwoven web to rupture at some of the first and second pluralities of weakened locations. The applying step creates a plurality of first apertures in the nonwoven web coincident with the some of the first plurality of weakened locations and a plurality of second apertures in the nonwoven web coincident with the some of the second plurality of weakened locations. The cross machine directional width of the nonwoven web after the applying step is substantially the same in the first zone and the second zone.
    • 一种用于制造分区的有孔非织造纤维网的方法包括提供在第一区域中具有第一图案中的第一多个弱化位置和在第二区域中具有第二图案的第二多个弱化位置的未孔的非织造纤维网。 所述方法包括向所述非织造纤维网施加基本上交叉的机器定向张紧力,以使得所述非织造纤维网在所述第一和第二多个弱化位置中的一些处破裂。 所述施加步骤在所述非织造织物中产生与所述第一多个弱化位置中的所述一些重合的多个第一孔,并且所述非织造织物中的多个第二孔与所述第二多个弱化位置中的一些相重合。 在施加步骤之后的非织造纤维网的横向机器方向宽度在第一区域和第二区域中基本相同。

    • A machine for treating a fabric (T) with air, comprises a tunnel (10) for pneumatically transporting the fabric and means for injecting the air into the tunnel above and/or below the fabric and comprising at least one diverting valve (16;18) located substantially half way along the tunnel and having two channels (16a,16b;18a,18b) which are oriented to direct the air flow entering the tunnel in one direction or the other. The valve comprises an adjustable baffle (17;19) adapted to shut off access to the channels (16a,16b;18a,18b) either wholly or partly. In the treatment method of the invention, the air flow (F;F′) entering the tunnel is divided into two unequal components (F1, F2; F1′, F2′) directed towards opposite ends of the tunnel.
    • 一种用于与空气处理织物(T)机,包括隧道(10),用于空气输送的织物和用于将空气注入到隧道上方和/或该织物下方并且包括至少一个分流阀(16; 18 )基本上位于中途沿隧道,并且具有两个通道(16A,16B; 18A,18B),它们定向成在一个方向或另一个方向进入隧道的空气流。 该阀包括在可调挡板(17; 19),其适于切断访问信道(16A,16B; 18A,18B)全部或部分。 在本发明的治疗方法中,空气流(F; F“)进入隧道被分成两个不相等的组分(F1,F2,F1”,F2“)朝向所述隧道的相对端。
