    • A forming device for gathering the width of a traveling web is disclosed. The forming device includes opposing arrays of flute-forming bars that can be interlaced to define therebetween a longitudinal flute-forming labyrinth effective to reduce the width of a web traveling therethrough by a preselected take-up ratio. The flute-forming bars are curved beginning at an entry end of the forming device such that they converge in a lateral direction as they proceed in the machine direction. In this manner, individual elements of the web traveling between the respective arrays in the machine direction follow contour lines along the curved bars or between adjacent ones of the curved bars so that no such element crosses any flute-forming bar in the cross-machine direction as the web travels and is fluted. A corrugating die for introducing a near-net shape to the intermediate-fluted web is also disclosed, as are a corrugating line incorporating these operations and methods for its operation.

    • A forming assembly comprises two presser members (22,24) each having a corrugated surface for receiving a workpiece made up of generally diamond-shaped pockets (10). Each presser member is made up of sections (22 a ,22 b ; 24 a , 24 b ) mounted on slide rods (38) for movement between a spaced-apart position, in which a workpiece can be located therebetween, and a closed position, movement into which, while the workpiece is held between the presser members, is effective to compress the workpiece laterally. For holding the pockets in their diamond shape formers (20) are inserted therein. A flange (18) is formed at one end of the workpiece and integral therewith by pressing outwardly folded material against a lateral end face of the presser members (22,24) using a presser plate (52). This forming method is especially suitable for forming self-supporting filter units.
    • 成形组件包括两个压紧构件(22,24),每个压件构件具有波纹表面,用于容纳由大致菱形的凹穴(10)构成的工件。 每个按压构件由安装在滑杆(38)上的部分(22a,22b; 24a,24b)组成,用于在工件位于其间的间隔位置和关闭位置之间移动, 当工件保持在压紧构件之间时,有效地横向压缩工件。 为了将其中的凹坑保持在其钻石形状体(20)中。 在工件的一端处形成凸缘(18),并通过使用压板(52)将向外折叠的材料压靠压紧构件(22,24)的侧端面而与其成一体。 该成形方法特别适用于形成自支撑过滤器单元。
