    • An apparatus (10) for manufacturing a filter element includes a first mould element (12) having a plurality of spaced parallel rib (14) defined thereon. A second mould element (18) is arranged in spaced alignment relative to the first mould element (12), the second mould element (18) carrying a plurality of spaced parallel ribs (22) displaceably thereon. A displacement means (24) which includes a cam arrangement (28) is mounted on the second mould element (18) for displacing the ribs (22) of the second mould element (18) sequentially towards the first mould element (12) such that, in use, when the ribs (22) of the second mould element (18) are displaced into meshing engagement with the ribs (14) of the first mould element (12), pleats or folds are formed in a sequential fashion in a batt of filter material arranged between the mould elements (12,18). The cam arrangement (28) comprises a plurality of cam members (32), a cam member (32) being associated with each rib (22) of the second mould element (18) and the cam members (32) having consecutively greater dwell angles to facilitate the sequential formation of the pleats or folds in the batt.
    • 用于制造过滤元件的设备(10)包括:第一模具元件(12),其具有限定在其上的多个间隔开的平行肋(14)。 第二模具元件(18)相对于第一模具元件(12)以间隔对齐的方式布置,第二模具元件(18)在其上可移动地承载多个间隔开的平行肋(22)。 包括凸轮装置(28)的位移装置(24)安装在第二模具元件(18)上,用于使第二模具元件(18)的肋(22)顺序地朝向第一模具元件(12)移动,使得 在使用中,当第二模具元件(18)的肋条(22)移位成与第一模具元件(12)的肋条(14)啮合时,褶皱或褶皱按顺序形成在絮垫 的过滤材料布置在模具元件(12,18)之间。 凸轮装置(28)包括多个凸轮构件(32),与第二模具元件(18)的每个肋(22)相关联的凸轮构件(32)和具有连续更大驻留角度的凸轮构件(32) 以便于在絮垫中顺序地形成褶皱或褶皱。
