A filter element comprises one or more several tubular filter media element segments, which may be pleated filter media ring segments. One or more heat activated disks are used to connect each tubular filter media element segments together and/or to connect tubular filter media element segments with one or more end cap supports. The heat activated disks are solid in form for assembly with tubular filter media ring segment and then heat activated to bond with tubular filter media ring segments. Multiple end caps can be simultaneously bonded to one or more tubular filter media element segments if a filter stack assembly of component are heated together, such as in an oven. Filter media may also be simultaneously cured. Heat activated disks may be used as pleat stabilizers and/or for and/or as part of end caps.

Heat activated adhesive for filters that may contain multiple elements

The disclosure is directed toward presses which may comprise planar or curved press plates that can be driven toward and away from each other such as via linear reciprocating movement to press filter media sheets as opposed to using rolls. The press plates can create such features as embossments that may have the ridges and grooves, brands, creases or other such features. The press can create pleated packs or individual panels for non-pleated packs. Additionally, a variety of embossed pleat packs, unique shapes, structural components and other pleat packs that may be formed by presses or other methodology are disclosed as well as filter cartridges using such pleat packs.

Filter media packs, methods of making and filter media presses

The present disclosure is directed toward assembly of pleat packs using a welder and an anvil that can push adjacent pleat panels together along a crease. Other aspects are directed to welding pocket pleats and welded pocket pleats formed thereby that are suitable for filter fluid and ultrasonically cutting and sealing seams into filter media using a welding assembly such as an ultrasonic sonotrode and an anvil.
