Method and apparatus for use in manufacturing a filter element

摘要

A method of manufacturing a porous fluid treatment element, e.g. a filter element, includes forming a layered structure having at least two layers and subjecting the layered structure to at least a heat treatment. The step of forming a layered structure includes forming a first layer including particulate matter including at least a binder and applying a second layer including particulate matter including at least a binder directly onto the first layer on a first side thereof. The step of forming a layered structure further includes applying at least one of radiation and heat to at least the first side of the first layer prior to applying the second layer.

1. A method of manufacturing a porous fluid treatment element, comprising the steps of:
forming a layered structure having at least two layers, the step of forming a layered structure including: forming a first layer comprising particulate matter comprising at least a binder that binds other particles when subjected to heat or radiation of another form than heat; and applying a second layer comprising particulate matter comprising at least a binder directly onto the first layer on a first side thereof, the binder binding the other particles when subjected to the heat or the radiation of another form than heat; and subjecting the layered structure to at least a heat treatment, wherein the step of forming the layered structure further includes applying at least one of radiation and heat to at least the first side of the first layer prior to applying the second layer.
