摘要：
A method of manufacturing a filter (10) comprises the steps of assembling multiple layers of filtration material (40) on top of one another to form an assembly; holding the assembly between an ultrasonic weld horn (70) and a weld nest (60) so that the assembly has a marginal area outside of an edge formed on either the nest (60) or the weld horn (70); and operating the weld horn (70) so as to cause the marginal area to be cut off from the assembly at the edge and to simultaneously seal together the layers of filtration material (40) of the remaining assembly at the edge. A filter (10) made by the process and an apparatus used to practice the process are also disclosed.
