Abstract:
A process for automatedly manufacturing unit fluid filters, each unit including a frame defining opening with filter medium extending thereacross comprising: continuously feeding at least one preselectively sized first layer of filter medium from a supply zone to a correspondingly sized unit flow-through frame supply zone, said frame supply zone including stacked unit frames with each unit frame defining a flow-through opening, said frame supply zone further including cooperative unit frame holding and alignment means, said stacked unit frames and said holding and alignment means serving to selectively hold, align and position each unit frame into cooperatively assembled relation with said continuously fed layer of filter medium so that said layer of filter medium extends across said flow-through opening of each of said spaced flow-through frames, continuously feeding said aligned and assembled flow-through unit frames and filter medium layer to a sealing zone to seal said filter medium to the periphery of each of said assembled unit flow-through frames; and, separating each of said assembled filter medium sealed flow-through frames from said continuous process.
