Abstract
A filter in a printing machine traps contaminants from a stream of air passing therethrough. The filter includes a support member defining an aperture therethrough for the passage of the stream of air. The support member has a cross section in a plane perpendicular to the flow of the stream of air. The cross section has an oblong shape and includes a longitudinal axis and a transverse axis. The filter further includes an air permeable member supported by the support member. The air permeable member defines a opening therein for receiving the stream of air. The filter further includes a reinforcement connected to the air permeable member. The reinforcement extends along the air permeable member in the direction of the stream of air. The reinforcement is positioned with respect to the support member so as to shape the air permeable member so that the opening may be sufficiently large to efficiently receive the stream of air.
