The apparatus also includes an air distribution tube positioned within the through air roll. The air distribution tube has a cylindrical surface, a first end, and a second end, and the cylindrical surface of the air distribution tube has a plurality of openings configured for the flow of air there through. The apparatus further includes a first adjustable deckle associated with the air distribution tube configured to alter the flow of air through the air distribution tube. The first adjustable deckle includes a first floating plate configured to selectively cover a first portion of the plurality of openings in the air distribution tube, and a first deckle wall, wherein the first deckle wall is movable independent of the first floating plate. A method of assembling a through-air apparatus for drying or bonding paper or non-woven products is also provided.

Through-air apparatus with adjustable deckle

A through-air apparatus for drying or bonding paper or non-woven products is provided. The apparatus includes a through air roll, a first tension plate configured to hold a wire sleeve which is configured to extend around the roll, the first tension plate including at least one tension arc segment. The apparatus also includes a first cam mechanism associated with the at least one tension arc segment, wherein the first cam mechanism is configured to move the tension arc segment to adjust the position of the tension arc segment relative to the outer circumference of the first end of the roll, so that as the roll and first tension plate rotate about the first axis, the first tension plate is concentric with the roll.
