Abstract: A method and device for conveying a ribbon of crimped material includes an air mover, a plenum connected to the air mover to receive air from the air mover, a series of directional slits and side walls. The directional slits air in fluid communication with the plenum so that air from the plenum exits through the directional slits in a predetermined direction. The directional slits are arranged in a generally planar configuration to form a conveyance track. The sides walls are provided on either side of the conveyance track to extend above the conveyance track. The crimped material may be a planar band of crimped fiber, such as a planar band of crimped acetate fiber. The crimps may extend in an up-and-down direction or in a back-and-forth direction. The plenum may be formed of a pair of elongated support pieces with cutout portions in the elongated support pieces.
