ABSTRACT:
A baffle structure that includes a generally cylindrical portion and at least one generally linear portion is associated with each roll in a yarn processing. The generally cylindrical portion is spaced a predetermined clearance distance from the surface of the roll with which it is associated to define a generally curved channel about the roll. The generally linear portion of each baffle structure extends toward the other roll, with the generally linear portions overlapping each other to define a substantially linear channel between adjacent upstream and the downstream rolls. The generally linear portion extending from the cylindrical portion of the upstream roll toward the downstream roll has an edge thereon. The edge is disposed within a predetermined close distance of the surface of the upstream roll such that the edge lies within the boundary layer of air able to be generated about the upstream roll. The generally curved channels and the substantially linear channel cooperating to define a pathway that substantially encloses the warp array of yarns as the same is moved over and between the rolls. In operation, a substantially uniform transverse temperature is maintained across the pathway at each point therealong, and at least a portion of the heated air about the upstream roll is stripped therefrom as yarn is conveyed from the upstream to the downstream roll.
