ABSTRACT:
A jet tube assembly for a jet tube sheet dryer comprises a jet tube which is generally rectangular in cross section and tapers from a large, air-delivery end to a small end. A rod is attached to the tube at the small end thereof in a manner such as not to block the small end of the tube and to project beyond the small end of the tube substantially in alignment with the longitudinal axis of the tube. A closure member is formed with an aperture so that it can fit over the rod and move relative thereto between a first position, in which the small end of the tube is substantially blocked, and a second position in which a substantial portion of the cross sectional area of the tube at its small end is unobstructed by the closure member.
