ABSTRACT:
A tube for an impinging jet air drier for wood veneer has a circular cross-section throughout 270 degrees of its circumference, the remaining 90 degrees comprising two planar portions, one disposed perpendicularly to the direction of travel of a sheet of material through the drier, the other generally facing the sheet of material but forming an obtuse angle with the first portion at a line of juncture disposed in the downstream direction of sheet travel. A plurality of round holes are punched in the planar portion facing the sheet of material. The holes are disposed in rows parallel to the longitudinal axis of the tube. The shape of the tube serves as a guide for the sheet material while discharging air thereacross. The configuration permits the upper tube in each pair to be disposed about 5/8 inch above the plane of travel of the sheet material and the lower tube to be disposed about 3/8 inch therebelow.
