Abstract (en)

[origin: US4658512A] A predrying tower serves for heat-treating a vertically conducted length of material. In addition to infrared heating rods arranged on each side of the length of material and over the treatment height of the drying tower, respectively one air supply box is arranged bilaterally of the length of material. The air supply box extends over the height and width of the drying tower, with air slots oriented to direct air toward the length of material. In order to obtain a circulating air system, the air is exhausted above the treatment zone over the width of the length of material and conducted to a fan arranged at the end face of the drying tower, this fan blowing the treatment air downwardly in an air recycle chamber arranged likewise at the end face of the drying tower. An air ramming or air collecting chamber is arranged on the underside of the drying tower over the operating width, wherein the accelerated air is laterally introduced and exits upwardly via a heating device into the air conducting box.
