Abstract: A dryer of the tenter type has at least one air circulating unit consisting of a series of blowers drawing air from the drying chamber through a heater common to the series. The fans of the blower deliver reheated air back into the drying chamber in a manner such that each fan delivers air between a different pair of courses of the fabric travelling through the drying chamber. The blower which delivers drying air to the courses which include the exiting course is operable to deliver air thereto at a temperature lower than that established by the heater, a result attained by bypassing withdrawn air about the heater, by utilizing ambient air entering the dryer to make up for that lost by vapor withdrawal, or by combinations of bypassed and such make up air.
