On a stenter frame the fast moving stretched textile fabric is subjected to a force of warm air. This may be directed from one or both sides, through orifices, and the air pressure is increased by means of an air injector jet. Typically, the fabric (1) in the roll is held across the width by grips, or a pinned plate (2) attached to the chain drive (3), which conveys the fabric along the frame. The box surrounding the fabric at the top (4) and bottom (6) has numerous orifices (5). This is part of the air circulation system, which is developed by the injector jet (7), forcing air along the passages (9,10). A flap (11) can direct the pressure into the area of most requirement. In this manner the air is forced through the fabric in direction (12) or reflected from the fabric in direction (13,14) and this current is circulated through the heat exchanger (15). A suction is developed between the heat exchanger and the injector (7). These may be incorporated in both the top and bottom box, with separate air intake and exhaust. ADVANTAGE - The ventilator system is replaced in a reduced space by a high performance drying equipment, based on the air injectors.
