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 jets. These are parallel to the fabric, singly or in groups on one side across the width, in suitable brackets at the air circulation side. Typically, the fabric (1) is stretched across the width of the frame and held by grips or pins (2), which are fixed to a lengthwise traversing chain (4) on each side. The injectors (5) concentrate the airflow directly on to the fabric. The air is compressed (6) and fed into a channel (7) which may be flexible. The injectors are connected to this, giving the flow (8), which is reflected (9) upwards, into an enclosure (11). It is recirculated through a heat exchanger (12) into an interior box (10) and through bottom orifices (13) progressively, creating the ambient temperature. ADVANTAGE - The jets concentrate on the face or reverse of the cloth, only to the cloth width, to avoid waste of energy.
