The stenter machine is the most expensive and important fabric drying and finishing machine. It stretches fabric widthwise and regulates the uniform width using endless chains carrying pins or clips. Hot air is directed from above and below through multiple chambers to dry and heat set the fabric. Stenter machines control various parameters like chamber temperature, moisture retention, stretch/shrinkage, fabric width and weight. They are used to dry, heat set, apply finishes and coatings to woven and knitted fabrics.
