Abstract: An apparatus for heatsetting a knitted fabric in tubular form comprises flat expansion means which extend the tubular fabric in substantially flattened form, with two superimposed surfaces, and cause said fabric to assume a preselected width, conveying means which feed said flattened tubular fabric, heatsetting elements which form at least one air flow, at a preselected temperature, and guiding rods associated with the conveying elements and the heatsetting elements; the rods being capable of supporting internally the flattened tubular fabric along its side edges, owing to the action of the heatsetting elements, while keeping the side edges extended, leaving the two superimposed surfaces free to be passed through by the air flow and keeping the width of the flattened tubular fabric unchanged.
