A textile machine having circulating air heating by means of gas-heated heat exchangers, having flame or meander tubes arranged parallel to one another in a suction space, crosswise to the air stream of the latter, and burners switched ahead of them, is described. In order to be able to work with two burners in the case of high required heat output, and nevertheless to heat the air stream drawn in by the heat exchanger equally, in the case of indirect circulating air heating, everywhere in the stream cross-section, two burners, each having a subsequent tube heat exchanger, are each assigned to one half of the suction space, whereby the heating tubes of the two heat exchangers reach over the entire suction space width, in the main part of the suction space, crosswise to its air stream, but extend only over the suction space half assigned to the burner, in each instance, at least in a segment of the circulating air stream path in the suction space.
