2. The dryer according to claim 1 , further comprising at least one of means for distributing the fresh air, means for separating the exhaust air from the fresh air and means for dividing the additional compartment into segments, arranged inside the additional compartment.

3. The dryer according to claim 2 , wherein the at least one means comprise separating plates or guide plates.

4. The dryer according to claim 1 , wherein ends of the drums have end face openings and the drying air is discharged into the additional compartment via the end-face openings of the drums.

5. The dryer according to claim 1 , further comprising fans for extracting the exhaust air from the dryer chamber arranged at the heating and fan chamber.

6. The dryer according to claim 5 , wherein the heating and fan chamber is connected to the additional chamber via connections.

7. The dryer according to claim 1 , wherein the heating and fan chamber is connected to the dryer chamber via air channels.

8. The dryer according to claim 1 , further comprising a heat exchanger arranged outside the additional compartment that uses the exhaust air withdrawn from the drying air to heat the fresh air.

9. The dryer according to claim 1 , further comprising means for heating the drying air arranged inside the heating and fan chamber.

10. The dryer according to claim 9 , wherein the means for heating the drying air comprises one of a heat exchanger, a gas burner, or an electric heater.

11. A method of drying a textile fabric web, comprising:

heating and conducting drying air into a dryer chamber in which a fabric web is wrapped around at least part of at least two drums arranged inside the dryer chamber and each drum having an open end;

supplying fresh air via a single channel to a separate and additional compartment that extends across the open ends of the drums in the dryer chamber;

mixing the fresh air with the drying air inside the separate and additional compartment, after the drying air passes through the fabric web; and

flowing the heated drying air mixed with the fresh air through the fabric web and discharging exhaust air first via an interior chamber of the drum, and then via a single channel from the separate and additional compartment.

12. The method of drying a textile fabric web according to claim 11 , wherein the supplying step includes supplying the fresh air to the separate and additional compartment in a region of an outlet of the fabric web and the discharging step includes discharging the exhaust air from the additional compartment in a region of an inlet of the fabric web.

13. The method of drying a textile fabric web according to claim 11 , further comprising withdrawing a mass sub-flow of exhaust air from the drying air and supplying a mass sub-flow of fresh air to the drying air.

14. The method of drying a textile fabric web according to claim 13 , including removing the exhaust air from the drying air at a location at which the drying air has its lowest temperature level or energy level.

15. The method of drying a textile fabric web according to claim 11 , further comprising heating the fresh air and the drying air inside the heating and fan chamber.

16. The method of drying a textile fabric web according to claim 15 , wherein the heating of the fresh air and the drying air is effected by one of a heat exchanger, a gas burner, or an electric heater.

17. The method of drying a textile fabric web according to claim 11 , including heating the fresh air before flowing into the separate and additional compartment.
