Claim 13:
14. A fiber treatment plant comprising:
a web-forming device for a moving material web configured as a fibrous web;
a laying device for the fibrous web;
a liquid jet hydroentanglement device; and
a drying device comprising:
a drying chamber with a ventilating device, an inlet, an outlet and a fluid-permeable conveying device for the moving material web, wherein the material web is transported within the drying chamber with the conveying device and is dried with a flow of a heated gas generated by the ventilating device; and
a suction device configured to generate an additional flow comprising a suction flow and to suction off locally and remove liquid contained in the material web at one or more suction point(s) at the material web, wherein the ventilating device generates a circulating flow of a heated gas, which is directed transversely through the material web and through the conveying device, wherein the suction device comprises a suction element and a vacuum generator connected to the suction element for generating the suction flow, the suction element being arranged at the at least one of the one or more suction points at the material web and at the conveying device, wherein the suction device suctions the heated gas, from the drying chamber at the respective suction point at the material web, wherein the suction flow and at least a portion of the circulating flow of the heated gas are present next to one another at the respective suction point at the material web and are directed in the same direction.
