ABSTRACT:
Process and apparatus for the continuous, tensionless treatment of textile material lengths and similar web-shaped flat materials wherein the material is conveyed in gathered form to at least one treatment zone of a material treating unit. A fluid stream impinges intermittently from below upon the length of material approximately at right angles to the conveying direction thereby straightening and compressing the material by an alternating lifting and falling of the material. An air permeable conveyor belt may be employed to convey the length of material through the treating units or a number of spaced individual rollers may be provided in the treating unit with the material forming a loop between adjacent rollers which loop is acted upon by the stream of fluid. A sensor arrangement is provided for determining and controlling the length of the loop so as to maintain such length within predetermined limits. The air stream is directed against the material by way of at least one nozzle associated with one or more treatment zones in the treatment unit. The nozzle may be pivotally mounted so as to cooperate with adjacent treating zones or closing elements may be provided for closing one or more nozzles thereby intermittently affecting the respective treatment zones.
