Summary:Process for the uniform pre-drying of damp textile material webs, subsequent to a continuous wet treatment operation, including measuring the moisture content remaining on the textile material, wherein, in the course of the material run, immediately behind an infrared pre-drying tunnel for the continuously fed material, several measuring positions are arranged transversely to the transport direction of the material, and measurements of the residual moisture are made by means of a contactless method, determining measuring pulses in this manner and transmitting these to the control elements of the preceding pre-dryer and within the heating power is controlled of several separately controllable heating fields, distributed across the width of the drying tunnel, in agreement with the measured values of the moisture.
