ABSTRACT:
For a method for heat-treating textile material, and for a tenter for carrying out the method, it is proposed to control the textile web velocity as a function of the point on the treatment path at which the maximum deviation in the amount of energy spent per unit time occurs. To determine this point on the treatment path it is not necessary, therefore, to measure the momentary temperature of the textile material directly or the temperatures of the treatment medium flowing in and out. Instead, it suffices to determine the individual valve positions which indicate the amounts of energy supplied per unit time, and to infer therefrom the site of the treatment path where the drying process is completed and the fixing process sets in.
