2134661 9322134 PCTABS00027 According to the invention, the supply (11) of an adhesion and release agent respectively to the surface of a Yankee-cylinder (1) from which the paper web is removed with the aid of a doctor blade (5) is controlled as a function of a signal from a gauge (20) which measures web tension and which is located between the cylinder (1) and the device (7, 8, 9) by means of which the web is rolled-up. When the degree of crêping is constant, an increase or decrease in web tension indicates that adhesion has increased or decreased respectively, resulting in a change in the setting of the supply device (11, 12). The invention also relates to a suitable web tension gauge to this end.
