Apparatus with heating surfaces with homogeneous heat distribution

摘要

the invention relates to a device with a heated surface of homogeneous heat distribution fully electrically hochleitfu00e4higes fleece, which is electrically non-conductive fibers and electrically conductive fibers includes a control unit, by means of which a voltage adjustable is a f for achieving the desired heat output required flow of current in the device to ensurelines, by which the contact to the control unit for data and / or signalaustausch and / or a supply of the web can be produced with electric energy is electrically conductive fibers and the density is so high that in an adjacent a flow of current into voltage. mm, and to increase the capacity for a given adjacent tensionthe operating voltage, the control unit for the voltage to the voltage "s u1" increased, then return to the output voltage, in the case that the value of the heat output remains below the set point, the control unit to a further voltage "s u2" created with "a u2" greater than "a u1 ', and in casethe value of the heat output is still below the set point, the control unit to a further voltage "a u3" created with "a u3" greater than "a u2", and in the case that the value of the heat output remains below the set point, the above steps n times, using the voltage "s and" greater than "a -", with i = 1 to n - 1).
