To know that every single 3 "3T is working properly at any time, because an oscillograph is built into the control cabinet, which can be switched to every single cell and allows the output signals of the STFTT to be observed not aa web and elimination of defective inexpensive. the same place made "" 5s extent therefore opportunities provided "ground, dl · to save from the scanner supplied information and aur right time, namely when the material has reached the Ausscheideort" wlederzuegeben. Bas can be done in such a way that a drum rotates synchronously with the feed rollers for the material. This contains a suitable number of movably attached pins on its circumference, which are knocked out by a magnet actuated by the signals from the scanning device. When the drum rotates, these pins release contacts after a time, which depends on the distance between the testing device, the ana * separating device and the speed of the web of material, which in turn initiates the activation of gate directions for the removal of the defective stacks of material, ζ 3 cutting devices or marking devices, cause *

Until pins are moved back to their original position by a mechanical device after contact is made. · They are excreted can of course also be done by other institutions. The possible chains mentioned above are therefore only examples · Every person skilled in the art is in the leg «to name more immediately ·

31 «The storage of similar information can also take place in a form other than that specified *. For example, a magnet activated by the signals from the direction of the gate can punch a hole in a continuously moving "strip of paper. The speed of the paper strip is naturally in a certain ratio to the feed rate of the material and the location of the elimination of the faulty style. her paper strip is now scanned by a photoelectric device that emits a signal "as soon as the hole under the scanner element appears · This signal now operated dl" actual Äusscheidungsvorrichtung · As "in" another way to store the information is given * by the signals of the test apparatus to put a mark on a belt running at a suitable speed, which is then scanned photoelectrically as described above and the desired function is used as an amv device for separating out the defective material.
