Abstract

1,202,107. Printing apparatus. DRUCKMASCHINENWERKE LEIPZIG VEB. 9 Oct., 1968 [9 Oct., 1968], No. 47772/68. Heading B6C. In order to control the quality of printing in a web-fed rotary multi-colour multi-unit printing machine any possible deformation of the web is monitored at locations before the web enters the first unit, between every unit and after the web leaves the last unit such monitoring is effected by using pairs of web guiding rollers 3, 8/4, 8/5, 8/6, 8/7, Fig. 1, the lower roller of each pair being allowed to swing about the axis of the upper roller should variations in the tension of the moving web occur. Such movement of the lower roller will alter the distance between a flat surface such as 14, Fig. 2, and an air jet issuing from a nozzle 15, which, in consequence, will cause an alteration in the reading of a manometer 13. Should the web break the machine will automatically stop as movement of any one lower roller through an arc equivalent to a drastic loss of tension will uncover electrical contacts, controlling the machine drive, which are placed in the associated manometer. Instead of pneumatic electrical or optical monitoring devices may be used.
