Abstract
An apparatus for reading photocell markings applied at equal intervals on the decorated side of a material web run through a packing machine for the continuous manufacture of separatable packages provided with transverse crease lines in which a cylindrical monitoring element which contacts and is rotated by the crease lines functions to periodically actuate an electrical switch which in turn activates a photocell located close to the web when a photocell marking is calculated to pass.
