ABSTRACT:
A tag size differentiating system for tag printing machines. The system determines the length of tags in a continuous tag web consisting of a series of identical tags having one of a predetermined set of possible lengths. The system includes means for monitoring the distance the continuous tag web is advanced and sensing means for detecting indicia separating the individual tags. The system comprises a CPU and a memory for storing the possible tag lengths. The CPU determines the distance the tag web is advanced form the time and indicia is detected until the next indicia is detected and compares this distance to the possible tag length. Onthe basis of the comparison, the CPU determines the length of the individual tags in the tag web. The system does not begin the length determining process until the indicia at the trailing end of the initial tag is detected to prevent erroneous length measurements.
