The general goal of the research is to reduce loss of productivity, failure and downtime and the percentage of waste in production in the company, which is already committed to and successful in applying standards, raising the quality of service, as well as occupational safety and environmental protection. In this scientific paper a mechatronic subsystem is designed and implemented, as an addition to the hot-stamping production line, which would monitor whether there are present (and whether there are in quantities enough of) each of the three thermoplastic, metallized strips, which line the product - profiled lath. When it is detected and recognized that the tape will soon be used up, the sub-system automatically signals this with turning off heating of the slat and activating a sound alarm, attracting attention of the human operator. The heater switches off automatically if the strip loss has occurred (event driven system), in order to prevent deformation of the slat profile. The subsystem includes automatic monitoring of the remaining amount of tape, alarm notification in case of imminent disappearance of the tape, with the heater turned off and alarming the operator. The human operator then has enough time to replace the tape (approximately five to ten minutes, depending on the product). The subsystem described above is designed, built, implemented, tested and put in operation.
