In reality, there is a practical limit to what can be or should be stocked in terms of repair parts for a press. Of course, the biggest “bang for the buck” is focusing on the higher probability and higher impact issues, and then, preparing accordingly. By working closely with the OEM, converters can avoid the most critical issues by stocking the right types of spare parts from the beginning. HUman ElEmEnt While presses become ever more automated, there is still a huge part to be played by the operating and maintenance staffs to insure a smooth-running operation. Even though the machines seem to nearly “run themselves” nowadays, the human element in the equation remains the most critical and the most important. By continuously learning through experience and methodi- cal training, both on-the-job (OTJ) and that offered by groups such as Flexographic Technical Association (FTA), operators and maintenance folks will be able to take full advantage of the latest automated features of today ’s advanced flexo presses. The result: the in-plant team, or press crew, will work at the highest efficiency for the maximum benefit of the organization. n About the Author: Tom Jacques is the North American Sales Manager for Flexotecnica, with service and support from North American Cerutti Corporation in New Berlin, WI.
