A hood-shaped foil covering an object is heat-shrunk around the object by displacing the object covered by the foil along a generally straight path in a transport direction past a stationary heater which is directed at an acute angle to the direction. These mechanisms and methods for interacting with a process diagram may allow for a user’s enhanced interactive experience with the process diagram. Each first-axis conductor assembly includes a plurality of first-axis conductor cells that are interconnected by first-axis conduction lines.
