You have a nice machine!
That adhesive strip was probably a label to identify which line it was on, and the machine number, for when it must be pulled and actually worked on, so it gets back where it belongs. It might also have been the service register for keeping track of regular maintenance. When a machine gets used non-stop like they did, you must do constant upkeep to stay in business. (Think thread, lint, dust, etc.)
