So... my best recommendation would be to mimic the example auto-runner game that comes bundled with construct 2. Essentially, you're going to be working with one reel... twice.
1. Make a long strip with your various results. Have it begin to bullet downward.
2. Once the strip has travelled almost its height in distance, spawn another one directly above the first.
3. Let it play endlessly. This will create the illusion of a reel.
