Looping Animation


I’ve to do a simple looping animation which’s objects moving behind each other along a spline (like a conveyor belt). Since i’ve a hard time with programming, i’ve animated one object and let the others spawn by
a time-offset. Now i’ve the problem that i that can’t get ride of each component when the animation is done. I’ve done a simple project example for better understanding since my english isn’t that good.

And here are some screenshots of my blueprint:


Also it seems i’ve a problem with the “delta time”. I think the objects vary by distance when the frame drops. But i dont know how to fix this.
Any help would be appreciated.
