Hello I have to animate an conveyor belt.
But I don’t have a good Idea..?
Do you have a good idea how to do this.
I have made a motion path, and convert it to a Bezier curve, but I can’t make it an open cure.
Also the plates from the conveyor must face always to the surface
Is there a good way to do this?

Your entire model is cached off model bits and no surprise as this is how you historically do models for all other 3d apps. Build it final and then pound the crap out of it.
I attached a file that creates a conveyor belt rig which is built on-the-fly and doesn't require you to build complicated rigs on top of your hard model geometry. The Carve SOP and using NURBs and Mesh primitives is key.
You can substitute your own belt blades in place of the grid place-holder I created. Just make sure your blade aims downt the +Z axis and up is Y as per usual in Houdini.
Right now the rig is pretty basic and doesn't support any of the pulleys rotated arbitrarilly to get a bendy belt but that is entirely possible btw. For now please keep the pullies all on the same plane but to be sure I locked off all the object parms that shouldn't be touched. Just move the pully objects in to place by adjusting the Root and the pully objects.
To support bendy belts, instead of one belt curve, just build two and use the Rails SOP instead of Sweep.
You can add dynamics to the belt after it is extruded but you will have to warp the blades if they are to be bendy. And on and on…
If you want the pully rotation in X to drive things, that's basic math. You know the radius of the pully, the unit divisions of the belt and put the trig in the Carve SOP instead of the $T I have in there.

There's at least one school like the old school!
