Replacing the conveyor may be the best option, but would be pretty expensive. I might try to somehow condition the conveyor. You may have slip between the conveyor and drive roller as well as between the workpiece and the conveyor.(both sides of the conveyor may be slipping) If it is slipping on the drive rollers, you can tighten up the roller so it is tighter on the conveyor, this will reduce slip between the drive and conveyor. If it would not screw up your material, you could try some type of belt dressing or other grippy coating. If you don't want to do that, maybe you could take a skim cut off of the conveyor with the sander. I'm not sure if you can raise it that high or if it would work but if you took off the top layer of rubber, it may expose some stickier fresh rubber underneath. Realize that you could screw up the whole machine by doing this but its your call on what you want to do.
