Although you can't see it in your particular example, I think your two
Reverse functions would lead to reversed partitions, so I got rid of them.
Then it's a matter of following directions for Partition in Help. The only
issue is computing kL. The following way is a bit complicated. Perhaps
someone will post a simpler way.

n = "10101111"; 
r = 3; 
p = Characters[n]; 
kL = r + 1 - Mod[Length[p], r, 1];
kR = r; 
z = Partition[p, r, r, {kL, kR}, "0"]
