Try wire you're curve in to a resample sop.. that will allow you control 
over how many points you're curve has.. and thus how many copies you'll 
get out of the copy sop. This should allow you're overlapping.

Also.. try the sweep sop instead of the copy sop. This sop is designed 
for this sort of thing. It also optionally takes a reference curve to 
use as an up vector.

Not to complicate things too much since you're new to this.. but 
sometimes I'll take a sphere.. add point normal and upvector to it 
(point sop).. then sweep that around my curve. (gives the same sort of 
result as the tangent stuff everyone else is replying about)... I'll 
take all those spheres as my template to the copy sop.. This gives me 
the sweep functionality of the sweep sop.. plus the copy (stamping!) 
functionality of the copy sop.
