Stefano replied off-list with the following:

*=====================================
\version "2.12.3"


\relative {


<<  { d2 ~ d ~ d4 ~ d8 r8 s2 s2 } \\
        {
\override DynamicLineSpanner #'padding = #-12.0                 %%that doesn´t 
work either
        \pitchedTrill c4_\startTrillSpan bes \pitchedTrill b4_\startTrillSpan ~ c b2 
~<<  b2 ~ {s4 s8. s16_\stopTrillSpan}>>
        \stemUp
        b2\startTrillSpan ~<<  b2 {s4 s8. s16\stopTrillSpan}>>}>>



}

*==============================

I believe that what he wants is something like this:

\version "2.12.3"

\relative c' {

<<

{ d2 ~ d ~ d4 ~ d8 r8 s2 s2 }

\\

{

\override Voice.TrillSpanner #'direction = #DOWN %% this is the part you 
need to change

\pitchedTrill c4_\startTrillSpan bes \pitchedTrill b4_\startTrillSpan ~ 
c b2 ~

<< b2 ~ { s4 s8. s16_\stopTrillSpan } >>

\override Voice.TrillSpanner #'direction = #UP %% and here we put the 
trillSpanner on top again

b2\startTrillSpan ~ << b2 { s4 s8. s16\stopTrillSpan } >>

}

>>

}



Hope this helps, Stefano!
