   626 For the proof of xxxx below we will need the following observation on the action constructed above.

   627 Let $b$ be a blob diagram and $p:P\times X\to X$ be a family of homeomorphisms.

   628 Then we may choose $e$ such that $e(p\ot b)$ is a sum of generators, each

   629 of which has support arbitrarily close to $p(t,|b|)$ for some $t\in P$.

   630 This follows from the fact that the
