#### Streszczenie

For every Lie groupoid $\Phi$ with $m$-dimensional base $M$ and every fiber product preserving bundle functor $F$ on the category of fibered manifolds with $m$-dimensional bases and fiber preserving maps with local diffeomorphisms as base maps, we construct a Lie groupoid ${\cal F} \Phi$ over $M$. Every action of $\Phi$ on a fibered manifold $Y\to M$ is extended to an action of ${\cal F} \Phi$ on $FY\to M$.
