Abstract. Let $X_1$ be a smooth surface. We study rank $r$ spanned vector bundles $\Ee$ on $X_1\times \PP^2$ whose determinant is of the form $L\boxtimes \Oo _{\PP^2}(1)$ with $L$ a spanned line bundle on $X_1$. We divide them according the behaviour of the dependency locus of $r-1$ general sections of $\Ee$ with respect to the projection $X_1\times \PP^2\to X_1$.
