AbstractLet X⊂Pr be a variety of almost minimal degree which is the projected image of a rational normal scroll X̃⊂Pr+1 from a point p outside of X̃. In this paper we study the tangent spaces at singular points of X and the geometry of the embedding scrolls of X, i.e. the rational normal scrolls Y⊂Pr which contain X as a codimension one subvariety
