Apparatus for pulping a web of broke advancing downwardly thereto comprises an open tub having at least one generally vertical side wall wherein at least one pulping rotor is mounted for rotation on a substantially horizontal axis. A screw of an axial length substantially greater than the maximum axial dimension of each rotor is mounted concentrically on each rotor and extends horizontally therefrom into the interior of the tub to engage a web of broke entering the tub from above and thereby to draw the web into engagement with the associated rotor.
