The invention relates to a device and a method for impregnating filaments, wherein the filaments form a roving. The device comprises a barrel () having at least one groove () formed in circumferential direction of the barrel, an inner space formed along the center axis of the barrel, and at least one recess () which forms a connection between the inner space and the groove. The recess includes a cylindrical section (), a conical section () and a pocket section (). By means of said device and according to the method, a polymer material can be pressed successively from the inner space through at least the cylindrical section and the conical section into the groove to impregnate the filaments of the roving which is drawn through the groove.
