Abstract
Apparatus having laminating rolls for laminating continuous strips of different kinds of material together wherein all of the continuous strips enter the nip between the laminating rolls from one side of a plane tangent to each of the laminating rolls at the nip. Also, apparatus having rotary cutting and creasing rolls located before the laminating rolls form most of the cut lines for the carton blank without changing the continuity of a continuous strip of a relatively rigid material so that it can be pulled through the laminating rolls. In those instances wherein two carton blanks are formed at the same time, scrap removal apparatus is provided for removing scrap located between the two carton blanks.
