The bed extension comprises a main, rigid, panel defining an inner recess for shapingly conforming to the cylinder bed, the inner recess of generally quadrangular shape. The web of the U-shape extension plate is telescopingly extensible and the two side legs thereof are extensible with add-on strips, wherein the extensible bed is adjustable in length as well as in width.
