Abstract

A method of cutting blanks from an elastic paper comprises the following steps: removing a single elastic paper web of indefinite length from a mother roll; longitudinally cutting the single web, as it runs off the mother roll, into a plurality of paper panels; guiding the running paper panels in pairs into a superposed, face-to-face relationship to form at least one running superposed paper panel pair; guiding the running paper panel pair between cooperating cutting rollers of a rotary cutter and cutting the blanks from the running paper panel pair by the cutting rollers alternatingly from opposite sides of the paper panel pair while countersupporting the paper panel pair by the momentarily non-cutting cutting roller.
