A method and apparatus for forming cellular cores from sheet stock of paper, metal or plastic for use in the subsequent formation of laminated cellular panels, or for use independently to provide sound and thermal insulation. The process comprises the steps of feeding two or more webs of sheet material to be formed into the core; joining the webs by applying spaced lines of adhesive or the like between the webs along their direction of feed, bringing the webs into contact so as to cause them to join along said first applied lines of adhesive; applying spaced lines of adhesive or the like, spaced to lie between the previously applied adhesive lines on an outer face of the joined webs; simultaneously cutting a group-strip equal in length as measured along the web to the thickness of two or more layers of the final core product from the adhered webs transverse to their direction of movement; and packing and simultaneously cutting said group-strip into two or more strips by moving them transverse to the direction of web feed to simultaneously form a plurality of layers of cellular cores of selected thickness. Apparatus suitable for performing the method is provided comprising supports for two or more supply rolls of web sheet material; means for feeding the sheet material from the supply rolls; sheet joining means such as adhesive applicators and laminating rolls arranged in the path of web feed for applying spaced lines of adhesive between the web surfaces; a final adhesive applicator for providing adhesive on the outer surface of one of said webs; pressure applying means for bringing two or more of the adhesive stripped web surfaces into contact to bond same along the first lines of adhesive application; cutting means for cutting group-strips equal in length as measured in the direction of web feed to the thickness of two or more layers of the cellular core product from the advancing web transverse to the direction of movement; and packing-cutting means for simultaneously packing the group-strips against the strips of previously cut group-strips and cutting the group-strips into a plurality of separate strips equal in length as measured along the web to the thickness of the cellular core product, said packing means packing two or more tiers of strips simultaneously.
