Abstract
A method and apparatus of continuously producing a cellular structure wherein plies of flexible sheets are fed under tension, one through a glue station wherein precisely aligned longitudinal lines of adhesive are applied to a first face of one of the plies which are then adhered along said lines, followed by passing the resultant adhered plies as a web through a second station under tension where precisely aligned longitudinal lines of adhesive are applied to an exterior web face, and such web then fed as a continuous loop to intermittent web drive means. The web is intermittently fed into a cutting zone in precise increments and sheared to form successive strips that are forced into an assembly zone where the strips are adhered together to form an expandable cellular structure suitable for direct expansion and use as a honeycomb core. The loop provides a preformed unrestrained surge section ahead of the intermittent feed to accommodate in such section.
