Abstract A collapsible cellular partition unit is formed by spacing parallel sheets and locating therebetween parallel, longitudinally extending wall sheets, each wall sheet having one longitudinal edge secured to one spaced sheet and the other edge secured to the other spaced sheet. For the continuous manufacture of such units, the spaced sheets are formed by two moving webs to which longitudinal glue lines are applied. The wall sheets are formed by webs moving between and with the first webs. The wall sheet webs are slit from a single stock roll and are scored to form longitudinal flaps to adhere to the glue lines on the respective first two webs. The first two webs are scored to form the outer wall portions of the partition unit. A partition structure of desired size may be built up by assembling the required number of partition units, the units being secured to each other by glue areas on their spaced sheets. The partition structure may then be secured in a collapsed position within a collapsed container and both shipped as an integrated package unit for simultaneous setup.
A collapsible cellular partition unit comprising: a plurality of cellular longitudinal rows, each row consisting of two spaced flexible sheets forming top and bottom surfaces of said cellular longitudinal row; a plurality of substantially parallel equidistant wall sheets forming cells in said cellular longitudinal row; each wall sheet having a body portion and longitudinal edges terminating in top and bottom flaps which extend in opposite directions to give the sheet a Z-shape; the top and bottom flaps of each of said longitudinal edges in each wall sheet being secured to the respective top and bottom spaced sheets along substantially parallel glue lines; said plurality of adjacent rows being bonded along said spaced sheets to form a double thickness of the intermediate spaced sheets of said partition unit; and one end wall of each row being integral with the top sheet and extending downwardly and parallel to the wall sheets and outwardly to form a flange secured to the end of the flexible bottom sheet of the longitudinal row while the other end wall of the row is integral with the bottom sheet and extends upwardly parallel to the wall sheets and outwardly to form a flange which is secured to the end of the flexible top sheet of the longitudinal rows.
