A partitioning pack of the kind shown in Figures 4 and 5 is manufactured in such a way that the ends of its transverse divider walls terminate short of the ends of the longitudinal divider walls thereby leaving exposed portions 22 when the pack is in its flat condition. Such portions 22 are readily locatable thereby enabling the pack to be expanded by automatically operating machinery provided with means for engaging the portions 22 and displacing them to cause relative hinging of the divider walls into the cell-defining condition of Figure 4. |
