ABSTRACT:
The invention provides an improved method of forming one or more box blanks (20) from a generally-rectangular sheet of material, comprising the steps of: providing a frame (28) for supporting and guiding the sheet; placing a sheet of material on the frame; controllably moving the sheet in a longitudinal direction relative to the frame; providing at least one longitudinal score line (21) on the sheet as the sheet moves relative to the frame; punching a first hole in the sheet; cutting a first slot (23) in the sheet between one longitudinal edge thereof and the first hole; punching a second hole in the sheet at a position spaced transversely across from the first hole; cutting a second slot (23) in the sheet between the other longitudinal edge thereof and the second hole; providing a transverse score line (22) on the sheet between the first and second holes; punching longitudinal slots in the sheet to severe the flaps (24) from the glue tab (27); and cutting the sheet to the length required for the desired shape and dimensions of the box; thereby to provide a creased and slotted box blank.
