Abstract

1413603 Packaging STONE CONTAINER CORP 16 July 1973 [31 Aug 1972] 33816/73 Heading B8C A package is produced using two substantially rectangular first and second blanks 12 and 13, respectively, by placing the goods 52 to be packaged on a central panel 15 of the first blank 12, folding side wall panels 17 and longitudinal flanges 21, 23 of the first blank about the goods 52, folding the second blank 13 about the remaining exposed faces of the goods and securing side wall panels 31 of the second blank 13 to the flanges 21, 23. The first blank may also include transverse flanges 25 which may overlie or underlie the panel 29 of the second blank 13 to which they are secured. The securing may be by glue provided on the flanges 21, 23, 25 or the marginal areas of the second blank, adhesive tape, staples or brads. A glued seam may constitute a weakened seam for opening or a tearstrip tape may be used between the flanges 21, 23 and the side wall panels 31. First blanks 12 are supplied from a magazine to a first station whereat the goods 52 are positioned on the blanks and from which the blanks and goods are moved downwardly to a second station past stationary folding members which fold the side wall panels 17 upwardly. The longitudinal flanges 21, 23 may be folded prior to, simultaneously with or after the folding up of the side wall panels 17. The goods and the U- folded first blanks are then moved laterally to a third station by a pusher such as 58 or 127, Fig. 11 (not shown), which also supports the goods. The second blanks 13 are supplied from a magazine during movement of the first blanks 12 and goods 52 between the second and third stations or at the third station or at a fourth station, and may be folded downwardly about the goods by a vertically reciprocable U-shaped forming device or by moving the first blanks, the goods and the second blanks upwardly past stationary folding members. The transverse flanges 25 may be folded down at the third station or during movement of the first blanks 12 past ploughs located between stations. When the blanks are glued together, the assembled packages may be pushed vertically or laterally into a compression chamber.
