• Parallel top and bottom faces le, if extend between the front and rear faces la, lb, and side faces ic, id of the pack 1 and comprise the smallest faces of the pack 1.
• the inner frame 3 extends over the cigarette bundle on at least part of the front, rear, side and bottom faces la - le of the pack 1.
• the inner frame 3 is formed from a single- piece flat blank of card 3', as shown in Figure 4.
• the blank 3' comprises a number of connected panels separated by fold lines 4.
• the fold lines 4 are lines of weakening formed in the blank 3' and are shown in dashed lines in Figure 4.
• the blank 3' may be cut from a continuous web 5 of card by a cutting machine (not shown).
• the cutting machine may also provide the fold lines 4 by an embossing tool, creasing knife or scoring blade.
• the blank 3' comprises a bottom panel 3e connected between a front panel 3a and a rear panel 3b.
• First side panels 3c, 3d extend from side edges of the front panel 3a.
• Second side panels 3g, 3h extend from side edges of the rear panel 3b.
• Top flaps 3f extend from an end edge of each of the outer side panels 3c, 3d remote from the bottom panel 3e.

• Figure 5 shows a sequential schematic view of a method and apparatus for
• a continuous web 5 of card to form the inner frame blanks 3' is supplied from a roll to a cutting station 6.
• the cutting station 6 cuts individual inner frame blanks 3' from the web 6 and also forms the fold lines 4 as lines of weakening in the blank 3'.
• the cutting station 6 may include a creasing knife to form the lines of weakening in the blank 3'.
• the blank 3' is then fed to a folding station 7 where the blank 3' is folded into a receiving "clam-shell" configuration in preparation for receiving a bundle of cigarettes 2 in a later stage of the manufacturing process.
• the folding steps of the inner frame blank 3' are shown in more detail in Figures 6A to 6C.
• the blank 3' starts in the flat configuration shown in Figure 6A.
• the outer side panels 3c, 3d and the inner side panels 3g, 3h are folded by approximately 90 degrees to extend approximately at right angles to the front and rear panels 3a, 3b respectively, as shown in Figure 6B.
• the front and rear panels 3a, 3b are then folded towards each other about the bottom panel 3e into the clam-shell receiving configuration shown in Figure 6C.
• the front panel 3a of the blank 3' is slightly wider than the rear panel 3b. This is shown in Figure 4 by dimension 'a' being slightly greater than dimension 'b'. This enables the blank 3' to be accurately folded into the receiving configuration, with the inner side panels 3g, 3h sitting inside the outer side panels 3c, 3d. This helps prevent the inner and outer side panels 3c, 3d, 3g, 3h abutting during the folding of the blank 3'.
• the front and rear panels 3a, 3b are not parallel to each other but diverge away from the bottom panel 3e.
• the front and rear panels 3a, 3b may extend at an angle ⁇ relative to each other by around 10 to 20 degrees.
• This divergence provides a wider opening 8 opposite the bottom panel 3e (see Figures 6C and 7) for insertion of a cigarette bundle in a later manufacturing step described below.
• This provides a tolerance to compensate for blank 3'/cigarette bundle misalignment in the manufacturing process. This means that manufacturing jams are avoided, the machinery requires less precise calibration which allows for more cost- efficient machinery. Also, higher-speed of manufacture is achievable.
• each outer side panel 3c, 3d proximate the bottom panel 3e overlies the respective edge of the inner side panel 3g, 3h proximate the bottom panel 3e.
• the outer and inner side panels 3c, 3d, 3g, 3h do not entirely overlap, their adjacent edges overlapping is sufficient to ensure that when the inner frame blank 3' is closed around a cigarette bundle in a subsequent manufacturing process (described below), the outer and inner side panels 3c, 3d, 3g, 3h slide over each other and do not abut or snag on each other.
