• This collation is joined using a tipping paper patch 3 that is wrapped around the at least one filter rod 2 and a part of each tobacco rod 1.
• Figure la shows a single filter rod 2 disposed between two tobacco rods 1, but it will be appreciated that the collation of rod articles may include several filter rods 2.
• Tipping paper patches 3 are provided by apparatus that applies adhesive to one side of a web of tipping paper and cuts the web to form patches 3.

In this way, when the collation of rods 1, 2 is rolled, the tipping paper patch 3 will be adhered around the circumference of the rods 1, 2, joining them together to form two smoking articles joined end-to-end. This can then be cut through the centre to form two smoking articles.
• the collation of rods 1, 2 and the tipping paper patch 3 are rolled by a rolling drum 4 so that the tipping paper patch 3 is wrapped around the collation of rods 1, 2.
• Figure lb shows the collation of rods 1, 2 and the tipping paper patch 3 when they are received in a flute 5 of a rolling drum 4 after the tipping paper patch 3 has been anchored to the collation of rods 1, 2.
• the flute 5 is formed in the peripheral surface 6 of the rolling drum 4 and comprises a curved recess in which the collation of rods 1, 2 and tipping paper patch 3 are received.

• Each flute 5 extends in an axial direction across the peripheral surface 6, such that the collations of rods 1, 2 move in a direction transverse to their length when the rolling drum 4 rotates.
• the anchorage between the tipping paper patch 3 and the collation of rods 1, 2 is created by a partial wrapping of the tipping paper patch 3 around the collation of rods 1, 2.
• the tipping paper patch 3 extends over the peripheral surface 6 of the rolling drum 4 in a trailing direction. That is, the rolling drum 4 rotates in the direction indicated by arrow 7 and the tipping paper patch 3 extends in the opposite direction, so that it trails behind the collation of rods 1, 2.
• the collation of rods 1, 2 is caused to roll out of the flute 5 and along the peripheral surface 6 of the rolling drum 4 in the direction of arrow 8.

• FIG 2 shows the rolling drum assembly of an apparatus for assembling smoking articles.
• the rolling drum assembly comprises a rolling drum 4 and a roll hand 9.
• the rolling drum 4 has a peripheral surface 6 with a plurality of flutes 5 to receive collations of rods 1, 2 with tipping paper patches 3 anchored thereto, as described with reference to Figure lb.
• the rolling drum 4 rotates in the direction of arrow 7 and the roll hand 9 remains stationary to cause the rolling action previously described with reference to Figure lb. That is, the roll hand 9 causes the collation of rods 1, 2 to roll out of the flute 5 and along the peripheral surface 6 and into an upstream flute, thereby wrapping the collation of rods 1, 2 with the tipping paper patch 3.
• the rolling drum 4 has a receiving position, indicated by line 10. As a flute 5 passes this receiving position 10 a collation of rods 1, 2 is transferred into that flute 5 together with a tipping paper patch 3.
• the collation of rods 1, 2 and tipping paper patch 3 can be transferred onto the rolling drum 4 from an upstream supply drum (not shown).
• the tobacco rods 1, at least one filter rod 2 and tipping paper patch 3 may be supplied by different drums (not shown).
• a flute 5 of the rolling drum 4 receives two tobacco rods 1, at least one filter rod 2, and a tipping paper patch 3.
• the roll hand 9 comprises a leading edge 11 that contacts the collation of rods 1, 2 and pushes it out of the flute 5 as the rolling drum 4 rotates.
• the roll hand 9 also comprises a rolling surface 12 which is parallel to and spaced from the peripheral surface 6 of the rolling drum 4.
• the rolling surface 12 is curved, with a larger radius than the peripheral surface 6 of the rolling drum 4 and centred on the axis of rotation of the rolling drum 4.
• the roll hand 9 is positioned relative to the rolling drum 4 so that, once the collation of rods 1, 2 is pushed out of the flute 5 and is disposed between the peripheral surface 6 of the rolling drum 4 and the rolling surface 12 of the roll hand 9, the collation of rods 1, 2 is slightly compressed. This ensures that the tipping paper patch 3 is tightly wrapped around the collation of rods 1, 2 to facilitate sufficient adhesion between the tipping paper patch 3 and the collation of rods 1, 2.
• a collation of rods 1, 2 is received on the rolling drum 4 in eveiy other flute 5.
• the odd flutes will be considered as a first group of flutes 5a
• the even flutes will be considered as a second group of flutes 5b.
• the first flutes 5a and second flutes 5b are thus alternately arranged around the peripheral surface 6 of the rolling drum 4. Upstream of the roll hand 9, the odd flutes 5a receive a collation of rods 2 and a tipping paper patch 3.
• the even flutes 5b which are disposed in between the odd flutes 5a, are empty before the roll hand 9. That is, the even flutes 5b do not receive a collation of rods 1, 2 before reaching the roll hand 9.
• the tipping paper patches 3 are designed to be wrapped around the collation of rods 1, 2 at least twice, so that two layers of tipping paper circumscribe the collation of rods 1, 2.
• the rolling surface 12 of the roll hand 9 extends from the leading edge 11 of the roll hand 9 in a direction around the circumference of the rolling drum 4. As shown, the roll hand 9 extends a distance equivalent to four flutes 5. In other words, if the space between two adjacent flutes 5 on the rolling drum 4 is considered to be one segment, the roll hand 9 extends the length of three segments around the rolling drum 4. Therefore, when a collation of rods 1, 2 is rolled, it will be rolled from an odd flute 5a, over an even flute 5b, over a second odd flute 5a, and will reach a second even flute 5b as the rolled collation of rods 1, 2 reaches the end of the roll hand 9. That is, the collation of rods 1, 2 is rolled over three segments of the rolling drum 4, from an odd flute 5a to an even flute 5b.
• the arc length may equate to between 1 and 3 rotations of the collation of rods 1, 2 over its circumference. Therefore, a collation of rods 1, 2 may be rolled between 3 and 9 times over its circumference, preferably at least 3.5 times. It will be appreciated that the exact number of times a collation of rods 1, 2 is rolled will depend on the diameter of the rods 1, 2, so will vary if the eventual smoldng articles are slimmer or thicker. It has been found that by rolling the collation of rod articles l, 2 at least 3, and up to 9, times over their circumference, the tipping paper patch 3 is wrapped twice around the collation of rods 1, 2 and is thoroughly adhered.

• the first suction holes 14 are arranged in two rows of first suction holes 14, two suction holes 14 in each odd flute 5a. These rows of first suction holes 14 are aligned along the peripheral surface 6 of the rolling drum 4. That is, each row of first suction holes 14 is positioned the same distance from a centre line 17 of the peripheral surface 6 of the rolling drum 4.

• each flute 5 of the rolling drum 4 also comprises a pair of third suction holes 34.
• These third suction holes 34 are positioned closer to the centre line 17 of the rolling drum 4, that is, they are disposed between the first or second suction holes 14, 15.
• the third suction holes 34 are provided with suction upstream of the roll hand 9 and downstream of the roll hand 9, to retain the unwrapped filter rod 2 components upstream of the roll hand 9, and the filter part of the wrapped collation of rods 1, 2 downstream of the roll hand 9
