Apparatus for manufacturing of multi-element rods of tobacco industry

An apparatus for manufacturing of multi-element rods of the tobacco industry comprising

• a feeding apparatus (5) designed to feed rod-like elements (S1, S3, S4),
• a transferring apparatus (3′, 3A′) designed to transfer the rod-like elements (S1, S3, S4) or groups (G) of the rod-like elements (S1, S3, S4) from the apparatus (5) feeding the rod-like elements (S1, S3, S4) to a forming apparatus (11), comprising
• a first rotational element (6, 6′) provided with first lugs (16, 16′) immobile relative to the first rotational element (6, 6′) and notches (26, 26′) between the first lugs (16, 16′),
• a second rotational element (7, 7′) provided with second lugs (17, 17′) immobile relative to the second rotational element (7, 7′) and notches (27, 27′) between the second lugs (17, 17′),
• a third rotational element (9) without lugs,
• used to convey the rod-like elements (S1, S3, S4), whereas the notches (26, 26′) between the lugs (16, 16′) on the first rotational element (6, 6′) and the notches (27, 27′) between the lugs (17, 17′) on the second rotational element (7, 7′) as well as the circumferential surface (19) of the third rotational element (9) are adapted to receive and convey the individual rod-like elements (S1, S3, S4) or the groups (G) of the rod-like elements (S1, S3, S4), whereas
• the first rotational element (6, 6′), the second rotational element (7, 7′) and the third rotational element (9) are arranged and adapted to guide the rod-like elements (S1, S3, S4) successively through the first rotational element (6, 6′), the second rotational element (7, 7′) and the third rotational element (9),
• the apparatus comprises the forming apparatus (11) designed to form a continuous multi-element rod (CR), a cutting apparatus (13) designed to cut the continuous multi-element rod (CR) into individual multi-element rods (R),
• characterised in that
• the bottom surfaces (36, 36′) of the notches (26, 26′) on the first rotational element (6, 6′) and the bottom surfaces (37, 37′) of the notches (27, 27′) on the second rotational element (7, 7′) are situated so that the diameter (D2) of a circle having the centre on the axis of rotation (Y) of the second rotational element (7, 7′), inscribed in the bottom surfaces (37, 37′) of the notches (27, 27′) on the second rotational element (7, 7′) is smaller than the diameter (D1) of a circle having the centre on the axis of rotation (X) of the first rotational element (6, 6′), inscribed in the bottom surfaces (36, 36′) of the notches (26, 26′) on the first rotational element (6, 6′).
