Abstract

Method for manufacturing of multi-segment rod-like articles (25, 25′, 25″) of the tobacco industry in an apparatus (2) for manufacturing multi-segment rods (6) or segment rods (6′, 6″) comprising the steps of: feeding rod-like segments of at least one kind (A, B, C, E, F) constituting a multi-segment rod-like article (25, 25′, 25″); putting together rod-like segments (A, B, C, E, F) in a segments train (ST) on a wrapping material (7); manufacturing a continuous segment rod (CR′, CR″) or multi-segment rod (CR) containing rod-like segments (A, B, C, E, F) wrapped by the wrapping material (7), whereas the segments are pushed together or cavities are left between the segments; and cutting the continuous segment rod (CR′, CR″) or multi-segment rod (CR) into multi-segment rods (6) or segment rods (6′, 6″) containing any combination of H rod-like segments (A, B, C, E, F), double rod-like segments (A, B, C, E, F) and halves of rod-like segments (A, B, C, E, F), whereas at the time of cutting of the continuous multi-segment rod (CR) the multi-segment rods (6) or the segment rods (6′, 6″) move in a longitudinal direction (T1); then changing conveying direction of the multi-segment rod (6) or the segment rod (6′, 6″) from the longitudinal direction (T1) to a transverse direction (T2), and fixing the end segments (D) to the multi-segment rods (6) or the segment rods (6′, 6″), conveyed in the transverse direction (T2) in an end segment fixing apparatus (3) adapted to manufacture multi-segment rod-like articles (25, 25′, 25″). The method is characterised in that after the change of the conveying direction of the multi-segment rod (6) or the segment rod (6′, 6″) from the longitudinal direction (T1) to the transverse direction (T2), and before fixing the end segment (D), a step of checking quality the manufactured multi-segment rods (6) or the segment rods (6′, 6″) is performed at a measuring unit (9) and defective multi-segment rods (6) or the segment rods (6′, 6″) are rejected, next feeding the multi-segment rods (6) or the segment rods (6′, 6″) to a compensation unit (13) for storing the multi-segment rods (6) or the segment rods (6′, 6″) and for compensating the rejection of the multi-segment rods (6) or the segment rods (6′, 6″), and then feeding the multi-segment rods (6) or the segment rods (6′, 6″) from the compensation unit (13) to the end segment fixing apparatus (3) so that the end segment fixing apparatus (3) is continuously fed with the multi-segment rods (6) or the segment rods (6′, 6″).
