Abstract (en)
[origin: EP3123876A1] A filter cigarette manufacturing machine and a filter cigarette manufacturing method according to the present invention are for a double filter cigarette (WFC), which is an intermediate product in a manufacturing process of a filter cigarette (FC). Two perforation lines (16) are formed by irradiating double-width paper (WP) of the double filter cigarette (WFC) with laser beams from a laser perforation device(40). On the other hand, before formation of the perforation lines (16), a glue transfer roller (48) applies glue to a reverse side of a paper web (PW) excluding regions which correspond to the perforation lines (16) and become non-adhesive regions (R1 and R2) extending over an entire circumference of the double-width paper (WP), where the paper web (PW) is used to form the double-width paper (WP). Besides, the present invention also provides a filter cigarette (FC) provided with the perforation line (16) formed in the non-adhesive regions (R1 and R2) of tipping paper (14).
