Abstract
On a cigarette filter assembly machine, (2), a first and second succession of side by side, oppositely-oriented filter-tipped cigarettes are fed to a turnover unit settable to two distinct operating positions for turning over by 180.degree. the cigarettes in one or other of the two successions; the overturned cigarettes being transferred onto the opposite side of the cigarettes in the other succession to form two successions of equioriented, transversely-spaced cigarettes.
Claims13
A method of producing filter-tipped cigarettes (11), the method comprising stages consisting in feeding two side by side successions (21, 22) of oppositely-oriented filter-tipped cigarettes (11a, 11b);
- and in a turnover stage turning over the cigarettes (11a;
- 11b) in a first (21;
- 22) of the two successions (21, 22) so that they are oriented the same way as the cigarettes (11b;
- 11a) in a second (22;
- 21) of the two successions (21, 22);
- characterized in that said turnover stage provides for transferring each cigarette (11a;
- 11b) in a transfer stage in the first succession (21;
- 22) from a first position in relation to the cigarettes (11b;
- 11a) in the second succession (22;
- 21), to a second position on the opposite side of the cigarettes (11b;
- 11a) in the second succession (22;
- 21) as compared with the first position and a given distance from the cigarettes (11b;
- 11a) in the second succession (22;
- 21);
- said transfer stage involving turning each cigarette (11a;
- 11b) in the first succession (21;
- 22) over by 180.degree., to form two successions (21, 22) of equioriented, transversely-spaced cigarettes (11).
A machine for producing filter-tipped cigarettes (11), the machine (2;
- 51) comprising first feeding means (13) for feeding two side by side successions (21, 22) of oppositely-oriented filter-tipped cigarettes (11a, 11b);
- turnover means (24) for turning over the cigarettes (11a;
- 11b) in a first (21;
- 22) of the two successions (21, 22) so that they are oriented the same way as the cigarettes (11b;
- 11a) in a second (22;
- 21) of the two successions;
- and second feeding means (40) for feeding said two successions (21, 22) of equioriented cigarettes (11a, 11b);
- characterized in that said turnover means (24) comprise transfer means (32) for transferring each cigarette (11a;
- 11b) in the first succession (21;
- 22), by turning it over by 180.degree., from a first position in relation to the cigarettes (11b;
- 11a) in the second succession (22;
- 21), to a second position on the opposite side of the cigarettes (11b;
- 11a) in the second succession (22;
- 21) as compared with the first position and a given distance from the cigarettes (11b;
- 11a) in the second succession (22;
- 21), to form two successions (21, 22) of equioriented, transversely-spaced cigarettes (11).
