  • Patent number: 5309697
    Abstract: A packaging machine for individual flat strip-like articles, in particular chewing gum strips (10), comprises means for cutting (110) and supplying (100), wrapping (300) and grouping (400; 500) of the individual articles. The packaging machine comprises a first fast section through which the articles pass continuously, i.e. substantially without retardations or accelerations. In this machine section the chewing gums are first cut from sheets (20) to strips (10) in a cutting device (110) and thereafter individually wrapped, a turning drum (340) possibly being employed. Subsequently, they are combined to groups in a grouping means (400; 500). In this second machine section the chewing gum groups are further conveyed intermittently in cycles with lower speed to a collective packing machine. By exchanging components in the grouping means of the fast machine section the articles can be combined to groups different in number and arrangement.
