<p>Packets of cigarettes are directly singly and in succession along a conveyor into a cellophane wrapping machine, and thereafter to a packaging machine which is driven, together with the wrapping machine, by one main motor and incorporates a feed unit supplying wrapper blanks, and a wrapping unit by which each blank is folded about a corresponding group of packets. In the event of an interruption in the supply of packets to the conveyor, the feed unit is decoupled automatically from the main motor and the wrapping unit then allowed to complete a further cycle in which a blank already gummed and positioned by the feed unit can be fashioned as usual into an outer wrapper around a relative group of packets before the main motor is finally shut off.</p> |
