Abstract
Abstract A device for re-orienting and redistributing hinge-lid packets of cigarettes for application of sealing strips or revenue stamps to the hinge-lids. A first conveyor unit receives the packets, disposed on edge and contacting one another with their wide sides, and having their hinge-lid portions facing away from one side of the conveyor unit. The first conveyor unit moves the packets gradually to a second conveyor unit. This unit moves more rapidly than the first, to space the packets apart. It cooperates with a deflector disk and a narrow overhead belt to turn each packet so that it travels to the delivery end of the second conveyor unit, with the hinge-lid portion facing forward, toward a machine for applying a seal strip or the like.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
361 words
A device for preparing hinge-lid cigarette packets for sealing, comprising a first conveyor belt for packets filled with cigarettes, each packet having a pair of wide sides, a pair of long narrow sides, and a pair of short narrow end portions, one of which comprises a hinge-lid, the conveyor belt being disposed to receive each packet, positioned transversely of the conveyor belt in an initial side-by-side contact relationship wherein the received packet rests on one of its long narrow sides with the wide side of the packet contacting wide sides of preceding and following packets and the conveyor belt being driven to advance at a corresponding speed, a second conveyor belt driven to advance at a higher speed than the first conveyor belt for modifying the initial relationship of the packets for spacing the packets from one another on said second conveyor belt, and to advance the so-spaced packets to a station for applying strip-like material to the hinge-lids, and turning means disposed in an upstream portion of said second conveyor belt, said turning means comprising; a narrow driving belt positioned parallel to and spaced above a portion of the second conveyor belt and normally contacting portions of the long narrow sides of the packets adjacent the ends thereof comprising the hinge-lids; a deflector unit positioned above a portion of the second conveyor belt which portion normally underlies portions of the long sides of the packets remote from the hinge-lids, for deflecting the spaced packets from their being positioned transversely of the second conveyor belt; and means for moving the narrow driving belt in the same direction and at the same speed as the second conveyor belt, so that a portion of an upper long narrow side of each packet, adjacent the hinge-lid, is engaged by the narrow driving belt, upstream of the deflector unit to provide a narrow belt-contact area on and travelling with the packet and narrow driving belt past the deflector unit, and thereby to provide in said area a pivot, similarly travelling for turning the packet about the pivot upon said deflecting, into a position longitudinal of the second conveyor belt and with the hinge-lid facing forward.

Claim 3
Dependent Claim
20 words
A device according to claim 1, wherein said deflector unit comprises a rotatable disk parallel to the second conveyor belt.
