Abstract
On hinge-lid packets, a collar (31) is usually arranged in a packet portion (10) and is fastened with a lower partial region of collar front wall and collar side flaps (33, 34) to inner sides of packet front wall (12) and packet side walls (14, 15) by gluing. An upper region of the collar (31) protruding out of the packet portion (10) forms visible surfaces (54). These are preferably provided over their whole area with printing or a printed color layer (40) and an outer protective layer (42). Fastening surfaces (51, 52) lying in the packet portion (10) are free of printed color layers and protective layers.

Hinge-lid packet made of cardboard, comprising a packet portion (10) and a lid (11) which is connected by a hinge in a region of a lid rear wall (18) via a line joint (26) to a packet rear wall (13), and a collar (30, 31) being arranged in the packet portion (10) and attached with lower fastening surfaces (43, 44;
- 51, 52) in a region of a collar front wall (32) and collar side flaps (33, 34) to an inner side of a packet front wall (12) and by packet side walls (14, 15), and of which a region protruding from the packet portion (10) forms free visible surfaces (41, 54), characterized by the following features:
- a) the free visible surfaces (41, 54) end in a region of an upper front closing edge (27) formed by the packet front wall (12) and in a region of upper side closing edges (28, 29) formed by the packet side walls (14, 15) and border there the fastening surfaces (43, 44;
- 51, 52);
- b) of the free visible surfaces (41, 54) of the collar front wall (32) and collar side flaps (33. 34) which protrude from the packet portion (10), at least one of said free visible surfaces is provided with a printed color layer (40);
- c) the printed color layer (40) is covered by a protective layer (42);
- and
- d) the printed color layer (40) covered by the protective layer (42) extends over a region of the said at least one of said free visible surfaces in such a way that the fastening surfaces (43, 44;
- 51, 52) of the collar front wall (32) and collar side flaps (33, 34) are free of any of the printed color layer (40) and protective layer (42).
A device for manufacturing separate blanks for forming collars (31) of cigarette packets of the hinge-lid type, blanks for the collars (31) being capable of being detached in succession via transverse stamped-out lines (73) from a continuous material web (57) which is made of thin cardboard and which has, on regions thereof corresponding to free visible surfaces of each collar which protrude from the packet, a printed color layer (40) covered by a protective layer (42), wherein:
- a) the material web (57) is conveyed downstream through a cutting assembly (68) for detaching the collars (31) during continuous conveying of the material web (57) in a conveying direction,
- b) upstream of the cutting assembly (68) there are arranged preliminary rollers (66, 67) for controlling forward movement of the material web (57) in the conveying direction,
- c) a printed marks reader (74) is arranged above or below the material web (57) to detect printed marks (58) disposed on a web side facing the printed marks reader (74),
- d) the cutting assembly (68) is controlled by the printed marks reader (74), in respect of the exact application of the stamped-out lines (73), to detach the blanks from the web (57), and
- e) conveying members including conveying rollers (70, 71) carry away the collars (31) as they are detached from the material web (57) in the region of the cutting assembly (68) to create a distance from the material web (57).
A method of manufacturing blanks for collars (31) as part of a hinge-lid packet, comprising the steps of:
- a) applying a printed color layer (40) and a protective layer (42) covering the printed color layer (40) on a continuous material web (57) of thin cardboard, said material web comprising the blanks used for forming the collars (31), such that the printed color layer (40) and the protective layer (42) are applied to the material web (57) in a partial region of each of the blanks such that the partial regions of each of the blanks are spaced apart from one other in the longitudinal direction of the material web (57), with the printed color layer (40) and protective layer (42) being delimited by separating lines (53, 55) from free fastening surfaces (51, 52) lying on a same side of the material web (57);
- and
- b) severing the blanks from the continuous material web (57) of thin cardboard.
