Benefits of technology

[0011] The object of the present invention is to provide a method and a device for use in the assembly of packets containing tobacco products, such as will be unaffected by the drawbacks described above.

Problems solved by technology

In the event of a break in production occurring and the machine being brought to a standstill, so that the time elapsing from the moment when the adhesive is applied to the moment when the glued portions are bent and joined becomes long enough for the bonding properties of the adhesive to be degraded, the packets emerging from the restraint means may lose their stability and certain of the glued and joined parts may separate and lift, with the result that the packets are rendered defective and must be discarded.

Embodiment Construction

[0018] With reference to the drawings, numeral 1 denotes a portion of a wrapping line, in its entirety, on which packets 2 for tobacco products are assembled in a packaging machine.

[0019] The wrapping line follows a predetermined path P along which sheets 3 of wrapping material, referred to commonly as blanks, or diecuts, are caused to advance in succession by suitable feed means of conventional embodiment (not illustrated in the drawings), following a feed direction denoted F.

[0020] Located along the aforementioned wrapping path P are components 4 serving to apply a layer or dab of cold-setting adhesive, denoted 8, on selected areas of the wrapping material, and folding means 5 such as will fashion an enclosed packet about a relative group 6 of cigarettes already enveloped, typically, in a leaf of metal foil paper.

[0021] In the example of FIG. 1, the wrapping line 1 passes through a first and a second folding station illustrated schematically as two blocks 5a and 5b, positioned ...

Abstract

Cigarette packets are assembled by a method that involves dabbing or spraying a cold-setting adhesive onto selected areas of a blank fed along the wrapping line of a packaging machine, whereupon the blank is folded to form a packet; should there be a break in operation of the machine following the application of the adhesive, persisting for a certain length of time, the method includes a heat-reactivation step whereby the adhesive applied previously to the blank is warmed to a given temperature so as to restore its bonding properties and guarantee the ultimate stability of the assembled packet.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a method and a device for the assembly of packets for tobacco products. [0002] Cigarette packets are composed conventionally of an inner wrapper, substantially parallelepiped in shape, fashioned generally from metal foil paper and enveloping a group of cigarettes, for example twenty in number, and an outer wrapper that can be either of rigid or of soft type. [0003] In the case of a rigid packet, which typically has a hinged lid, the outer wrapper is fashioned from a flat diecut blank of paperboard prepared with longitudinal and transverse crease lines and cuts serving to delimit a plurality of panels and flaps that will combine, after a succession of folding operations, to form the structure of the outer wrapper. [0004] In the case of a soft packet, the outer wrapper is again fashioned by completing a succession of folding operations, in this instance on a sheet of pliable paper separated by a cutting operation from...
