application unit 17 downstream fromapplication unit 16 enables high-speed operation ofdevice 1. In this connection, it is important to note that applyingpatch 7 tostrip 9 is a relatively slow job, and only oneapplication unit patches 7 tosuccessive slits 6 whenstrip 9 is fed through at high speed. Moreover, providingapplication unit 17 downstream fromapplication unit 16 allows the operator to stop either one of the application units temporarily for maintenance purposes (cleaning the application unit, changing the reel ofstrip 39 removably supporting patch 7) without interrupting production ofcigarette packets 2. -
Operating unit 15 comprises aroller 21 rotating about arespective axis 22 and having a known peripheral blade (not shown) which rotates aboutaxis 22 and into contact withstrip 9 to formslit 6. - With reference to

control unit 23 will now be described as of the instant in whichelement 31 is detected bysensor 30.Light sources 26 emit a flash of light, and an image is acquired bydetector 24 and processed bycentral control unit 19, to whichdetector 24 is connected (the connection betweendetector 24 andcentral control unit 19 is not shown).Central control unit 19 compares detected values with reference values, and, in the event the detected values are incompatible with the reference values, emits an error signal. More specifically,central control unit 19 compares the position of anedge 32 ofstrip 9 with the position—determined in two areas L1 and L2—of alongitudinal edge 33 ofpatch 7, and compares the position of atransverse edge 34 ofpatch 7 with the position (detected by sensor 30) ofelement 31. - In this way,
control unit 23 is able to determine accurately whetherpatch 7 is correctly oriented and positioned longitudinally and transversely with respect tostrip 9. - The absence of
slit 6 is indicated whendetector 24 fails to receive sufficient light through slot F. - Conveyor 8 (
FIG. 2 ) comprises asuction belt 35 forfeeding strip 9 throughapplication stations FIG. 2 ).Suction belt 35 preventsstrip 9 from moving crosswise to path P, and, at the same time, ensuresslit 6, formed beforehand instrip 9, is held down asapplication unit deposits patch 7 onstrip 9, thus ensuring extremely precise application ofpatch 7 onstrip 9. - The precision with which
patch 7 is applied tostrip 9 is further improved by the particular structure and operation ofapplication units - Application unit 16 (
FIG. 3 ) comprises anapplicator head 37; and aconveyor 38 for feeding astrip 39, removably supportingpatch 7, toapplicator head 37 in a direction crosswise to path P. - In actual use,

generator 47 induce heat in certain areas ofsheet 3′, by virtue ofsheet 3′ containing metal components. - In this way, good-quality seals can be achieved, while at the same time reducing the risk of damage to
sheet 3′ and/or the cigarettes (not shown) wrapped insheet 3′. - This is achieved in an extremely straightforward, low-cost manner by not moving
generators 47. -
Generators 47 are preferably oil-cooled. - Though the
FIG. 5 and 6 embodiment shows twoactuators 49, one for each sealingunit 46, it should be pointed out that, alternatively,movable members 48 may be operated by a single mechanical mechanism. - An embodiment not shown of sealing
assembly 44 comprises a conventional sealing unit, with a heating element, instead of electromagnetic-induction sealing unit 46. -
Device 1 also comprises a packingassembly 50 for inserting wrappedgroup 4 insideouter container 5. - More specifically, wrapped
group 4 may be inserted inside a preformedouter container 5, orouter container 5 may be formed about wrappedgroup 4. Herein, the expression “insert the wrapped group of cigarettes inside the outer container” includes both the above alternatives. - In preferred embodiments not shown, a suction compensation chamber for
strip 9 is provided betweenapplication station 13 andcontrol station 14, and is, for example, of the type described in EP 949174, which is included herein by way of reference. - In other preferred embodiments not shown, a number of sensors, each for detecting the presence of
element 31, are located along path P; in which case,central control unit 19 regulates operation of the assemblies and units ofdevice 1 as a function of the findings of the sensor. - Operation of
device 1 will now be described as a whole, as of the instant in which operatingunit 15 forms slit 6. At this point,strip 9 is fed continuously along path P throughapplication stations patch 7 is applied toslit 6, and throughcontrol station 14 to cuttingstation 10.Sheet 3′ is formed at cuttingstation 10 and fed through areject station 51, where areject unit 52 eliminates anyflawed sheets 3′. - If not rejected,
sheet 3′ is fed to foldingassembly 43, which foldssheet 3′ about group G of cigarettes to form wrappedgroup 4.Inner wrapping 3 is then stabilized by sealingassembly 44. And, finally, the wrappedgroup 4 is inserted insideouter container 5. - In alternative embodiments not shown,
