BEST MODE FOR CARRYING OUT THE INVENTION With reference to Figure 1, number 1 indicates as awhole a labelling machine for labelling containers 2,suchasbottles,flacons,cansorcontainersofthi ssort,adapted to contain a pourable product, preferably apourable food product. In particular, labelling machine 1 is configured fo rlabelling containers by means of applying labels 3obtained by cutting a web 4 of labelling material o ntocontainers2. According to this preferred and non-limitingembodiment, labels 3 are glued labels, i.e., strips oflabelling material that are cut at predetermined le ngthsfrom web 4 and then provided (in particular sprinkl ed)with glue before their application on the respectiv econtainers2. Preferably,web 4 is initially wound around one ormore reels (not illustrated) in the form of a conti nuousstrip, and is progressively unwound, in use, off fr om thereel. The machine 1 comprises a conveyor6 foradvancingthe containers 2 to be labelled. The machine 1 comp risesa labelling module 7 which is peripherally arrangedrelative to the conveyor 6, for labelling the conta iners 2 being conveyed by the conveyor6.The conveyor6 is a carousel which rotates on at least one plane P foradvancing the containers 2. The plane P is indicate d inFigure 1 and is parallel or coincident with respect tothe plane ofFigure 1. The labelling module 7 isindicated in Figure 1. The module 7 comprises a feed roller8 forfeeding the web 4 oflabelling material. The module 7 comprises a cutting member 11 which isarranged downstream of the feed roller 8, with resp ect tothe feeding direction, for sequentially cutting the web4 thereby separating a sequence of labels 3 therefr om.The module 7 comprises a transferdrum 12 which isarranged downstream of the feed roller 8, with resp ect tosaid feeding direction. The transfer drum 12 is rot atableabout a rotation axis X in a first angular directio n ofrotation D, on at least said plane P, for receiving theweb 4 and applying the labels 3 on respective conta iners2 being conveyed by a conveyor 6. The feeding direc tionis defined by the angulardirection ofrotation of thefeed roller 8 and by the angular direction of rotat ion Dofthe drum 12. The transfer drum 12 comprises a plurality (Figures1 and 2, which are not limitative, show in particul arfive) of receiving sectors 13 each configured tocyclically receive and retain a label 3. When the l abel3 isstilljoined to the remaining partofthe web 4,itcananywaybeconsideredalreadyalabel3.Eachre ceivingsector 13 comprises a respective leading pad 13a fo rretaining a leading end portion 3a of the label 3 a nd atrailing pad 13b for retaining a trailing end porti on 3bof the label 3. Some leading end portions 3a and so metrailing end portions 3b are indicated in Figure 1.Thetransferdrum12cancompriseavacuumorsucti onsystem toenableeachpadtoretaintherespective portionof the label 3 by means of suction or vacuum. There fore,the transferdrum 12 can be a vacuum drum. The receiving sectors 13,the leading pads 13a andthe trailing pads 3b of the transfer drum 12 are sh own inFigure 1 and 2. The axis of rotation X and the direction of rotatio nD of the transfer drum 12 are indicated in Figure 1 .The cutting member 11 (illustrated in more detail i nfigure 3) is arranged radially adjacent to the tran sferdrum 12 and is configured forcutting the web 4 on thedrum 12 sequentially at the trailing pads 3b, there bysequentially separating the labels 3 from the web 4 .The cutting member11 comprises a blade element14and the transfer drum 12 comprises a plurality of s lots15. Each slot 15 is located at one respective trail ingpad 13b and is part of the respective receiving sec tor13. The cutting member 11 is configured for engaging th eblade 14 sequentially in the slots 15 to sequential ly cutthe web 4. The cutting member 11 comprises a cutting roller 11 1which is rotatable about a rotation axis Y in a sec ondangular direction of rotation E, at least on said p laneP. In particular, the axis X of rotation of the tra nsferdrum 12 and the axis of rotation Y of the cutting r oller111 are parallel to each other, and preferably vert ical.Thecuttingroller111carriessaidblade14,fore ngagingthe blade 14 sequentially in the slots 15 to sequen tiallycut the web 4. The rotation axis Y and the directio n ofrotation E ofthe cutting roller 111 are indicated in Figure 5. Each slot 15 is inclined, at least on said plane P,with respect to the radial direction R1 of the drum 12.The radial direction R1 of the drum 12 is the radia ldirection with respect to the axis X of rotation of thedrum 12. The radial direction R1 of the drum 12 is depicted in Figures3 and 7. Thanks to the cutting member 11 operating on the we b4 while the web 4is carried by the drum 12, and th ereforeoperating on the drum 12, the changeover can be fas terbecause the amount of operations to be done for ada ptingthe components dedicated to the cutting operation t o anew length ofthe label3 is significantly reduced or eliminated. Thanks to the slot15 being inclined,the positionof the blade 14 with respect to the web 4 during th ecutting is improved, to improve the precision of th ecutting operation. In particular, the inclination r educesthe amount of not needed (namely undesired) contactbetweentheblade14andtheweb4.Figure3shows anotherinstant, before cutting, which can be considered as afirst instant of the cutting operation. In the firs tinstant, the blade 14 is substantially facing the s lot 15without being yet in contact with the web 4 to be c ut.Figure 4 shows the instant of cutting, which can beconsidered as a second instant of the cutting opera tion.In the second instant, the blade 14 is facing the s lot 15and is in contact with the web 4 for cutting it. F igure5 showsa furtherinstant,which isaftercutting, which can be considered a third instant of the cuttingoperation. In the third instant, the blade 14 has a lreadycutthe web 4 and isdistanced from the slot15. Therefore, the changeover is made faster by means o fa solution improving the precision of cutting, than ks tothe inclined slot15. The blade 14 is offset,atleaston said plane P,withrespecttosaidrotationaxisY ofthecutting roller111. This allows to have the blade 14 being more ad aptedgeometrically to the inclination of the slot 15. B yarranging the blade 14 with the above-mentioned off set,thesecondinstantisbroughtforwardwithrespect tothecase in which the blade 14 would being arranged rad ially(namelyalongaradialdirectionR2ofthecutting roller111) with respect to the said rotation axis Y of th ecuttingroller111.TheradialdirectionR2ofthe cutting roller111 is the radialdirection with respectto the axis Y of rotation of the cutting roller 111. Inaddition, this offset permits that during the secon dinstant (namely during the effective cutting of the web4 as illustrated in figure 4), the blade 14 is substantiallyorthogonalto the web 4. The offset improves significantly the quality ofcutting, also in case the slot was not inclined, th anksto a better position of the blade 14 in the instant ofcutting. Therefore the offset of the blade 14, also witha not inclined slot, improves the precision of the cuttingoperation. In particular, the offset reduces the am ountofnotneeded(namelyundesired)contactbetweenth eblade14 andthe web4. An inclined slot15 allows for im provingthis effect.The inclination ofthe slot15 allows foradapting the slot 15 to the offset of the blade 14.As illustrated in the attached figures, due the offset,the blade 14 is also inclined with respect to a radialdirection R2 ofthe cutting roller 111 with an angle β. The angle β is comprised between the radialdirection R2 of the cutting roller 111 and an imagi naryline Z2 (indicated as a dotted line in Figures 3-5)passingthroughthe centerlineoftheblade 14. Th eblade14 can be considered a cutting edge or a cutting ti p.Each slot 15 is inclined with respect to the radialdirectionofthetransferdrum 12byanangle α,thevalueof which falls preferably within the range from 20° to 40°, more preferably between 25° and 35°. In this way theeffectofhaving an improved position ofthe blade 14with respect to the web 4 can be obtained minimizin g thelocalstress orstretching ofthe web 4.The value ofinclination of slot 15 with respect to radial direc tionof the transfer drum 12 can be forexample 30°. Th e angleα is comprised between the radial direction R1 of th edrum 12 and an imaginary line Z1 (indicated as a do ttedline in Figures 3-5) passing through the center lin e ofthe slot 15 and preferably being parallel to the la teralwalls of the slot15itself. In this way during the secondinstant the blade 14 and the slot 15 are engaged an d aresubstantially aligned one to the other,permitting thus to improve the cutting precision. Thecuttingmember11isconfiguredsothatthebla de14 while cutting is inclined by an angle µ (illustr atedin figure 4) with respect to the radial direction R 1 ofthe drum 12, at least on said plane P, to engage th e blade14itselfintheslot15.Theangleµiscomprised betweenthe radial direction R1 of the drum 12 and the imag inaryline Z2 (indicated as a dotted line in Figures 4) p assingthrough the center line of the blade 14 at the cutt inginstant.The angle µ can be nullorzero. Each trailing pad 13b comprises a holding surface 131b forsupporting the trailing end portion 3b of the label 3 and a frame surface 132b which is locateddownstream of the holding surface 131b, with respec t tosaid direction of rotation D and according to an observerwhich is not moving with the drum12. The slot 15 i s facedand opens on said frame surface 132b to receive the blade14. The frame surface 132b can be completely or par tiallyideal, in the sense that it can correspond complete ly orpartially to the opened front section of the slot 1 5. Thetrailing pad 13b comprisesalso a shouldersurface 133b, which is located downstream ofthe holding surface 131bandtheframesurface132b,withrespecttosaiddi rectionof rotation D and according to an observer which is notmoving with the drum 12. In particular, the holding surface 131b and the shoulder surface 133b aretransversal, in particular orthogonal, one to the o ther.In particular, each slot 15 is arranged at the fram esurface 132b comprised between the holding surface 131band the shoulder surface 133b of the trailing pad 1 3b.An example ofholding surface 131b,frame surface 132b and shouldersurface 133b are shown in Figure 7. Themodule7comprisesalsoaglueapplicationmemb er19 which operates downstream the cutting member 11, withrespect to said feeding direction, for applying glu esequentially on each leading end portion 3a and tra ilingend portion 3b, while the portion is supported by t herespective pad 13a or13b. The glue application member19 comprises a gluingroller 191 which is located radially tangent to thetransferdrum 12 forapplying the glue. Due to the structuralconformation ofthe trailingpad 13b, the frame surface 132b is located radially moreinternally than said holding surface 131b, with res pectto said radial direction R1 of the drum 12. In this way,the slot 15 opens at a radial height which allows t oprotect the walls of the slot 15 from the glue duri ng theapplication of glue on the trailing portion 3b of t helabel 3. The situation of application of glue is sh own inFigure 6,in which itcan be seen thatthe slot15 ispositionedinaprotectedposition,sothat,incas ethereisnolabel3,itiseliminated orreducedtheposs ibilitythat the slot 15 or the walls of the slot 15 gets d irty.Therefore,an improved cleanliness ofthe transfer drum 12 isobtained. Preferably, the cutting member 11 comprises astopping member 18 to press the web 4 against the h oldingsurface 131b during the cut. The stopping member 18 iscarried by the cutting roller 111. The stopping mem ber 18is indicated in Figures from 3 to 5. The stopping m ember18 can be flexible and / or elastic. The stopping mem ber 18can be made byan elastomericorelasticmaterial. The stopping member 18 is located downstream of theblade 14, with respect to said direction of rotatio n E ofthe cutting member11 and according to an observer whichis not moving with the cutting member 11. In this w ay itis avoided an interference between the stopping mem ber 18and a possible sliding ofthe web 4 on the drum 12 afterthe cutting, to improve thequality ofthe web4. I n fact,there may be the need of having such sliding to ada pt thepitch of the labels 3 to the pitch of the container s 2being conveyed bythe conveyor6. The use of a cutting member 11 operating on the dru m12 allows the feed roller 8 to be located radially adjacent to the transfer drum 12, to improve the compactnessofthe module 7. Each receiving sector 13 is removable andinterchangeable with a receiving sector 13 of a dif ferenttype and variable depending on the format of the la bels3 to be applied, so that the number of receiving se ctors13 can also be changed.Each trailing pad 13b with therespective slot 15 are removable and interchangeabl etogetherwith the respective receiving sector13. The labelling module 7 is configured forlabellingthe containers 2 by means of partial labels, each p artiallabel 3 being a label which, once completely applie d onthecontainers 2orattheendofthelabellingope ration,covers an angular sector of the external lateral su rfaceof the containers 2 thevalue ofwhich is lower tha n 360°,for example lower than 30°. This is in particular m adesimpler by the cutting member 11 operating on the d rum12, because a significantly reduced length of the l abel3 could make difficult the adaptation of the size o f thecomponentsdedicated to the cutting operation. The labelling module 7 is therefore globally configured for partial labelling with an improved precision and veryfastchangeover. The module 7 may be configured so that each label 3is completely applied on the respective container 2 bymeans of the respective receiving sector 13. The le adingpad 13a applies at least the leading end portion 3a ofthe label 3 and the trailing pad 13b applies at lea st thetrailing end portion 3b ofthe label3. The axis X is preferably parallelto axis Y.Theaxes X and Y are preferably parallel to the axis ofrotation ofthe carousel. The stopping member 18, for pressing the web, has atoothedprofile19alongtheverticaldirectionVp arallelto said rotation axis Y ofthe cutting roller111. Thevertical direction V is indicated in Figures 8, 9 a nd 10.The profile 19 comprises a plurality of teeth 191 w hichare intercalated with gaps 192. The profile 19 is schematicallyshown in Figures9 and 10. For each label, at least the trailing end portion 3 bis provided with at least one pattern P of adhesivematerial which is discontinuous along said verticaldirection V by comprising a plurality of first port ionsP1 and at least one second portion P2 which is loca tedbetween two first portions P1. Each first portion P 1 ismore adhesive than said second portion P2. The pattern P of adhesive material is discontinuousalong said vertical direction by comprising saidplurality of first portions P1 and a plurality of s econdportions P2. The second portions P2 are intercalate d withsaid first portions P1 along said direction. Each f irstportion P1 is more adhesive than each second portio n P2.Preferably, each second portion P2 is not adhesive.The profile 19 is complementary to said pattern P s othat said each tooth 191 presses on a respective se condportion P2 during the cut and each gap 192 is faced to arespectivefirstportionP1duringthecut.Thissi tuationis visible in Figure 10, which corresponds to the s ameinstant of Figure 4, which is the instant of cuttin g. InFigure 10, the web is shown along a transversal sec tion,so that the profile of the web is visible. In Figur e 10,the profile of the glue pattern is shown with firstportionsP1 and second portionsP2. The adhesive materialcan be glue. Also each leading end portion ofeach labelcan beprovided with a pattern P of adhesive material whic h canhave all the features described above with referenc e tothe pattern ofthe trailing end portion 3b. The whole surface of each label can be provided globally with a discontinuous pattern of adhesive material. Havingeachtooth191pressingonarespectiveseco ndportion P2 and each gap 192 facing a respective fir stportion P1 allows to reduce and preferably to elimi nateany problem of interference between the adhesive ma terialand the action of pressing the web which is exerted by the stopping member18. Consequently, the effect of improving the precisionof the cutting without any interference on a possib lesliding of the web, which effect is obtained by thestopping member 18, can be obtained also in case th e webis pre-adhesive web. With a pre-adhesive web it isintended a web which, during cutting, is already pr ovidedwith adhesive material for application of the label s onrespective containers. A pre-adhesive web allows anincrease in flexibility of the configuration of the gluepattern. In fact, by applying the glue on the web b eforethe feeding of the web, and maybe also before opera tionof the labelling module, a glue pattern with highercomplexity can be used. Thanks to the toothed prof ile19, the advantage of using the stopping member 18 i sobtained simultaneously with the increase in flexib ilitygiven by the use of a pre-adhesive web. A glue patt ernwith a higher complexity in turn allows to use thelabelling module with a wider range of format and / o rshapesofcontainers. Therefore,a rollfed labelling module is providedwhich is configured for applying labels with optima lprecision and is very flexible in terms of shapes a nd / orformatofcontainers. One advantage ofthe pre-adhesive web is thattheglue application member 19 can be dispensed with, t oimprove the cleanliness of the module 7. In fact, w ithoutapplying the glue in the module 7, there is less ri sk forthe components of the module, and above all for thetransfer drum, to become dirty. Therefore, having astopping member 18 with the toothed profile 19 allo ws theuse of a pre-adhesive web, if the web comprises thediscontinuous adhesive patterns, to increase thecleanliness of the module. On the other hand, the t oothedprofileofthestoppingmember18isinparticular adaptedtoanadhesivepatterwhichisdiscontinuousandth ereforemore complex. Therefore, the module can adapt bette r toan increase in complexity ofthe adhesive patterns andtherecanbeanincreaseincleanlinessand / orflex ibilityofthe module.
