- the self-adhesive label 250 has a lower self-adhesive support web 270 e.g. of paper which is coated on its rear surface with a layer 272 of pressure-sensitive adhesive and is releasably adhered to the release material 252.
- the support web 270 is coextensive with all of the self-adhesive label 250 apart from the free outer edge 274 of the folded sheet 258 which is intended to be releasably adhered to the release material 152. Accordingly, the free outer edge 274 is directly adhered to the release material 252 by the layer 264 of pressure-sensitive adhesive which has been applied over the release material/support web combination by the adhesive applicator 6 shown in Figure 1.
- the folded sheets have been applied in succession over the succession of support webs 270 but also ensuring that the portion (i.e the free outer edge) of the folded sheets which is intended to be releasably adhered to the release material is not disposed over a part of the support web but rather is disposed over the release material.
- the support web which is carried on the release material is larger than that which is present in the resultant label.
- the extra peripheral part of the support web is cut simultaneously with the cutting of the laminar material 254 the applied sheet 258 and the pressure-sensitive adhesive 264 and the combined waste web remnant is then removed.
- the support web 270 together with the rear layer of adhesive 272, is coextensive with the majority of the label 250.
- the advantage of this configuration is that the support web provides extra strength and rigidity to the resultant self-adhesive labels.
- the self-adhesive laminar material is coated with a pressure-sensitive adhesive.
- the laminer material is not uniformly coated with pressure-sensitive adhesive, but rather is provided with uncoated patches which, for example, coincide with part or all of the applied folded sheets.
- the self-adhesion is provided not by a layer of pressure-sensitive adhesive but by a heat-sealable material such as a hot-melt adhesive, lacquer or plastics material which is subsequently heat sealed.

Description
- The present invention relates to a method or producing labels and in particular to a method of producing a succession of self-adhesive labels on a length of release material. The present invention also relates to a self-adhesive label.
- In the packaging field there is a great demand for high quality pre-printed labels for labelling containers of various types. In order to facilitate the packaging and labelling of containers at a fast rate it is generally required that the labels to be attached to the containers be made available in a form in which they are easy to handle and easy to transfer onto the containers for which they are intended. In one convenient arrangement the labels are self-adhesive labels which are carried in series on a web of release material which is wound into a reel. The Applicant's earlier GB-A-2199010 discloses a method and apparatus for producing labels in which self-adhesive labels are carried directly on a release material.

- Referring to Figure 1, there is shown an apparatus for producing labels in accordance with the method of the present invention. A web of
release material 2 is fed out from a reel 4 thereof past anadhesive applicator 6 which is adapted to deposit a layer of pressure-sensitive adhesive (not shown) over the upper surface of therelease material 2. Therelease material 2 typically comprises waxed or siliconized paper. The adhesive may be extruded in a hot melt form and may be extruded either as a continuous uniform layer or in the form of a row of extruded beads. The adhesive-coatedrelease material 2 then passes to a folded sheet applying station 8 at which a succession of individual foldedsheets 10 are applied to the layer of pressure-sensitive adhesive so as to adhere the foldedsheets 10 to therelease material 2. The foldedsheets 10 are described in greater detail below. The succession of foldedsheets 10 carried on therelease material 2 is then passed to a laminarmaterial applying station 12 at which a self-adhesive laminar material 14, which is fed out from areel 13 thereof, is applied to the succession of foldedsheets 10 on therelease material 2. The self-adhesive laminar material 14 comprises a layer of plastics material, preferably transparent polyester or polyethylene, coated on one side with a pressure-sensitive adhesive. Thelaminar material 14 is adhered by the downwardly-directed self-adhesive surface thereof over the succession of foldedsheets 10. The laminar material - coated assembly then passes to a die-cutting station 15 at which the self-adhesive labels 16, which will be described in greater detail below, are formed by cutting through thelaminar material 14, the foldedsheets 10, and the pressure-sensitive adhesive as far as therelease material 2. The die-cutting is carried out by a pair of die-cutting rollers 17. At the die-cutting station 15, awaste web remnant 18, consisting of waste portions of thelaminar material 14, of the foldedsheets 10 and of the pressure-sensitive adhesive which surround the self-adhesive labels 16, is removed from therelease material 2 and wound up into areel 20 for subsequent disposal. The succession of self-adhesive labels 16 on therelease material 2 is then wound up into areel 22 which subsequently can be mounted in an automatic labelling machine (not shown) for automatic application of the labels to containers to be labelled. - Figure 2 shows a first embodiment of a folded
sheet 10. The foldedsheet 10 comprises a rectangular longitudinal strip which is divided into a series of panels by a plurality of transverse fold lines. Anupper panel 22 constitutes one end panel of the strip and alower panel 24 is connected thereto by a foldededge 26 of the foldedsheet 10. A number ofadditional panels 28 are folded between theupper panel 22 and thelower panel 24. It will be seen that theupper panel 22 completely covers and extends past thelower panel 24 so as to have a rearwardly-directedsurface 30 which is adjacent the rearwardly-directedsurface 32 of thelower panel 24. Accordingly, the rear surface of the folded sheet comprises the rearwardly directedsurfaces upper panel 22 is provided with a row of holes (not shown) extending therethrough, which row is adjacent to the foldededge 26. The holes expose corresponding parts of thelower panel 24. - Figure 3 shows a second embodiment of a folded sheet 10' which is an inverted form of the folded
sheet 10 of the first embodiment illustrated in Figure 2. Thus thelower panel 34 has a rearwardly directedsurface 36 which defines the entire rearwardly directed surface of the folded sheet 10'. Theupper panel 38 is connected to thelower panel 34 by a foldededge 40. A number ofadditional panels 42 are disposed between theupper panel 38 and thelower panel 34. The upper surface of the folded sheet 10' consists of theupper surface 44 of theupper panel 38 and theupper surface 46 of that portion of thelower panel 34 which is not covered by theupper panel 38 or theadditional panels 42. Theupper panel 38 is, in a manner similar to that of theupper panel 22 of the first embodiment shown in Figure 2, provided with a row of holes (not shown) extending therethrough adjacent the foldededge 40, which holes expose respective parts of thelower panel 34. - Each of the folded
sheets 10, 10' of Figures 2 and 3 is printed with information relating to the container to be labelled. Preferably, each sheet is lithographically printed but alternative printing methods include letterpress, flexographic or laser printing. Typically, each foldedsheet 10, 10' is composed of paper. - The following Figures 4 to 6 illustrate the manufacture and use of a self-
adhesive label 16 employing a foldedsheet 10 in accordance with the first embodiment thereof shown in Figure 2 but it will readily be understood by the man skilled in the art how to manufacture self-adhesive labels incorporating the folded sheets 10' shown in Figure 3. - Figure 4 shows a folded
sheet 10 which is adhered to therelease material 2 by alayer 48 of pressure-sensitive adhesive, the assembly being prior to the laminarmaterial applying station 12. It will be seen that a row ofholes 50 extending through theupper panel 22 exposescorresponding parts 52 of thelower panel 24 thereunder. The row ofholes 50 is adjacent the foldededge 26 between the upper andlower panels surface sheet 10 is adhered by thelayer 48 of pressure-sensitive adhesive to therelease material 2. - The assembly shown in Figure 4 is then passed to the laminar
material applying station 12 and then to the die-cutting station 15 and Figure 5 shows the resultant assembly after the application of thelaminar material 14 and die-cutting of the combined assembly to form the self-adhesive labels 16 on therelease material 2. From Figure 5 it will be seen that thelaminar material 14 extends over the whole of the upper surface of the printedsheet 10 and is adhered thereto by the self-adhesive surface thereof. In particular, thelaminar material 14 extends over theholes 50 thereby to form corresponding self-adhesive exposedportions 54 of thelaminar material 14 which are adhered by the respective self-adhesive surfaces to thecorresponding parts 52 of thelower panel 24. During the die-cutting step, the foldedsheet 10 has been cut around its periphery so that the resultant self-adhesive label 16 is accurately positioned and aligned on the web ofrelease material 2. This accuracy is important when thelabel 16 is subsequently to be applied to a container to be labelled by an automatic high speed labelling apparatus. In particular, in the cutting step the foldededge 26 between the upper andlower panels outer edge 56 of theupper panel 22. It will be understood that the self-adhesive label 16 is maintained in its closed configuration by the adhesion of the exposedportions 54 of thelaminar material 14 to thelower panel 24. - Figure 6 shows the
label 16 of Figure 5 when adhered to acontainer 58. As is shown in Figure 6, when it is desired to open thelabel 16 and access theconcealed panels 28, a user pulls the freeouter edge 56 of theupper panel 22 away from thelower panel 24 thereby to release the exposedportions 54 of the self-adhesivelaminar material 14 from thelower panel 24. A hingedportion 60 of theupper panel 22, which is not directly adhered to thecontainer 58, is then folded back to reveal the previously hiddeninner surface 62 thereof and theadditional panels 28 of thelabel 16 can then be unfolded as shown in Figure 6. If desired, one or more weakened tear lines may be provided on theadditional panels 28 so that one or more of thosepanels 28 can be torn off from thelabel 16 which is adhered to the container. When a user has finished reading the information on thelabel 16, he can re-close thelabel 16 by folding the hingedportion 60 of theupper panel 22 back over thelower panel 24 and re-adhere the exposedportions 54 of self-adhesive laminar material to thelower panel 24. - Figure 7 shows a self-
adhesive label 70 in accordance with a further embodiment of the present invention. The self-adhesive label 70 comprises a foldedsheet 72 which is similar in construction to the folded sheet 10' shown in Figure 3. The foldedsheet 72 comprises a rectangular longitudinal strip which is divided into a series of panels by a plurality of transverse fold lines. Alower panel 74 has a rearwardly directedsurface 76 which defines the entire rearwardly directed surface of the foldedsheet 72. Theupper panel 78 is connected to thelower panel 74 by a foldededge 80 andadditional panel 82 is disposed between theupper panel 78 and thelower panel 74. The foldedsheet 72 is lithographically printed. The rearwardly directedsurface 76 of the foldedsheet 72 is adhered to a web ofrelease material 84 by alayer 86 of pressure-sensitive adhesive. The foldedsheet 72 is entirely covered by a self-adhesivelaminar material 88 which is adhered by the self-adhesive surface thereof to the upper surface of the foldedsheet 72. Alongitudinal end 90 of thelaminar material 88 extends past the foldededge 80 and is adhered to therelease material 84 by a combination of the self-adhesive surface thereof and thelayer 86 of adhesive. Thus the applied folded sheet is shorter than the laminar material. Typically, the adheredend 90 of the laminar material has a width of about 5 mm. A line ofperforations 92 extends across thelaminar material 88 in the vicinity of theupper panel 78 of the foldedsheet 72. - When it is desired to access the concealed surfaces of the folded
sheet 72, theperforation line 92 is torn thereby to permit theupper panel 78 and theadditional panel 82 attached thereto to be hinged away from thelower panel 74. - The label of Figure 7 may be made by substantially the same method as that described with reference to Figure 1. As will be clear, the folded sheet is not provided with a row of holes as in the embodiment of Figures 4 to 6 and the folded
edge 80 is not cut away from the foldedsheet 72. Instead, the leading edge of the resultant self-adhesive label 70 consists of aportion 90 of thelaminar material 88 which is adhered to therelease material 84 by the layer ofadhesive 86. At the die-cuttingstation 15, the die-cutting rollers are adapted to cut not only the self-adhesive labels but also if desired the die-cuttingrollers 17 may cut theperforation line 92 in the laminar material either in the same or in a separate die-cutting step. The die-cutting rollers may be adapted to cut theperforation line 92 additionally through theupper panel 78 of the foldedsheet 72. The applied folded sheet may have the configuration shown in Figure 2 when the folded sheet is also provided with the perforation line. - Figure 8 shows a lithographically-printed folded
sheet 100 which is employed in the manufacture of a self-adhesive label in accordance with the third embodiment of the present invention. The foldedsheet 100 comprises a rectangular longitudinal strip which is divided into anupper panel 102 and alower panel 104 which is connected to theupper panel 102 by a foldededge 106 of the foldedsheet 100. Although not illustrated, a number of additional panels may be disposed between theupper panel 102 and thelower panel 104. When present, the additional panels are connected to one or both of the upper andlower panels upper panel 102 completely covers and extends past thelower panel 104 so as to have a rearwardly-directedsurface 108 which is adjacent to the rearwardly-directedsurface 110 of thelower panel 104. Accordingly, the rear surface of the foldedsheet 100 comprises the rearwardly-directedsurfaces upper panel 102 is lithographically printed as are the opposedinner surfaces lower panels sheet 100 which has been adhered to a length ofrelease material 118 by alayer 120 of pressure-sensitive adhesive, prior to the laminarmacerial applying station 12. The rearwardly-directedsurfaces sheet 100 are adhered by thelayer 120 of pressure-sensitive adhesive to therelease material 118. - The assembly shown in Figure 9 is then passed to the laminar
material applying station 12 and then to the die-cuttingstation 15 and Figure 10 shows the resultant assembly after the application of the laminar material and die-cutting of the combined assembly to form the self-adhesive labels on the release material. The laminar material comprises a transparent plastics material, such as polyester or polyethylene. From Figure 10 it will be seen that a cut portion of the laminar material 112 constitutes the upper surface of the resultant self-adhesive label 124. During the die-cutting step, the foldedsheet 100 has had the longitudinal edges thereof cut away and also the free outer edge of the extending part of theupper panel 102 has also been cut away. Thelaminar material 122 is coincident with the cutlongitudinal edges sheet 100 and is also coincident with the cuttransverse edge 130 of the foldedsheet 100. Thelaminar material 122 extends beyond the foldededge 106 of the foldedsheet 100 to form anend flap 132 thereof which is adhered by a combination of its self-adhesive surface and thelayer 120 of pressure-sensitive adhesive to therelease material 118. The self-adhesive label 124 is maintained in its closed configuration by the adhesion of the rearwardly-directedsurface 108 of theupper panel 102 to therelease material 118. - Figure 11 shows the
label 124 of Figure 10 when adhered to a container 134. The rearwardly-directed surface of thelabel 124 consists of that portion of the layer of adhesive 120 which is adhered to the rearwardly directedsurfaces lower sheets flap 132 of thelaminar material 122. When thelabel 124 is removed from therelease material 118, the portion of the layer ofadhesive 120 is stripped off therewith and that portion of the layer ofadhesive 120 adheres thelabel 124 to the container 134. When it is desired to open thelabel 124 and access the concealed surfaces of the upper andlower panels outer edge 136 of theupper panel 102 away from thelower panel 104. The freeouter edge 136 and the part of the layer of pressure-sensitive adhesive 120 which is adhered directly to the rearwardly directedsurface 108 of theupper panel 102 are stripped off from the container as a result of preferential adhesion of the adhesive to the rearwardly-directedsurface 108 of the upper panel. Theportion 138 of theadhesive layer 120 remains adhered to theupper panel 102 as is shown in Figure 11. When a user has finished reading the information on thelabel 124, he can re-close thelabel 124 by folding theupper panel 102 back over thelower panel 104 and by re-adhering theadhesive part 138 to the container 134. - In the embodiment of Figures 8 to 11, the folded
edge 106 is protected from being accidentally caught and pulled away from the container to which it is adhered by thelaminar material 122 which extends over the foldededge 106 to form theflap 132. Thus theresultant label 124 is reliably and securely adhered over its whole surface to the container 134. As is shown in Figures 10 and 11, in the die-cutting step the corners of the label are preferably cut rounded. This is carried out not only for aesthetic purposes but also to assist a user in opening the resultant label and also to reduce the chances of the corners of the label being bent or caught by extraneous objects. - If desired, the layer of pressure-
sensitive adhesive 120 may be applied to the release material as a non-continuous layer whereby a corner of the rearwardly directedsurface 108 of theouter edge 136 of theupper panel 102 is not coated with adhesive - this assists in a user being able to pull theupper panel 102 away from thelower panel 104 in order to open the label. - Figure 12 shows a
label 150 in accordance with a fourth embodiment of the present invention when carried on a length ofrelease material 152. This embodiment is different from that illustrated in Figure 8 to 11 in that the self-adhesivelaminar material 154 extends substantially past the foldededge 156 of the foldedsheet 158 thereby to define alabel portion 160 which is adjacent the foldedsheet 158. The self-adhesive laminar material is of transparent plastics such as polyester or polyethylene and has animage 162 printed on the rearwardly-directedsurface 164 thereof, which image is disposed in the portion of the label adjacent to the folded sheet. In the manufacture of the labels, thelaminar material 14 shown in Figure 1 would consist of a length of transparent plastics material having a succession ofimages 162 printed on itslower surface 164. Thelaminar material 14 would be adhered over the assembly of folded sheets/pressure-sensitive adhesive/release material with theimage 162 on the transparent laminar material being in registration adjacent a respective foldedsheet 158. In the die-cutting step, the die-cutting would be carried out so that eachlabel 150 includes a respective printedimage 162 on the transparentlaminar material 154 and a respective foldedsheet 158 adjacent thereto. - Figure 13 shows a
label 250 in accordance with a fifth embodiment of the present invention when carried on the length ofrelease material 252, thelabel 250 being a modification of the label of Figure 12. This embodiment is different from that illustrated in Figure 12 in that prior to the application of pressure-sensitive adhesive 264 to the release material, the release material is provided thereover with a succession of support webs, each of which comprises a layer of paper or other material which is coated on its rear surface with a pressure-sensitive adhesive and is carried on the release material. These support webs have been produced by die-cutting pressure-sensitive stock, comprising the paper or other material releasably adhered on the release paper, with the waste remnant having been removed. Thus in the apparatus of Figure 1 the reel 4 comprises therelease material 2 with a succession of self-adhesive support webs thereon. Referring to Figure 13 again, the self-adhesive label 250 has a lower self-adhesive support web 270 e.g. of paper which is coated on its rear surface with alayer 272 of pressure-sensitive adhesive and is releasably adhered to therelease material 252. Thesupport web 270 is coextensive with all of the self-adhesive label 250 apart from the freeouter edge 274 of the foldedsheet 258 which is intended to be releasably adhered to therelease material 152. Accordingly, the freeouter edge 274 is directly adhered to therelease material 252 by thelayer 264 of pressure-sensitive adhesive which has been applied over the release material/support web combination by theadhesive applicator 6 shown in Figure 1. - In the manufacture of the label of Figure 13, the folded sheets have been applied in succession over the succession of
support webs 270 but also ensuring that the portion (i.e the free outer edge) of the folded sheets which is intended to be releasably adhered to the release material is not disposed over a part of the support web but rather is disposed over the release material. Initially, the support web which is carried on the release material is larger than that which is present in the resultant label. During the die-cutting step, the extra peripheral part of the support web is cut simultaneously with the cutting of thelaminar material 254 the appliedsheet 258 and the pressure-sensitive adhesive 264 and the combined waste web remnant is then removed. Thus in each resultant label thesupport web 270, together with the rear layer ofadhesive 272, is coextensive with the majority of thelabel 250. The advantage of this configuration is that the support web provides extra strength and rigidity to the resultant self-adhesive labels. - In the illustrated embodiments, the self-adhesive laminar material is coated with a pressure-sensitive adhesive. However, in alternative embodiments, the laminer material is not uniformly coated with pressure-sensitive adhesive, but rather is provided with uncoated patches which, for example, coincide with part or all of the applied folded sheets. In further alternative embodiments, the self-adhesion is provided not by a layer of pressure-sensitive adhesive but by a heat-sealable material such as a hot-melt adhesive, lacquer or plastics material which is subsequently heat sealed.
