BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the art of pressure sensitive labels, method and apparatus for making and using same, and label printing and applying machines.

2. Brief Description of the Prior Arts Various U.S. Pat. Nos. 1,642,387, 2,259,358, 2,275,064, 2,502,257, 2,516,487, 2,620,205, 2,656,063, 3,051,353, 3,265,553, 3,343,485, 3,440,123, 3,501,365, 3,551,251, and 3,611,929 and British Pat. No. 1,057,126, Feb. 1, 1967 are made of record.

SUMMARY OF THE INVENTION Briefly stated, the method comprises providing label material on a web of supporting material, pressure sensitive adhesive releasably securing the label material to the supporting, material, severing only the label material transversely with respect to the web of supporting material to provide a plurality of labels carried by the web of supporting material, and simultaneously cutting both the label material and the supporting material at spaced apart intervals to provide at least one cut into the label to render the label more difficult to remove when applied to merchandise and to provide at least one cut in the supporting material to facilitate advancing the web. The cuts are preferably formed into spaced apart groups of cuts in the supporting material web and in the label material, each group having a first cut extending longitudinally of the web and a second cut extending transversely of the web and spaced from the end of the first cut to provide a frangible portion in both the supporting material web and in the label material, so that when an advancing tooth of a driver engages the web of at least one group of cuts in the web the tooth will cause the frangible portion of the web to be severed so that the tooth can engage the web at the second cut to advance the composite web. In another embodiment, the method comprises providing labels on a web of supporting material, pressure sensitive adhesive releasably securing the labels to the supporting material, the supporting material having straight side edges, and making a plurality of spaced apart cuts extending through both the supporting material and at least partially through the label material at the marginal edges of the composite web, the part of the cuts in the label material rendering the label more difficult to remove when applied to merchandise and the part of the cuts in the supporting material facilitating advance of I the web by engagement of a tooth of a driver. In these embodiments, the method is practiced on a wide web and, after the cuts are made, the composite web is slit longitudinally in a particular relationship to the groups of cuts to provide a plurality of composite webs of labels, each having a plurality of groups of cuts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the embodiment of FIGS. 1 through 8,

and in particular to FIGS. 2, 3 and 4, there is shown a composite web 30 of label material 31 releasably adhered to and carried by supporting or backing material 32. The label material 31 is cut transversely by trans-- verse cuts 33 extending all the way across the web 31 of label material to the side edges 34 and 35 of the composite web 30, as best shown in FIGS. 2 and 4. The cuts 33 known as butt cuts" separate the web 31 of label material into a series of end-to-end labels 36. The side edges of the label material as well as the supporting material are straight and the label material is coextensive with the supporting material.

The underside of the web 31 of label material has a coating of pressure sensitive adhesive 37 which adheres strongly to the web 31 of label material. The adhesive is shown to extend across the entire underside of the label material even to the side edges 34 and 35 of the web 30. The web 32 of supporting material carries a thin film or coating (not shown) which allows the labels to be peeled from the web 32 of supporting material.

Groups 38 of cuts are provided at equally spaced apart intervals along the length of the composite web 30. Each group 38 of cuts is shown to extend through the supporting material as well as through the label material. Each group 38 of cuts is shown to be made in a generally l-shaped configuration comprised of a straight longitudinal or vertical bar cut 39S in the supporting material and an aligned straight longitudinal or vertical bar cut 39L in the label material. Spaced from the one ends of the vertical bar cuts 39S and 39L are straight transverse of horizontal bar cuts 408 in the supporting material and 40L in the label material. Spaced from the other ends of the

vertical bar cuts

398 and 39L are aligned straight transverse or horizontal bar cuts 418 in the supporting material and straight transverse or horizontal bar cuts 41L in the label material.

The part of the web 32 between the one end of the cut 398 and the cut 40S provides a frangible portion 43S and the part of the web 32 between the other end of the cut 39S and the cut 418 provides a frangible portion 428. In like manner, the part of the label material between the end of the cut 39L and the cut 40L provides a frangible portion 43L and the part between the other end of the cut 39L and the cut 41L provides a frangible portion 42L. As a variation of the illustrated groups 38 of cuts, the cuts 40L and 405 can be omitted in which event the cut 398 will be extended by tearing as the tooth 48 engages the web 32 at the cut 39S; this would result in groups of cuts each having a generally T- shaped configuration as shown in FIG. 25.

With reference now to FIG. 1, the composite web 30 is shown to be in the form of a roll which can be wound on a core 44, as desired. The core 44 can receive a shaft 45 about which the roll is free to rotate in the direction of arrow 46. The roll is wound in such a manner that the label material is on the outside in overlying relationship with respect to the web 32 of supporting material.

A toothed driver generally indicated at 47 is shown to be in the form of a driven sprocket having teeth 48 disposed in a plane at equally spaced apart angular positions around the circumference of the driver 47. The driver 47 is used to advance the composite web first to a printing zone at which a printer 48' and a platen 49 are disposed. A relatively sharp peel edge 50 is diagrammatically illustrated as being disposed at the terminal end of the platen. The web of supporting material 32 is drawn around the peel edge 50 by the toothed driver 47. The edge 50 causes the supporting material 32 to make an abrupt change in direction, thereby effecting delamination or peeling of the supporting material 32 from one label 36 at a time as the web of supporting material is concomitantly advanced by the toothed driver 47. An applicator 51 is positioned beyond the peel edge 50 and on the same side of the label as the printer 48'. The applicator 51 is shown to take the form of a conventional applicator roll, however, other types of applicators such as a plunger, a presser foot, or the like can be used, if desired. The composite web 30 approaches the printing and applying zones generally in the direction of an arrow 52, and after passing around the peel edge 50 the web 32 of supporting material advances generally in the direction of arrow 53 and passes partially around a guide roller or shaft 54. From the guide roller 54, the web 32 passes partially around the toothed driver 47. From there the web 32 passes partially around a guide roller or shaft 55 and from there the web 32 is guided by means of guides in the direction of the arrow 56. The toothed driver 47 is driven stepwise by a pawl and ratchet mechanism so that upon operation of this mechanism the composite web 30 is advanced through the appropriate distance so that the labels can be printed at one or more stages and so that a label is brought to the applying zone at which the applicator 51 is effective to apply the dispensed label to merchandise M. The web 32 passes between the outer surface of the toothed driver 47 and a guide or hold down plate 57 as shown in FIGS. 1, 6, 7 and '8. As the driver 47 rotates, successive teeth engage successive groups of cuts in the web 32.. As a tooth engages the web 32 at a longitudinal cut 395 frangible portions 42S and 438 are severed as by tearing to provide a feed hole 58. The feed hole 58 thus formed receives the tooth 48 and deflects flaps 59 and As best seen in FIG. 7, the guide 57 has a concave section 60 with a groove 61 in the same plane as the teeth 48. The transversely extending flaps 59 and 59' are shown to enter the groove 61 when the tooth 48 is in the feed hole 58. As best shown in FIGS. 6 and 7, each tooth 48 terminates at a sharp pointed end 62 which serves to facilitate severing of the frangible portions 42S and 438. The guide 57 has

flanges

63 and 64 which are in guiding engagement with edges 65 and 66 of the web 32.

The spacing of the teeth 48 around the periphery of the driver 47 is the same as the spacing of the groups 38 of cuts lengthwise of the composite web 30. The teeth 48 are identical and only one is shown in detail in side elevation in FIG. 8. In FIG. 8, the tooth 48 is shown to have involute contoured faces 67 and 68 which enable it to readily make a feed hole 58 in the web 32 which has passed partially around guide rollers 54 and to move out of the feed hole easily just before the web 32 passes partially around the roller 55. As shown in FIG. 8 the face 67 of the tooth 48 is shown to be in driving engagement with the leading edge 69 of the feed hole 58. The face 68 of the tooth 48 is shown to be slightly spaced from trailing edge 70 of the feed hole.

The groups of cuts 38 do not substantially affect the v integrity of the web 32 until feed holes are made by the teeth of the driver 47 or the like. There are no flaps or lids as in the prior art which result in weakening of the web 32 at the delaminating zone where the strength of the web is particularly important. Also there are no flaps to result in possible interference with the feeding of the web. In addition, the types of cuts forming the group 38 make it feasible for the composite web 30 to be fed in either direction with equal efficacy. With the prior art US. Pat. No. 3,501,365 to E. C. Marshall the composite web can be fed in only one direction using the cut edge. The invention is not limited to providing a group 38 or cuts across the marginal ends of each label; while this is the preferred arrangement, the group 38 of cuts can extend across the marginal end of every other label, or the groups 38 of cuts can be disposed within the periphery of each label or of every other label, is desired.

The embodiment of the composite web 30A shown in FIG. 9 is identical to the embodiment of the composite web 30 and is used in the same manner, except the composite web 30A has at least one short straight transverse cut 80 in each marginal edge of each label 36a. There are, however, no cuts in the marginal edge of web 32a of supporting material. The cuts 80 serve further to prevent switching of the labels 36a once they have been applied to merchandise.

The embodiment of the composite web 303 shown in FIG. is identical to the embodiment of the composite web 30A, except that the individual cuts of each group of longitudinally spaced apart groups 38b of cuts intersect. Specifically, the composite web 30B has a web 31b of label material and a web 32b of supporting material. The web 32b of supporting material has longitudinal or vertical bar cuts 905 which extend to transverse or horizontal bar cuts 918 and 928. The cuts 908, 918 and 92S define transversely extending flaps or lids 93 and 94. The composite web 30B can be delaminated and advanced by the same apparatus as shown in FIGS. 1 and 6 through 8. The cuts 915 and 92S provide feed holes that the teeth 48 of the toothed driver can enter as the driver 47 rotates.

A longitudinal or vertical bar cut 90L is made in the label material simultaneously with the making of the cut 908, and therefore these two cuts are in alignment.

. Cuts 91L and 92L are made in the label material simultaneously with the making of the cuts 918 and 92S, and therefore the cuts 91L and 92L are in alignment with respective cuts 915 and 928. The cuts 90L, 91L and 921. in the label material provide a generally T-shaped cut in each marginal end of each label 368 and hence tend to prevent switching of the labels once they have been applied to merchandise.

Referring to the embodiment of FIGS. 11 through 14, there is shown a composite web 30C comprised of a web of label material 310. Transverse equally spaced apart cuts extend entirely across the web 31c of label material at equally spaced intervals to provide labels 36c. Spaced apart short transverse cuts 1008 are r effect advance of the composite web 30C As teeth 48c engage the web 320 they effect deflection of flaps 101 facilitated by a pair of adjacent cuts 1005, one cut 1008 of each pair of cuts provides a drive face 102 at the place where the leading edge of the respective tooth 48c engages it.

Referring to the embodiment of FIGS. 15, 16 and 17, composite web 30D is identical to the composite web 30C in the embodiment of FIGS. 11 through 14 except that both the label material 31d and the web 32d of supporting material are provided with a group of at least three spaced apart cuts rather than a pair of spaced apart cuts. Specifically, transverse equally spaced apart groups of cuts 1105 are made in the web 32d of supporting material. Short transverse cuts llOL are disposed in each marginal side edge of the web 31d of label material in alignment with respective cuts 1108 in the supporting material. Each cut 1108 in the supporting material and the associated cut L in the label material are preferably made simultaneously with the same cutting blade. With reference to FIG. 17 a toothed driver 47d is shown to have a substantially smaller diameter than the toothed driver 470 (FIG. 14). The composite web 30D is preferably made with at least three cuts in that the toothed driver 47d has a small diameter and in that it is easier for the flaps 111 formed by the cuts 1108 to be deflected as the web 320' passes around the toothed driver 47d. Adjacent flaps 111 of a group of flaps extend outwardly and make an acute angle with respect to each other. The labels are indicated at 36a. r

Referring now to FIG. 18, there is shown a composite web 30E having a web of label material 31e and a web 32e' of supporting material. The web 32a is engaged by a toothed driver 47e' having triangularly shaped teeth 48e. Transverse equally spaced apart cuts 33e' extend entirely across the web 312' of label material at equally spaced apart intervals to provide labels 36a. Spaced apart short transverse cuts 1205 are formed in both marginal side edges of the web 32e'. Short transverse cuts L are formed in each marginal side edge of the label material 31c in alignment with respective cuts .1203 in the web 32e'. Each cut 1208 in the supporting material and the associated cut 120L in the label material is preferably made simultaneously with the same cutting blade. The toothed driver 472' is shown to be rotating in driving engagement with the web 32a of supporting material to effect advance of the composite web 30E. The teeth 48a effect deflection of flaps 112 and engage drive faces 113 at one side of each cut 1208.

Referring to FIGS. 19 and 20 there is shown a wide composite web 30AW, for example, for making the composite web 30A. The web 30AW is shown being advanced in the direction of arrow A. The composite web 30AW is comprised of the label material 31a adhesively secured to a web 32a of supporting material passing between cutter roll having a plurality of knives 131 and a cooperating backup roll 132. The knives 131 travel at the same linear speed as the speed of the web 30AW and serve to cut through the web 31a of label material across its entire width to make the cuts 33. A cutter roll 133 and a backup roll 134 are disposed beyond the cutter roll 130 and the backup roll 132. As the composite web 30AW passes between the cutter roll 133 and the backup roll 134, knife blades or

knives

135, 136 and 137 make transverse cuts 80 in only the web 31a of label material. Thereafter two lines of printing P are printed on the web 31a by print drum 138 and a cooperating platen roll 139. From there the composite web AW passes between a cutter roll 140 and a cooperating platen roll 141. The cutter roll 140 has spaced apart groups 38K of cutter blades or knives. Each group 38K of cutter knives comprises a longitudinal or vertical bar cut knife 39K, tranverse or horizontal bar cut knife 40K and transverse or horizontal bar cut knife 41K. Each group 38K of knives makes on group of cuts 38a in the composite web 30A. As best shown in FIG. 20, the

knives

39K, 40K and 41K cooperate with the platen roll 141 with zero clearance. Accordingly, each of the

knives

39K, 40K and 41K cut entirely through the web 31a and the web 32a, whereas

knives

131 and 135, 136 and 137 of the respective cutter rolls and 133 cut entirely through the label material 31a but not into the web 32a.

After passing between the cutter roll 140 and the platen 141 the composite web 30AW is slit into a plurality of composite webs 30A by cooperating slitter elements 142 and 143. Each composite web 30A can not be formed into rolls.

Referring not to FIGS. 21 and 22, there is shown a composite web 30DW traveling in the direction of arrow A1. The web 30DW passes between cutter roll and platen roll 151. The cutter roll has spaced apart cutter blades or knives 152 for making cuts 33d at equally spaced apart intervals along the length of the web 30DW. Spaced beyond the cutter roll 150 and the platen 151 are cutter rolls 153 and a cooperating platen roll 154. The cutter roll 153 has groups of knives 110K for making cuts 110L in the label material and for simultaneously making cuts 1108 in the supporting material. Spaced beyond the cutter roll 153 and the platen roll 154 are cooperating

slitter elements

155 and 156 which slit the web 30DW into a plurality of composite webs 30D, and these composite webs 30D can be formed into rolls. As evident from FIG. 22, a cutter blade 152 cuts only through the label material 31d and not into the web 32d of supporting material. However, the cutter blades or knives 110K are set to zero clearance with respect to the platen roll 154 so that each cut 1108 and its associated cut 110L are made simultaneously by the respective knife 110K.

Referring to the embodiment of FIG. 23 and FIG. 24, there is shown a composite web 30E which is identical to the composite web 30A (FIG. 9), except that the composite web 30E has a group 38e of cuts illustrated as being arranged in a generally T-shaped configuration. The group 38e of cuts is shown to be comprised of a straight longitudinal or vertical bar cut 160S in supporting material 161 and an aligned straight longitudinal or vertical bar cut 160L in label material 162. Spaced from the one ends of the longitudinal cuts 1608 and 160L are horizontal or transverse bar cuts 1635 in supporting

material

161 and 163L in label material 162. The part of the supporting material 161 between the one end of the cut 1608 and the cut 1635 provides a frangible portion 1648 and the part of the label material 162 between one end of the cut 1601. and the cut 163L provides a frangible portion 1641,. The label material 162 is provided with transverse cuts 33e extending all the way across the web 162 of label material as shown in FIG. 23. The cuts 33e separate the label material 162 into labels 36e. The composite web 30E differs from the embodiment of FIG. 9 in that it is shown to have a pair of shortstraight transverse cuts 165 in each marginal edge of the labels 36e. There are, however, no cuts in the marginal edge of the supporting material 161. The cuts 165 serve to prevent switching of the labels 36e when applied to merchandise.

FIG. 24 shows a fragmentary portion of a toothed driver 47e having a tooth 166 of a generally triangular shape but having a drive face 167 curved like the drive face 67 of of driver 47. As a tooth 166 initially engages the supporting material 161, it will cause rupture of the frangible portion 1645 and the tooth 166 will cause triangular-shaped flaps 1688 to be formed as best shown in FIG. 24. One tooth 166 is shown to be in driving engagement with the web of supporting material 161 and the other tooth 166 is shown to be out of engagement with the supporting material 161.

The embodiment of FIG. 25 is like the embodiment of FIG. 23 in providing generally T-shaped groups 38f of cuts, except that with the composite web 30F, longitudinal or vertical bar cuts 1698 in supporting material 170 meet transverse or horizontal bar cuts 1718. There are aligned longitudinal or vertical bar cuts 169L and transverse or horizontal bar cuts 171L in the label material 173. Transverse cuts 33f separate the label material 173 into labels 36f. Composite web 30F has short straight transverse cuts 174 in each marginal side edge of the labels 36f. There are, however, no cuts in the marginal side edges of the supporting material 170. The composite web 30F can be fed by the toothed driver 47e shown in FIG. 24.

. Although the arrangement of cuts disclosed in FIGS. 10 and 25 diminishes the integrity of the web of supporting material, this construction is substantially entirely free of the deficiency of folding a flap or chad out of the plane of the web during delamination as in US. Pat. No. 3,501,365. Such folding out of a flap causes some adhesive, or gum as it is known in the art, adhering'to the edges of the flap or chad to be pulled away from the label material during delamination. In addition, such a folded out flap or chad will transfer the adhesive to guiding and feeding surfaces of the apparatus and flap can cause interference to feeding when pulling on the web of supporting material by means of a toothed driver.

Referring to the embodiment of FIG. 26, there is shown a composite web 306. Each group 38g of cuts, is shown in a U-shaped arrangement, and is comprised of transversely spaced apart longitudinal cuts 1755 and a transverse cut 1765 in the web of supporting material 177. The cuts 1758 are spaced from and in alignment with the ends of the cut 1768. The part of the supporting material 177 between the ends of the cuts 1758 and the cut 1768 provide frangible portions 1788. Label material 179 has transversely spaced apart cuts 175L and a transverse cut 176L. The horizontal cuts 1751. are spaced from the ends of the transverse cut 17 6L to provide frangible portions 178L. The label material 179 is provided with transverse cuts 333 to provide the labels 36g.-The composite web 30G has short, straight transverse cuts 180 in each marginal side edge of the labels 36g. There are, however, no cuts in the marginal side edges of the supporting material 177. It is preferred to use the composite web 30G with the driver 47 with its teeth 48 which are shaped in the manner best shown in FIGS. 7 and 8 rather than teeth 166 of a triangular shape as shown in FIG. 24.

In the embodiment of FIG. 28, there is shown a composite web 30H having groups 38h of cuts at regularly spaced apart intervals. Each group 3811 of cuts has a short transverse cut 181$ and a pair of converging cuts 182$ in the web of supporting material 183. The leading ends of the cuts 1828 are in transverse alignment with the transverse cut 1818. The one cut 1828 is spaced from the one end of the cut 181$ to provide a fold line 1838. The other cut 182$ is spaced apart from the other end of the transverse cut 1815 to provide a fold line 1848. The other ends of the cuts 1828 are spaced apart to provide a frangible portion 18 S. Cuts 181L and 182L are provided in web of label material 186 in alignment with respective cuts 1815 and 182$ in the supporting material 183. The cuts 181L, 182L, and short straight transverse cuts 187 serve to prevent switching of the labels when applied to merchandise. In the embodiment of FIG. 28 it is preferred that each group 38h of cuts be disposed between the end edges of labels 36h defined by transverse cuts 33h. As shown in FIG. 29, toothed driver 47e shows a tooth 166, which has ruptured the frangible portion 1858 in supporting material 183, in driving engagement with the supporting material 183. It is evident that flap 188$ folds along each cuts 1818 and the respective fold lines 183$ and 1845. To insure rupturing of the frangible portion 1858, the length of the frangible portion 1858 is about one-half as long as the fold line 183$ and one-half as long as the fold line 184$. The lengths of the fold lines 1838 and 1848 and the cut 1818 are equal.

Referring to the embodiment of FIG. 30, there is providecl a composite web 30K having groups 38k 01' cuts. Each group 38k of cuts includes curvilinear cuts 197$ in a web of supporting material 198. The one ends of the cuts 197S are spaced apart by a relatively substantial distance transversely of the composite web 30K. The other ends of the cuts 1978 are spaced apart only a relatively small distance by a frangible portion 198$. The group 38k of cuts also includes curvilinear cuts 197L in web of label material 199. The cuts 197L are in alignment with the cuts 197$ in the supporting material 198. Transverse cuts 33k in the label material 199 define the ends of the labels 36k. The cuts 197L and cuts 200 in the label material 199 serve to prevent switching of the labels once they have been applied to merchandise. I

With reference to FIG. 31, the toothed driver 47e is shown to be in driving engagement with the web of supporting material 198. One of the teeth 166 is shown to have ruptured the frangible portion 198$ and to be in driving engagement with the supporting material 198.

FIG. 32 shows an embodiment of a composite web 30L which is identical to the embodiment of FIG. 9, except that a composite web 30L is shown to have an additional group 381 of cuts between the marginal end edges of labels 361 formed by transverse cuts 331. In addition, each label 361 is shown to have two short transverse cuts 201 at each marginal side edge.

FIG. 33 shows a composite web 30M of labels which is identical to the composite web shown in FIG. 23, except that an additional group 38m of cuts is provided between the end edges of the labels formed by transverse cuts 33m.

FIG. 34 shows another embodiment of the composite web 30N which is identical to the composite web 30 (FIG. 2), except that the groups 38n of cuts penetrate,

that is extend only partially through the label material 202 as best shown in FIG. 35. It is also apparent from FIG. 35 that the group 38n of cuts extends entirely through the supporting material 203. While the construction shown in FIGS. 34 and 35 does substantially weaken the label material so as to render the labels 36n more difficult to switch once they have been applied to merchandise, they are less effective in this connection than would be the case as in the embodiment of FIG. 9, for example. FIG. 36 is a view similar to FIG. 35 but showing where the longitudinal cut is made partially through the label material 204 by perforating instead of completely cutting through the label material as in the embodiments of FIGS. 1 through 9 or as opposed to the partial cutting through the label material 202 as dis closed in FIGS. 34 and 35. Thus, in the embodiment of FIG. 36, composite web 30? has the group 38p of cuts entirely through supporting material 205 and through the label material 204 at spaced apart locations leaving tangs or lands 206 or the like between through-cuts 207.

It is within the scope of the invention to make the

cuts

33, 39L, 39S, 40L, 40S, 41L, 41S, L, 90S, 91L, 91S, 92L, 925, 330, L, 100$, L, 1108, 33e', L, 1205, 332, L, 160$, 163L, 1638,33), 169L, 1698, 1711., 1718, 33g, L, 175$, 176L, 176$, 33h, 181L, 181$, 182L, 1828, 33k, 197L, 1975, and 331, by means of scoring, perforating or the-like instead of by completely cutting through the respective label or supporting material. It is, however, preferred to make each of those cuts which is to define a feed edge a through out rather than a score or perforation cut.

Referring now to a label printing and applying apparatus generally indicated at 210 in the embodiment of FIGS. 37 through 62, and initially to FIG. 37, there is shown to be a housing or main frame generally indicated at 211. The housing or frame 211 is specifically shown to include a pair of

frame sections

212 and 213. Disposed within the housing 211 is a subframe generally indicated at 214 which comprises a pair of

subframe sections

215 and 216. The

frame sections

212 and 213 mount a platen 217 which includes a peel edge 218. A print head generally indicated at 219 is mounted by the subframe 214. More specifically, the print head 219 includes a plurality of selectable settable printing members 220 in the form of endless printing bands mounted by a print head frame 221. Extending from the frame 221 are a pair of

flanges

222 and 223. Gear sections or specifically racks 224 and 225 are provided at the ends of the

respective flanges

222 and 223.

Opposed tracks

226 and 227 are formed on the
