DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the embodiment of FIGS. 1 through 8 , and initially to FIG. 1 , there is shown a package generally indicated at 40 including a roll 41 having a supply core 42 and a take-up core 43 . The core 42 is shown to have notches 44 , and the core 43 is shown to have notches 45 . The notches 44 and 45 are typically used in a printer for advancing a web generally indicated at 46 . Although notches 44 and 45 are illustrated, a greater or lesser number of notches, or no notches at all can be provided depending on the machine with which the cores are to be used.

FIG. 2 shows the web 46 as including a main web portion 47 which occupies most of the length of the web 46 . In this and in the other embodiments, the main web portion 47 has a coating and in particular a coating of ink and thus comprises an ink ribbon which includes a thin coating or layer of ink on a web of plastics film. The web 47 has a marginal end 48 to which a strip of pressure sensitive adhesive tape 49 is adhesively secured. The tape 49 is comprised of a flexible plastics film 50 with a uniform coating of adhesive 51 . The adhesive 51 adheres the tape 49 to the marginal end 48 and adheres the web 46 to the core 42 . The tape 49 overlaps the marginal end 48 and presents an exposed transversely extending adhesive stripe to the outer surface of the supply core 42 . The web 46 includes a main web portion 52 which comprises almost all of the web 46 , and the web 46 also includes a leader portion 52 ′. A transversely extending strip of adhesive tape 53 is comprised of a flexible plastics film 54 having a uniform coating of pressure sensitive adhesive 55 . The tape 53 is shown connecting the overlapped ink ribbon portion 47 and leader portion 52 ′. The leader portion 52 ′ is shown to be comprised of flexible leader strips 56 , 57 and 58 . The leader strips 56 and 57 are shown connected to each other by a transversely extending strip of adhesive tape generally indicated at 59 comprised of flexible plastics film 60 with a uniform coating of pressure sensitive adhesive 61 . Terminal first ends 62 and 63 ( FIG. 3 ) of the respective leader strips 56 and 57 are spaced apart and the tape 59 spans the space therebetween and is adhered to respective marginal first ends 64 and 65 of the leader strips 56 and 57 . A stripe of the exposed adhesive 61 shown by stippling in FIG. 3 is face-to-face with the take-up core 43 as best shown in FIG. 4 . The core 43 is secured to the stripe of adhesive 61 on the tape 59 . The adhesive 61 preferably permanently attaches or adheres the take-up core 43 to the leader portion 52 ′.

A transversely extending strip of adhesive tape generally indicated at 66 connects the leader strips 57 and 58 to each other. The tape 66 has a flexible plastics film 67 and a uniform coating of pressure sensitive adhesive 68 . Terminal ends 69 and 70 ( FIG. 3 ) of the respective leader strips 57 and 58 are spaced apart. The tape 66 spans across the space between the terminal ends 69 and 70 and is adhered to marginal ends 71 and 72 of respective leader strips 57 and 58 . The leader strip 58 provides a manually graspable tab.

While the leader portion 52 ′ is illustrated as being a composite of leader strips 56 , 57 and 58 and tapes 59 and 66 , the leader portion 52 ′can be comprised of a single film or leader portion with transverse stripes of adhesive at the locations where the exposed adhesive 61 and 68 exists.

The leader strip 57 is shown to have weakening 73 along a line transversely across the web 46 . The weakening 73 is preferably a line of perforations illustrated in FIGS. 2 , 3 and 6 of the drawings by broken lines and intervening circles and in FIGS. 4 , 5 , 7 and 8 by small circles. The flexible adhesive strips 49 , 53 , 59 and 66 are shown to have considerable thickness for the sake of clarity, but one skilled in the art will recognize that these adhesive strips are thin, by way of example not limitation, on the order of between about 15 to 100 Microns and preferably about 6 Microns thick and the coated web portion or ink ribbon 47 is between about 3 to 15 Microns and preferably about 8 Microns thick.

FIG. 2 shows indicia 74 stating instructions for use, for example the words “Pull Here”. A label 75 also bears indicia providing desired information.

In the embodiment of FIGS. 1 through 8 , the web 46 is preferably essentially entirely an ink ribbon except for the leader portion 52 ′. The web 46 is wound into the configuration best shown in FIGS. 1 and 4 . The exposed adhesive 68 is shown to hold the web 46 to itself. The adhesive 68 releasably adheres the web 46 to itself. For this purpose the adhesive 68 , like the adhesive 61 , may be of the permanent type. In that the adhesive 61 adheres to a take-up core 43 which is of paperboard material, the adherence is permanent. In the event the take-up core 43 were to be made of plastics material the aggressiveness of the adhesive should preferably be such as to adhere the web 46 permanently to the core 43 . The adhesive 68 may also be of the permanent type, but because the adhesive 68 is adhered to the leader portion 52 ′ comprised of plastics film such as polyethylene film the adhesive 68 is actually removably adhered to the film. If necessary, the adhesive 68 can be less aggressive than the adhesive 61 .

The web 46 extends beyond the roll 41 to provide an outwardly extending portion. The web 46 encircles both the roll 41 and the core 43 to provide the packaging or wrapping for the package 40 . In order to open or unwrap the package 40 , the user manually grasps the tab 58 and pulls in a direction away from the roll 41 , thereby releasing the web 46 from itself. Then the user tears the leader strip 57 along the line of weakening 73 . The part of the leader portion 52 ′ outwardly of the line of weakening 73 can now be discarded. Now the roll 41 and the take-up core 43 can be inserted into the utilization device, e.g. a printer, in which the web 46 is progressively unwound from the roll 41 and wound onto the take-up core 43 . In the illustrated embodiment of FIGS. 1 through 8 , the main portion of the web 46 of the roll 41 is an ink ribbon suitable for use in a printer for example a thermal printer. Indeed, almost the entire web 46 is comprised of ink ribbon.

In the manufacture of a package 40 , the ink ribbon is advanced from the ink ribbon production equipment to a leader-trailer bed (not shown) in the direction of arrow A in FIG. 6 . While in the leader-trailer bed, the ink ribbon is slit transversely into wide webs 80 and 81 and the wide web 80 is advanced in the direction of the arrow A while the wide web 81 remains stationary. Next, a composite leader web 52 W corresponding to the leader portion 52 ′ is advanced in the direction of arrow B, but at a level above the plane of the webs 80 and 81 . The composite leader web 52 W is wider than the distance between the wide webs 80 and 81 . The composite leader web 52 W has leader strips 56 W, 57 W and 58 W corresponding to leader strips 56 , 57 and 58 and has pressure sensitive adhesive tape or strips 53 W, 59 W and 66 W corresponding to the tape or strips 53 , 59 and 66 . The adhesive tape strip 49 W is attached to the tab strip 58 W and to the wide ink ribbon web 81 . Next the leader web 52 W is trimmed by slitting along lines 82 and 83 which run along the side edges of the webs 80 and 81 . Thus, the webs 80 and 81 are connected by a leader web 52 W for advancement to a rewinder diagrammatically illustrated in FIGS. 7 and 8 . As the webs 80 and 81 and the intervening leader web 52 W are advanced, slitting knives (not shown) slit the webs 80 and 81 and the web 52 W along lines 83 into, for example, three narrow webs such as the web 46 .

With reference to FIGS. 7 and 8 , the rewinder 84 can rewind the three narrow webs. The rewinder 84 has two opposed turrets 85 and 86 on which supply cores 42 can be mounted. Each turret 85 and 86 also has opposed pairs of holders 87 and 88 on which take-up cores 43 can be mounted. The rewinder 84 also has opposed edge guides 89 and 90 .

With reference to FIG. 7 , the rewinder 84 is shown in a position in which the ink ribbon 47 is almost entirely wound onto the core 42 on the turret 86 . The turret 84 is now indexed clockwise into the FIG. 8 position at which the exposed stripe of adhesive 61 on the tape 59 is against and in contact with the outer periphery of the take-up core 43 . The machine operator now lightly presses the tape 59 against the take-up core 43 to better adhere the adhesive 61 to the take-up core 43 . Next the operator presses the tape 49 against the core 42 so that the adhesive 51 adheres permanently against the core 42 . The operator then peels the tape 49 from the leader strip 58 and presses the remainder of the tape 49 against the core 42 . The operator now removes the take-up core 43 from the turret and between edge guides 90 , takes up any slack by winding the leader portion 52 ′ around the ink ribbon roll 41 (shown at the bottom of FIG. 8 ), and adheres the exposed stripe of adhesive 68 of the tape 66 to the outer surface of the web 46 . Although the adhesive 68 is adhered to the outer surface of the roll 41 it can be attached anyplace on the outer wrap. The now-completed package 41 is slipped off the turret 85 , and the same process can proceed for the next ink ribbon.

In the embodiment of FIGS. 9 through 11 , the same reference characters are used as in the embodiment of FIGS. 1 through 8 for components having the same structure, function and relative location, with the addition of the letter “a”. The package 40 a differs from the package 40 only in that there is no line of weakening such as the line of weakening 73 of the package 46 . The manner of use of the package 40 a differs from that of the package 40 in that after the user pulls on the tab 58 a to unstick the adhesive 68 a of the tape 66 a from the outer surface of the roll 41 a , the leader strip 57 a and the tab strip 58 a can simply be wrapped up about the take-up core 42 as after the take-up core 42 and the supply core 44 a are installed in the printer.

In the embodiment of FIGS. 12 through 14 , the same reference characters are used as in the embodiment of FIGS. 1 through 8 for components having the same structure, function and relative location, with the addition of the letter “b”. The package 40 b differs from the package 40 , as follows: The leader strip 56 b is permanently secured to the core 43 b by a transversely extending strip of adhesive tape generally indicated at 91 . The tape 91 is comprised of flexible plastics film 92 with a coating of permanent pressure sensitive adhesive 93 . A portion of the width of the tape 91 is adhered to the leader strip 56 b and the remainder is adhered to the take-up core 43 b . A marginal end of a transversely extending strip or tab 94 is spaced from the leader strip 57 b . A transversely extending strip of pressure sensitive tape 95 spans across the respective marginal ends of the tab strip 94 and the leader strip 57 . The tape 95 comprises film 96 and a coating of permanent pressure sensitive adhesive 97 . The adhesive 97 is releasably adhered to the tape 91 . As best shown in FIG. 13 , the tape 66 b releasably adheres the leader strip 57 b to the outer surface of the web 46 b at the roll 41 b . When it is desired to unwrap the package 40 b , the user pulls the tab 94 and separates the tape 95 from the tape 91 . By continuing to pull on the tab 94 the user pulls the tape 66 b loose from the outer surface of the web 46 b . The user can then discard the leader strip 57 b the tapes 66 b and 95 and the tab 94 as a unit.

In the embodiment of FIGS. 15 through 17 , the same reference characters are used as in the embodiment of FIGS. 1 through 8 for components having the same structure, function and relative location, with the addition of the letter “c”. The leader strip 56 c is shown to have a marginal end 98 located between a transversely extending transverse strip of double-faced adhesive tape generally indicated at 99 and the take-up core 43 c . The tape 99 is comprised of a flexible plastics film 100 with a coating of permanent adhesive 101 on one side and a coating of permanent adhesive 102 on the other side. The tape 99 overlays the marginal end 98 and the outer periphery of the take-up roll 43 c as best shown in FIG. 16 . The adhesive 101 is releasably adhered to the outer surface of the roll 41 c . In order to unwrap the package, the user simply grips the outside of the roll 41 c and the outside of the take-up core 42 c and pulls the adhesive 101 free from the outer surface of the roll 41 c . The tape 99 stays with the take-up core 43 c as the ink ribbon 47 is used in the printer.

In the embodiment of FIGS. 18 through 20 , the same reference characters are used as in the embodiment of FIGS. 1 through 8 for components having the same structure, function and relative location, with the addition of the letter “d”. The package 40 d includes a transversely extending strip of tape generally indicated at 103 comprising a plastics film 104 having a coating of permanent adhesive 105 . The tape 103 is adhered to a marginal end 106 of the leader strip 56 d , to the outer periphery of the take-up core 43 d , to marginal end 107 of the tab 58 d and to the other surface of the roll 41 d as best shown in FIG. 19 . To unwrap the package 40 d , the user pulls on the tab 58 d and separates the tape 103 from the outer surface of the roll 41 d . In use, the tape 103 and the tab 58 d thereon can be wound around the take-up core 42 d as the ink ribbon 47 d is being used in the printer.

It is evident that in the embodiments of FIGS. 1 through 20 to the take-up core is within or is enclosed by the portion of the web that forms the wrapper. In these embodiments, by way of example not limitation, the main web portion 52 is about 200 meters in length and the leader portion 52 ′ is about 0.5 meter in length.

The leader portions 56 i , 117 i , 144 and 147 and tapes 116 i , 142 and 146 comprise a leader 148 . As shown, the leader 148 extends outwardly beyond the roll R. FIG. 35 shows the leader 148 attached to itself by the adhesive 145 of the tape 146 . The leader portions and tapes which comprise the leader 148 preferably extend entirely across the web which is comprised of both the ink ribbon 47 i and the leader 48 , as in the embodiment of FIGS. 21 through 25 . The line of weakening 120 i preferably extends entirely across the web transversely.

The adhesives 141 and 119 i are preferably permanent adhesives which adhere the leader 148 permanently to the ink ribbon 47 i and to the take-up core 43 i . There is no need or intention to remove the leader 148 from the ink ribbon 47 i or to remove the core 43 i from the leader 148 . The adhesives 143 and 145 are preferably removable adhesives which adhere the leader 148 releasably or removably to itself, and specifically, to the surface of the roll R, at spaced locations.

When it is desired to use the package 40 i , the user grasps the tab or leader portion 147 and pulls so as to release the adhesive 145 from the remainder of the leader 148 . By unwinding the leader portion 148 , and by further pulling the leader portion 117 I, the leader portion 117 i is torn off at the line of weakening 120 i . The roll 41 i and the take-up core 43 i are now ready to be loaded into the printer for use. The part of the leader portion to the left of the line of weakening 120 i as seen in FIG. 36 , leader portions 144 and 147 and associated tapes 142 and 146 can now be discarded as a unit.

The embodiment of the package 40 j disclosed in FIGS. 37 and 38 is identical to the embodiment of FIGS. 21 through 25 except as noted hereafter. Accordingly, the same reference characters are used with the addition of the letter “j” for components having the same structure, function and relative location. The package 40 j includes a first leader portion 149 attached by a strip of adhesive tape 115 j to the ink ribbon 47 j . Adhesive 150 on the tape 115 j is preferably a permanent adhesive which permanently adheres the first leader portion 149 to the ink ribbon 47 j . A label 75 j is adhered to the outer surface of the leader portion 149 . A double-faced adhesive tape generally indicated at 151 has a plastic film 152 , layers of preferably permanent adhesive 153 and 154 , and a release liner 155 releasably adhered to the adhesive layer 154 . Disposed beyond the adhesive tape 151 is a line of weakening 120 j which extends preferably entirely transversely across the web 156 . A strip of adhesive tape 157 having a layer of adhesive 158 is adhered to a marginal edge of the leader portion 159 . The adhesive 158 is preferably of the removable type. As shown in FIG. 37 , the adhesive 158 releasably adheres the leader portion 149 of a leader generally indicated at 160 to the outer surface of the roll 41 j . The leader 160 is composed of the leader portions 149 and 159 and the tape 157 .

In order to use the roll R, the user grasps the leader portion or tab 159 and pulls the leader 160 free from the outer surface of the roll 41 j at the adhesive 158 and then the user tears the leader portion 149 at the line of weakening 120 j . The user can now peel the release liner 155 from the adhesive 154 and attach the remainder of the leader 149 to a take-up core, like the take-up core 43 e for example, by means of the adhesive 154 . Alternatively, the user can attach the take-up core to the adhesive before the tape 157 released from its adherence to the surface of the roll 41 j and before the leader 149 is torn along the line of weakening 120 j . The adhesives 153 and 154 are preferably permanent adhesives which adhere permanently to the leader portion 149 and to the core, respectively.

The part of the leader portion 149 to the left of the line of weakening 120 j in FIG. 38 and the associated tape 157 and leader portion 159 , as well as the release liner 155 can be discarded when the package 40 j has been opened and the core has been attached.

In the case of an ink ribbon in the various embodiments, the ink ribbon 47 through 47 j is comprised of a flexible plastics film-onto which ink has been coated. The film is for example polyethylene. The adhesives used in the various embodiments are made with adequate aggressiveness to serve their intended function.

The invention is not limited to ink ribbons unless an ink ribbon is recited in a particular claim. Rather the invention is useful with various types of webs.

Unless otherwise indicated, the particular order of the steps recited in the appended claims is not critical; the particular order of steps can be changed without departing from the spirit of the invention.

Other embodiments and modifications of the invention will suggest themselves to those skilled in the art, and all such of these as come within the spirit of this invention are included within its scope as best defined by the appended claims.
