There is disclosed a composite web roll of pressure sensitive labels. The composite web comprises a composite label web including a carrier web and labels releasably adhered to the carrier web by pressure sensitive adhesive. By adhesively securing the underside of the carrier web of an end portion of the composite web to adjacent labels along the end portion, when the outer free end portion is unwound, the labels to which the adhesive is adhered are stripped from the carrier web. The disclosure also relates to method of making and using composite webs according to the invention.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to composite webs and to method of making and using 
same. 
2. Brief Description of the Prior Art 
In a known type of labeler depicted in U.S. Pat. No. 3,783,083 granted to 
Willlam A. Jenkins it is highly desirable to strip a predetermined number 
of labels from the carrier web before threading the carrier web through 
the labeler. This can be accomplished by manually picking some of the 
labels from an end portion of the carrier web. Alternatively the composite 
web can be partially threaded through the labeler just past the 
delaminator and then the portion of the composite web which projects out 
of the labeler can be manually grasped and the carrier web can be manually 
pulled about the delaminator to strip the desired number of labels from 
the carrier web. 
It is known in the prior art to wrap a pressure tape around the outer wrap 
of a label roll. The adhesive on the tape is in contact with and adheres 
to the labels on the outer wrap. Removal of the tape can result in removal 
of some or all of the labels on the outer wrap. 
It is also known in the prior art to apply adhesive to the underside of the 
carrier web of the outer wrap of a label roll to adhere the outer wrap to 
the labels on the inner wrap. This keeps the label roll intact. The 
adhesive was only applied adjacent the outer free end portion of the 
carrier web and extended in length up to about three labels or about three 
inches. This resulted in up to about three labels or three inches of the 
inner wrap being delaminated or removed when the outer wrap was manually 
unwound by the user. 
SUMMARY OF THE INVENTION 
In accordance with the invention, there is provided an improved composite 
label web roll and methods of making and using same, by which labels are 
automatically stripped from the carrier web for easy threading of the 
labeler. 
In accordance with a specific embodiment of the invention, there is 
provided a composite label web including a carrier web having a top side 
and an underside and a series of labels releasably adhered by pressure 
sensitive adhesive to the top side of the carrier web. The composite label 
web is wound into a roll which has an outer free end portion. The outer 
free end portion includes a first zone and a second zone. The first zone 
is between the outer free terminal end of the composite web and the second 
zone. Adhesive adheres the underside of the carrier web in the first zone 
to labels in the second zone. Unwinding of the end portion causes labels 
to be stripped from the second zone. The carrier web can then be torn 
between the first and second zones and thereupon the remainder of the 
outer free end portion which comprises the second zone can be threaded 
into the labeler. 
The invention also relates to method of making a composite web which 
results in a roll from which labels can be automatically stripped as the 
outer wrap is being unraveled, and to method of using such a web.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, there is shown a hand held labeler generally indicated 
at 10 having a housing 11 and a handle 12. An actuating lever 13 disposed 
at the handle 12 carries a gear sector 14 which drives a gear 15 which in 
turn operates the print head 15' and thereafter the feed wheel 16 in 
sequence. A roll R of a composite label web C is mounted on the housing 
11. The composite web C comprises a carrier web W to which labels n are 
releasably adhered by pressure sensitive adhesive A (FIG. 3). The 
composite label web C is threaded between a brake roll 17 and a support 
surface 18 and from there to and partially about a guide roll 19. From 
there the web C passes over a platen 20 which is aligned with the print 
head 15'. From there the carrier web W makes a sharp angle about a 
delaminator 21 at which the leading label L' is stripped or delaminated 
from the carrier web W. From there the carrier web W passes partially 
about a guide roll 22 to between the feed wheel 16 and a cooperating idler 
wheel 23. The carrier web W passes partially around the feed wheel 16 and 
loses contact with the feed wheel 16 at point P. From there the web W 
exits the housing 11 at 24. 
The print head 15' has printing bands 25 which are inked by an ink roller 
26 when the lever 13 is operated. As shown, the leading label L' is 
positioned in underlying relation to an applicator roll 27 following the 
printing portion of the cycle of operation of the labeler 10 and from 
there the leading label L' can be applied to merchandise using the 
applicator roll 27. 
The roll R is also shown in FIG. 2 to have a core 28. The composite web C 
have an outer free terminal end 29. 
FIG. 3 shows the composite web C with a continuous coating of the adhesive 
A on the underside of the labels L. There are feed slits or feed cuts 30 
in the carrier web W at equally spaced apart intervals along the 
longitudinal extent of the carrier web W. The feed slits 30 are engaged by 
teeth 16' on the feed wheel 16. There are security slits or cuts 31 in the 
labels L aligned with the feed slits 30. The slits 31 make the labels L 
susceptible to tearing when their removal from merchandise is attempted. 
As shown, the composite web C is feed in the direction of the arrow 32. 
According to the invention, adhesive 35 is applied to a first zone Z1 of 
the underside of the carrier web W. FIG. 8 shows an adhesive coating wheel 
33 rotatable in a fountain 34 and is in contact with the carrier web W. 
When the roll R has been almost completely wound up, the coating wheel 33 
and fountain 34 are moved into cooperation relative to the carrier web W 
to apply adhesive 35 to the underside of the carrier web W. The adhesive 
35 adheres to the labels L on an adjacent zone Z2. It should be noted that 
when the composite web C has been wound into roll form as shown in FIG. 2, 
the adhesive 35 holds the outer wrap OW in place. There is no need for 
tape to be applied to the outside of outer wrap OW across the terminal 
free end 29. 
The minimum number of labels L required to be stripped from the composite 
web C is equal to the number of labels which are on a length carrier web W 
in the path from the delaminator 21, partially about the roll 22, 
partially about the feed wheel 16 to point P. Thus, the minimum length of 
the stripe of adhesive 35 in the particular illustrated embodiment is 
enough to come into contact with the labels required to be removed in 
order to obtain the full benefits of the invention. 
It should be noted that the one end 36 of the adhesive 35 terminates short 
of the outer free terminal end 29 of the composite web C. This provides a 
manually graspable tab or handle 37 for the user to grasp and unwind the 
outer end portion 38 of the composite web C from the roll R. 
Outer end portion 38 of the composite web C includes zones Z1 and Z2. When 
the outer end portion 38 is unwound, the labels n in Zone Z2 are stripped 
from the carrier web W. The user then tears the carrier web W generally 
along a line indicated at 39, which is about where zones Z1 and Z2 meet. 
The distance between line 39 and a label L' should preferably be equal to 
or more preferably slightly greater than the distance along the path of 
the carrier web W from the delaminator 21 and the point P. With the 
composite web roll R prepared as indicated above, the user is now free to 
load the labeler 10. The carrier web W at zone Z2 is first inserted 
between the roll 17 and the support surface 18 while the actuator lever 13 
is held slightly depressed to release the brake roll 17. The carrier web W 
is then pushed along a guideway 40 to beyond the guide roll 19. From there 
the carrier web W is pushed over the platen 20 and the delaminator 21. The 
carrier web W is passed around the guide roll 22 and between the feed 
wheel 16 and the idler roll 23. Operation of the actuator lever 13 
advances the web W partially about the feed wheel 16 to the point P. Then 
the outer free end 29 of the web W is at or slightly beyond the point P, 
the label L' is at the platen 20 beneath the print head 15'. The label L' 
is now ready to be printed and dispensed into underlying relationship to 
the applicator roll 27. 
It is apparent that the number of labels L on the outer wrap OW of the roll 
R varies depending on the length of the labels L and the diameter of the 
roll R. It is therefore possible that the distance between the delaminator 
21 and the point P is equal to, less than dr greater than the length of 
the outer wrap OW. While the adhesive 35 is applied to the underside of 
the outer wrap OW, end 36' of the adhesive 35 can extend short of, beyond, 
or to the end of the outer wrap OW. However, it is preferred that the 
adhesive 35 start at the outer wrap OW even though it may extend to the 
inner wrap IW. In the event the adhesive 35 extends beyond the outer wrap 
OW into the inner wrap IW, it is apparent that labels L will also be 
removed from the next wrap NW which is adjacent the inner wrap IW. 
While the adhesive 35 is indicated to take the form of a continuous stripe, 
it can take the form of a selected pattern. 
It is preferred that the adhesive 35 be of a non-tacky adhesive, however, 
other types of adhesive such as pressure sensitive adhesive, can be used. 
Other embodiments and modifications of this invention will suggest 
themselves to those skilled in the art and all such of these as some 
within the spirit of this invention are included within its scope as best 
defined by the appended claims.
