SECURITY LABEL
BACKGROUND OF THE INVENTION ~ ~
1. Field of the Invention -The present invention relates to security labels and, more particularly, to those used as a --responder target in a magnetic-type electronic article surveillance system.
2. Prior Art Electronic article surveillance systems have been used in retail stores for many years. The magnetic-type to which the present invention pertains utilize an electromagnetic interrogation field of predetermined frequency generated in a controlled area usually adjacent the customer exit. The security labels are generally constructed with a magnetic material which is designed to resonate at an harmonic of the frequency of the field when the label is passed through it. Electronic monitoring equipment senses the harmonic frequency generated by the presence of the label in the field and activates an alarm to alert store personnel of an unauthorized removal of merchandise from the store. In ~;
order to eliminate the need to remove the security labels from articles which have been purchased 80 that they do not set off the alarm, various means have been developed to deactivate the label so that it does not resonate when passed through the interrogation field. One such common means is to construct the label with a soft magnetic strip which will resonate at the desired frequency and provide a hard magnetic strip or multiple strips which when subjected to a relatively strong magnetic field will prevent the label from being sensed by the interrogation field. Such labels are disclosed, for example in U.S.Pat. Nos . 3,747,086 and 5,146,204.
Early security labels of this type were fabricated one at a time and were relatively expensive to "
213205~
produce. Subsequently, improvements have been made in their construction which allowed them to be produced in long continuous strips with the magnetic material running parallel to the length of the label sandwiched between a support material and an adhesive coating. The strips are then cut to length by the manufacturer, and sent to the retailer to be placed on the article of merchandise.
However, because these labels are separated at manufacturer they cannot be fed from a typical labeling gun from a continuous roll of such labels as is well known for dispensing non-security type labels as shown for example in U.S. Pat. No. 4,369,085.
SUMMARY OF THE INVENTION
The present invention overcomes the above-described difficulties associated with prior art security labels by providing a security label in which the magnetic strip extends across the label and the labels are formed in rolls which permit them to be fed through a conventional labeling gun. Such labels are, therefore, more convenient to use while being relatively inexpensive to produce.
The security label of the present invention comprise8 a face 8heet having adhe8ive applied to one 8ide, a magnetic target 8upport strip secured by the adhe5ive to the face sheet and having adhesive applied to its side opposite the side attached to the face sheet, a magnetic target strip secured to the face sheet by the adhesive thereon, a release liner releasably adhered to -~
and covering the adhesive on the face sheet and the magnetic target support strip. The magnetic target strip is preferably deactivatable and extends across the width - -~
of the label.
The present invention also provides a role of security labels which can be used in conventional labeling guns. The role of labels comprises a continuous 213205~ ~
release liner formed in a role and having means for cooperating with a drive mechanism of the label dispensing gun for unrolling the release liner and advancing it through the dispensing gun, a plurality of individual labels releasably adhesively secured to one side of the release liner and formed in a role therewith for movement therewith through the dispensing gun as the release liner is unrolled, each label including a face sheet and at least one magnetic target strip extending across each face sheet transverse to the length of the release liner and secured to its respective face sheet on a side adjacent the release liner so as to be released from the liner along with the face sheet. The role of labels also preferably having the target strip on each label parallel to the axis of the role. The role also preferably includes a magnetic target support strip which adheres to the face sheet and in turn is adhesively secured to the magnetic target strip. The role also preferably includes the magnetic target strip being deactivatable and each label has a width greater than its length and the magnetic target strip includes a single wire extending ac~o8s the width of the label and a plu~ality o~
deactivatio~ 81ug8 adhered at spaced lntervals along the length of the wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A role of labels shown generally as 10 of the preferred embodiment of the present invention is fabricated of a continuous release liner 12, which supports a series of individual labels 14 each constructed of a face sheet 16, a magnetic target strip 18 and a magnetic target support strip 20.
~ he role 10 is constructed and arranged to be dispensed from any one of a number of conventional labeling guns (not shown), such as those disclosed, for example, in U.S. Pat. Nos. 4,369,085 and 3,878,783. The role 10 is preferably wound around a cylindrical core 22 which is supported on or in the gun for rotation so as to allow the release liner 12 and the labels 14 which it supports, to be unwound and fed from the gun in a conventional manner. The end 24 of the role 10 i9 unwound and fed through the gun by the use of any feeding mechanism, such as for example, the use of a ratcheted feed wheel (not shown) which engages corresponding slits 20 26 formed in the release liner 12, although any other -form of feeding mechanism may be used. ~s the labels 14 are ~ed through the gun they are u8ually printed with price8 or other information. The labels 14 are then stripped from the release liner by causing the liner to turn about a sharp corner. The label 14 is then expelled from the gun and applied to the article. The expulsion of a series of labels 14 from the labeling gun and their application to articles can be achieved rapidly and is thus much more efficient when applying the security labels of the present invention than is achievable through the application of individual labels which have previously been cut by the manufacturer.
Referring now to the construction of the -individual labels 14, as best seen in Fig. 2, each face sheet 16 is separated from its adjacent face sheet during ' 21320~
the manufacturing process in a well known manner, while they are adhered to the release liner 12. Each face sheet 16 is coated with an adhesive on the side 28 ad~acent the release liner 12. The opposite side of the ~ -5 face sheet 16 is the side on which printing or other -indicia is applied. Applied on top of the face sheet 16 as viewed in Fig. 2, and adhered to the adhesive is a narrow thin magnetic target support strip 20 made of mylar or other similar material which will adhere to the adhesive on the ~ace sheet and remain with it when the face sheet is stripped from the release liner 12. The support strip 20, in turn, has an adhesive coating on its upper surface as shown in Fig. 2. The magnetic target strip 18 is adhered to the adhesive on the support strip 20 and stays with it when the labels 14 are stripped from the release liner 12.
The magnetic support strip 18 consists of an easily saturable magnetic material formed as a small continuous wire 30 which extends across substantially the width of a label 14. Positioned at spaced intervals on top of the wire 30 are a series of spaced apart deactivation slugs 32, all of which is secured by adhesive to the support strip 20. The wire 30 and deactivation 81ug8 37 can be constructed as di8closed in U.S. Pat. No 5,146,204 and will operate in the manner disclosed therein. It is to be understood, however, that other magnetic target materials and constructions can be utilized in the present invention, so long as they can be disposed substantially across the width of the label 14 and the release liner 12 and not parallel to the direction of length of the release liner 12 so as to - ~ `
require the labels 14 and liner 12 to be severed into individual units by the manufacturer and not supported by a continuous web, such as release liner 12, for separation by the retailer as they are applied to the articles. The magnetic target strips are preferably - ;~;
2~320~
secured to the face sheet 16 so that they extend parallel to the axis of rotation of the role 10 when disposed in the labeling gun.
In view of the above, it will be seen that the 5 several objects of the invention are achieved and other .:
advantageous results attained.
- ~ :
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all mat~er contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in .
a limiting sense.
