DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for clothes and other objects which device after activation is arranged to function as protection against theft of the object in question by cooperation with an alarm indicator gate, a hand scanner or any similar control apparatus.
Special alarm tabs have been mounted in order to reduce theft of clothes and other objects for sale in shops, onto said objects in the shop and which have been functioning according to RF, radio frequency or EM, the electromechanical principle. The alarm is activated inside the shop or inactivated respectively by being moved past a plate or some other set-up for this purpose. Special aids are then needed in order to remove the alarms from the objects without damaging the objects. Said known alarms are easy to recognise and difficult to conceal if so wished.
WO,A1, 94/29503 relates to a label with inserted alarm label while U.S. Pat. No. 5,003,291 and U.S. Pat. No. 5,017,907 shows electromagnetic fibre which may be used for alarm purposes.
However, it is not previously known to have woven alarm labels where the alarm thread is allowed to function as the weft threads or warp threads of the label in question.
If loose separate alarm threads were woven in or in some other way attached in a label according to prior art, it would be simple for those who wished to remove aforementioned alarm thread and thereby destroy the alarm function of the label.
Thus by instead letting the alarm be woven in as the weft or warp thread of the woven label, it is simple to achieve to produce alarming labels and where the alarm may not easily be recognised in order to e.g. afterwards be removed by dishonest persons.
However, it is possible to use thread for example according to prior art, for providing desired alarm function but by applying this alarm thread in a special manner as a normal component of the label.
The main object of the present invention is therefore in the first hand to solve the problem of being able to easily conceal the alarm in the considered objects by simple and well functioning means and not having to alarm mark afterwards and also not having to remove the alarm in the shop.
These objects are achieved by means of a device in accordance with the present invention, which is mainly characterized in that a label which is woven comprises an electronic alarm inserted into the woven label, wherein the alarm is formed by means of weft threads that are woven into the warp threads of the label to form an alarm circuit, or that the alarm is formed by means of a number of the warp threads which are arranged to form an alarm circuit.
Another object of the invention is to find a method which makes it possible to manufacture said alarm labels efficiently and simply. This object is achieved by means of a method which is substantially characterized in that a number of threads are woven into the other threads of the formed label so that they form an alarm circuit.
Finally, one object of the invention is to find a well functioning use of the alarm label.
Said final object is achieved by means of an use according to the invention, which is substantially characterized in that the label is sewn or by some other manner attached to the garment or any other intended object before activation of it, wherein the regular marking label of the garment is used as an alarm label.
The invention is described here below as a number of preferred embodiments, wherein is referred to the accompanying drawings, in which
FIG. 1 shows a garment that has been provided with a woven mark label including alarm,
FIG. 2 shows a procedure step during production of labels,
FIG. 3 shows a weaving apparatus for production of labels, and
FIG. 3A shows alternatives thereof.
The present invention makes it possible to allow inserting of electronically working alarms already at the factory in which is produced garments and other objects which are desired to be provided with alarm. Thus, a device 1 intended for clothes 2 and other objects, which after activation are arranged to function as theft
