A LABEL FEEDER

Abstract: The object of the invention is a label feeder applying labels with electromagnetic wave information under a linerless label web, before this web is applied on the product. By using a label feeder using linerless label web there is a possibility for printing of linerless label web, application of a label with electromagnetic wave information giving or taking information, and inline control before application.

Description: A LABEL FEEDER Technical Field The present invention relates to a label feeder, in which a web with electromagnetic wave information or a label with electromagnetic information is applied on a linerless label web. Technical Background When self-adhesive labels with electromagnetic wave information today are applied, the most common method is first to apply a label with electromagnetic wave informa- tion and then a graphic label on top thereof . The reason for positioning a graphic label (for example a price label) usually on top thereof is for concealing the label with electromagnetical wave information (for example an alarm) . A currently used technique is that at label manufacture, before the labels are stamped out of their carrier web, the combined, self-adhesive label front material web is removed from its carrier web (usually silicon paper) , whereupon the label with electromagnetic wave information (for example a label with a memory circuit and an antenna or a coil/capacitor with an antenna) is applied on the adhesive. The self-adhesive front web is then joined with the carrier web, whereupon the label is stamped out of the front web, so that the label with the electromagnetic wave information is below and concealed. This label can then be applied on the product in an ordinary label dispenser. In this case thermo printii g or thermo transfer printing is a problem, as this printing requires a plane surface, and with a label with electromagnetic wave information below the surface is uneve . One technique is to apply the label with electromagnetic wave information in a laminate between two material layers, which gives the same problem as mentioned above. Another problem today is that each and every mechanical influence or passing of an undesireable electromagnetic field in certain cases influences the stored information or means that it can not receive the desired information. For this reason the influence shall be as small as possible. The function of the label with electromagnetic wave information is for example to receive information via radio waves and store this information in a memory and then later emit this information via radio waves at another occasion, or that the label has a circuit with coil and capacitor, which in a radio wave field emits a wave length of its own, which then can be indicated as an alarm. Objects and Most Important Features of the Invention The object of the invention is to accomplish a label feeder, which applies a label with electromagnetic wave information under a linerless web, leading to graphic labels. The label feeder gives information to and fetches information from the label with electromagnetic wave information shortly before the graphic label is applied on the product. The linerless label web can be covered with adhesive on one side and with low adhesive substrate on the other side or be partly covered on both sides, both longitudinally or transversly. By using a label feeder with linerless labels as carriers and as covering elements, there is a possibility to print on an even material web and to apply the label with electromagnetic wave information in line before the application on a product, whereby a material saving and thus cheaper design is obtained. By using thifs label feeder there is also space for other functions. Description of Drawings Fig 1 is a side view of the feeder. Fig 2 is a side view of the feeder with a cutter for the web with electromagnetical wave information. Fig 3 is a side view of the feeder with a carrier web for the labels with electromagnetical wave information. Description of Embodiments A linerless material roll is numbered 1 in Fig 3. A linerless material is a label material with self-adhesive material on the lower side and with low adhesive material or substrate (usually silicon) on the upper side. The linerless material can have such self-adhesive and low adhesive substrates over its entire surface or only partly. The linerless material (usually thermo or thermo transfer) passes a printer head 2, which adds graphic information. A label 8 with electromagnetic wave information (usually a memory circuit or a self-oscillating coil/capacitor) is applied on the lower side of the linerless material. These labels are present as self-adhesive labels on a carrier web in a roll 3. The empty carrier web is then rolled on a roll 9. A driven roll 10 makes the label with electromagnetic wave information to stick to the adhesive on the linerless web by means of pressure. The combined web then passes a programming station 5, where the label with electromagnetic wave information receives information, via for example radio waves, an information which is then stored. Further, the combined web passes a control station 6, which via for example radio waves controls that the label with electromagnetic wave i formation functions properly. The combined web finally passes a cutting equipment 7, which cuts the linerless web in suitable labels.

Claims: CLAIMS 1. A device called a label feeder, characterized in that linerless label material is unrolled from a roll (1) and with its adhesive side is brought against a material with electromagnetic wave information from a roll (3) and that the combined web is then cut (7) in suitable lengths. 2. A label feeder according to claim 1, characterized by a printer head (2) , which provides graphic information to the linerless material. 3. A label feeder according to any of the preceding claims, characterized in that a sender (5) emits digital information via electromagnetic waves to the material with electromagnetic wave information. 4. A label feeder according to any of the preceding claims, characterized in that a sender and a receiver (6) controls the function of the label (11) with electromagnetical wave information via electromagnetic waves. 5. A label feeder according to any of the preceding claims, characterized in that the web with electromagnetic wave information is brought forward and is cut (4) in suitable lengths, before it is combined with the self-adhesive linerless material. 6. A label feeder according to any of claims 1 - 4, characterized in that the electromagnetic wave material is stamped self-adhesive labels (8) on a carrier web, which is low adhesive treated and is rolled after the labels with electromagnetic wave information are dispensed on the linerless material. 7. A label feeder according to any of the preceding claims, characterized in that the adhesive or the low adhesive material is applied on only parts of the surface of the linerless material. 8. A label feeder according to any of the preceding claims, characterized in that the linerless material is preprinted with colour or information.
