Abstract

This invention concerns a process and device for producing anti-theft elements for electronic anti-theft securing of articles. The anti-theft elements are made of at least two layers. The invention also concerns a strip material made using the process. The aim of this invention is to present a simple, economical process, a corresponding device for producing a strip material and a strip material for securing articles electronically which is made by the process. As for the process of this invention, the aim is achieved in that segments of a predetermined length of a second web of material are fed and applied on a first continuous web of material perpendicular to the running direction said first web of material.

Claims

1. A device for producing protective elements for the electronic protection of objects, the protective elements consisting of at least two layers of material web having a first material web and a second material web, the first material web defining a running direction, comprising:

a guide device for the first material web;

at least one dispensing device arranged perpendicularly to said guide device for dispensing sections of predetermined length of the second material web to the first material web;

a conveying belt for receiving the sections of predetermined length of the second material web from said at least one dispensing device;

one of a vacuum source and magnet for fixing said sections to the first material web; and

a control device for controlling said conveyor belt so that said sections are successively dispensed from said at least one dispensing device and are fixed to the first material web according to one of;

side by side and spaced apart transverse to the first material web.

2. The device as defined in claim 1 further comprising:

a pressure roller situated transversely to the running direction of the first material web, said pressure roller being movable up and down and presses the sections of predetermined length of the second material web against the first material web when a given section of predetermined length of the second material web reaches a preselected longitudinal position in relation to the first material web.

3. The device as defined in claim 2, further comprising:

a stop or a sensor for detecting the sections of predetermined length of the second material web; and

a control device to which said stop or sensor is connected, said control device moving said pressure roller against the first material web when said stop or sensor indicates that a section of predetermined length of the second material web has reached its preselected longitudinal position.

4. The device as defined in claim 2, wherein n dispensing devices are provided, arranged at a spacing of (2n+1)*(b+z), wherein b represents the width of the sections of predetermined length of the second material web, and z represents the desired spacing between two successive sections of predetermined length of the second material web.

5. The device as defined in claim 4, wherein the running speed of the first material web is determined by said control device such that the sections of predetermined length of the second material web are applied in a continuous manner to the first material web.

6. The device as defined in claim 2, wherein said conveyor belt is provided with openings.

7. The device as defined in claim 2, further comprising:

a storage roller, wherein the first material web with the sections of predetermined length of the second material web define a finished tape material, and wherein the finished tape material is wound on said storage roller.
