[0001] The invention relates to a unit for use in the production of a multilayer flexible
data carrier card, comprising a first and a second outer layer of transparent plastics
film material, and an intermediate layer which is disposed between these two layers
and is provided with data and whose peripheral edge lies at a distance from and within
the peripheral edge of the two layers, the two outer layers being provided, on the
intermediate layer side, with an adhesive coating and at least the peripheral edge
parts of the outer layers, which project beyond the peripheral edge of the intermediate
layer, are firmly bonded together by means of the adhesive coating. A multilayer
flexible data carrier card of the above type is known
per se. De known card is produced starting from a lamination unit comprising a pair of transparent
sheets on either side of a release sheet with the transparent sheets having adhesively
coated faces in opposed engagement with the release sheet. First, one of the transparent
sheets is separated from the release sheet and a card-like article is adhered to one
transparent sheet. Next, the release sheet is separated from the other transparent
sheet and the other transparent sheet is adhered to the card-like article and any
areas of the one transparent sheet beyond the card-like article.
[0002] The known lamination unit has a number of disadvantages.
[0003] For the orignal formation if the unit it is necessary to inert a release sheet between
two adhesively coated sheets, which makes the lamination unit relatively expensive.
Moreover, making a multiplayer data carrier card starting fom the known lamination
unit is rather complicated and time consuming. Several sheets have to be separated
and the separate card-like article must be positioned accurately with respect to the
transparent sheets. It is therefore the object of the invention to provide a unit
for use in the production of a multilayer flexible data carrier card which does not
present the above disadvantages.
[0004] This object is achieved according to the invention by a unit of the above type which
is characterized in that it consists of a carrier sheet on which at least one transparent
self-adhesive label of plastics film material is detachably fastened, this label
being of a shape which is substantially symmetrical to at least one line of symmetry
and, on one of the lines of symmetry, is provided with a weakening of its wall which
extends right across it and forms a fold line, and which divides the label into two
substantially equal halves, and that that portion of the carrier sheet which is situated
within the peripheral edge of one of the two halves of the label is provided with
a first wall weakening lying at a distance from the peripheral edge.
[0005] The unit according to the invention is a very simple two-layer product which can
be produced in great series at relatively low costs. Furthermore, with a unit of this
type a multilayer flexible data carrier card can be produced in a very simple manner,
while data can be applied to the card by the supplier or else by the user himself.
After production of the card these data are fully protected by layers of plastics
film against external influences.
[0006] Data are expediently applied, or can be applied, on that portion of the carrier sheet
which is situated inside the first wall weakening, on the side not in contact with
the label. This portion of the carrier sheet will be used as the data carrier intermediate
layer of the card, and the side referred to is particularly suitable for marking data
by printing or writing.
[0007] In one embodiment that portion of the carrier sheet which is situated inside the
first wall weakening can be provided with at least one second wall weakening. That
portion of the carrier which is situated inside a wall weakening of this kind is intended
to be removed and to be replaced by another data carrier, for example a photograph.
[0008] On the side which is not in contact with the carrier sheet the label can be marked
with data, for example data which are the same for all the cards and which require
no special protection.
[0009] The carrier sheet advantageously consists of paper, which on the label side is provided
with an anti-adhesive coating, so that on the one hand the label can easily be removed
from the carrier sheet and on the other hand data can easily be marked on the carrier
sheet by printing or writing, and the label consists of vinyl material.
[0010] The invention also relates to a chain of units according to the invention comprising
a carrier web on which a plurality of labels are attached and which can be provided
between the labels with a wall weakening for the purpose of folding the carrier web
and/or tearing off a portion of the carrier web.
[0011] Finally, the invention relates to a method of producing a multilayer flexible data
carrier card according to the invention, which method is characterized in that, starting
with a sheet according to the invention, the necessary data are applied on that portion
of the carrier sheet which lies inside the first wall weakening, the label is removed
from the carrier sheet, the aforesaid portion of the carrier sheet remaining on the
label, the label is folded around the fold line and the two halves of the label are
placed with their adhesive sides one against the other, enclosing the portion of the
carrier sheet which has remained on the label.
[0012] The invention will now be explained with reference to one example of embodiment and
with the aid of the drawings, in which:
Figure 1 shows a particular embodiment of a card according to the invention;
Figure 2 is a section on the line II-II through the card shown in Figure 1, the thickness
of the card being represented on a larger scale;
Figure 3 shows a view of the label side of a sheet to be used for producing the card
shown in Figure 1; and
Figure 4 shows the other side of the sheet shown in Figure 3.
[0013] The multilayer data carrier card shown in Figures 1 and 2 consists of a first outer
layer 1 and a second outer layer 2 of transparent plastics film material, and of an
intermediate layer 3 disposed between these two layers. Certain data 4, 5, 6, which
can be seen through the transparent layer 1, are marked on the intermediate layer
3.
[0014] The peripheral edge 7 of the intermediate layer lies at a distance from the peripheral
edge 8 of the two outer layers 1, 2. These outer layers 1 are provided with an adhesive
coating on the side in contact with the intermediate layer 3. These adhesive coatings
ensure that at least those edge portions 9 of the outer layers 1, 2 which project
beyond the peripheral edge 7 of the intermediate layer 3 are firmly bonded to one
another.
[0015] The intermediate layer 3 is thus completely enclosed by the two layers 1, 2, so that
the data 4, 5, 6 on the intermediate layer are protected against damage by external
influences, for example mechanical influences.
[0016] The intermediate layer 3 may be made of various materials, but preferably consists
of paper. The outer layers 1, 2 preferably consist of vinyl material.
[0017] The thickness of the different layers is adapted to the desired stiffness of the
card.
[0018] As can be seen in figures 1 and 2, a certain portion of the data carrier intermediate
layer can be replaced by another data carrier 10, for example a photograph.
[0019] Figures 3 and 3 shows a sheet which can be used for producing the above-described
multilayer card. This sheet consists of a carrier sheet 11, on which at least one
transparent self-adhesive label 12 of plastics film material, for example vinyl material,
is attached. The label 12 is detachably secured to the carrier sheet 11 in a manner
known for self-adhesive labels.
[0020] In the embodiment shown in Figure 3 the label 12 has a substantially rectangular
shape. In the middle of the label a wall weakening 13 is provided which forms a fold
line and divides the label into two equal halves 14 and 15. The dimensions of the
label are such that the dimensions of the two halves 14, 15 correspond to the dimensions
of the card which is to be formed.
[0021] That portion of the carrier sheet which is situated inside the peripheral edges 16,
14 of the half 14 of the label 12 is provided with a first wall weakening 17. This
will usually be in the form of a cut right through the carrier sheet 11.
[0022] On that portion of the carrier sheet 11 which is situated inside the wall weakening
17 certain data are marked on the side shown in Figure 4. In addition, there is room
for applying further data 5, 6.
[0023] In figure 4 the portion 18 of the carrier sheet 11 is provided with a second wall
weakening 19, which is likewise usually in the form of a cut right through the carrier
sheet.
[0024] The material of the carrier sheet 11 is preferably paper, which on the side in contact
with the label 12 is provided with a known anti-adhesive coating, so that the self-adhesive
label 12 can be detached from the carrier sheet, while on the other side the carrier
sheet can be marked with data in a simple manner by printing or writing.
[0025] On the side not in contact with the carrier sheet, certain data 20 and 21 can in
addition be marked on the label. These data will subsequently be on the outside of
the card and will therefore not be protected.
[0026] Starting with the above-described sheet, the production of the data carrier card
proceeds as follows.
[0027] The necessary data 4, 5, 6 are first applied on that portion 18 of the carrier sheet
which lies inside the first wall weakening 17. The label 12 is then removed from the
carrier sheet, the portion 18 of the carrier sheet remaining on the label 12. The
label is then folded along the fold line 13, and the two halves 14, 15 of the label
are finally laid with their adhesive sides one against the other, enclosing the portion
18 of the carrier sheet which remained on the label 12. A two-sided laminated card
is thus obtained, the data marked on it being completely covered over. After about
1 hour from the time when the label is folded, the card will already be bonded together
so firmly that it can no longer be pulled apart without being damaged. This prevents
forgeries.
[0028] If necessary, before the two halves 14 and 15 of the label are brought together,
that portion 22 of the carrier sheet which lies inside a second wall weakening 19
is removed from the label 12 and replaced by another data carrier 10, for example
a photograph.
[0029] Figures 3 and 3 show a carrier sheet having only one label 12. It is also possible
that a plurality of are interconnected to form a carrier web on which a plurality
of labels 12 are attached. In this case a wall weakening, such as perforations 23,
may be provided between the labels for the purpose of folding the carrier web and/or
for tearing off a portion of the carrier web.
[0030] An embodiment of this kind will in particular be selected when the data have to be
applied on the carrier web by means of a typewriter or computer printer. In the latter
case the carrier web will be provided with positioning holes 24.
[0031] The above-described multilayer card has many possible applications. The card according
to the invention will as a rule be used where a cheap flexible data carrier card is
needed.
[0032] In particular, the card according to the invention can be used as a membership card,
an admission card, a subscriber's card for libraries, videotheques, (sports) meetings,
clubs, chain stores, hospitals, public transport, and various institutions. Since
the sheets from which the cards are produced can also be processed on typewriters,
the cards can also be utilized by small users.
