Abstract
For producing identity cards, access cards, identification cards, or the like, containing electronic and/or electric components, including such with outwardly directed contacts, it is proposed that at least one central layer of the card, containing also the electronic and/or electric components or consisting thereof, be initially retained in floating condition by adhesive quantities applied as floating mass at least on one inner face, and be then progressively compressed to a thickness that is predetermined by stops, without any application of heat, and be finally cured so that the electric and/or electronic components are supported in the finished card, embedded in the intermediate adhesive layer so formed.
Claims18
A method for producing an identity card sandwich, said method comprising the steps of:
- positioning a plurality of card layers one on top of another, said plurality of card layers including at least an intermediate layer adjacent to a first of said plurality of card layers and at least one electronic component initially positioned on said intermediate layer;
- applying adhesive to at least one out of a first surface of said intermediate layer and an inner surface of said first card layer adjacent to said first surface;
- applying pressure without applying heat to said plurality of card layers to compress said card layers to a predetermined width;
- and
- curing said adhesive layer to secure said electronic component.
A method for producing an identity card sandwich in a press, said press including at least one stop component having a predetermined thickness for providing an impediment to the application of pressure on said identity card sandwich by said press, said method comprising the steps of:
- positioning a plurality of card layers one on top of another, said plurality of card layers including at least an intermediate layer adjacent to a first of said plurality of card layers and at least one electronic component initially positioned on said intermediate layer;
- applying adhesive to at least one out of a first surface of said intermediate layer and an inner surface of said first card layer adjacent to said first surface;
- applying pressure without applying heat to said plurality of card layers by actuating said press until said stop is engaged, whereby said adhesive is compressed in order to compress said plurality of card layers to said predetermined thickness of said stop;
- and
- curing said adhesive to secure said electronic component.
A method for producing an identity card sandwich, said method comprising the steps of:
- positioning a plurality of card layers one on top of another, said plurality of card layers including at least an intermediate layer adjacent to a first of said plurality of card layers and at least one electronic component initially positioned on said intermediate layer;
- applying adhesive to at least one out of a first surface of said intermediate layer and an inner surface of said first card layer adjacent to said first surface;
- applying pressure without applying heat to said plurality of card layers until an impediment to the application of pressure is reached, whereby said adhesive is compressed in order to compress said plurality of card layers to a predetermined thickness;
- and
- curing said adhesive to secure said electronic component.
A method for producing an identity card sandwich in a press, said press including at least a plurality off springs having a plurality of predetermined fixed stops for controlling the amount that said press can compress said identity card sandwich, said method comprising the steps of:
- positioning a plurality of card layers one on top of another, said plurality of card layers including at least an intermediate layer adjacent to a first of said plurality of card layers and at least one electronic component initially positioned on said intermediate layer;
- applying adhesive to at least one out of a first surface of said intermediate layer and an inner surface of said first card layer adjacent to said first surface;
- applying pressure without applying heat to said plurality of card layers by actuating said press;
- during said applying pressure step, said plurality of springs permit a gradual sequence of motions according to said plurality of predetermined fixed stops for the application of pressure by said press, whereby said plurality of predetermined fixed stops determine a thickness of said plurality of card layers;
- and
- curing said adhesive to secure said electronic component.
