Abstract
Abstract A small article such as portable electronic token of the smart card type is manufactured by means of a reaction injection moulding technique in which electronic circuitry (1,2) is encapsulated within a hardenable plastics material (8). The labels on the faces of the card (6) are used as a mould release agent to enable easy release of the token, once hardened, from the mould (10). The articles are conveniently manufactured by a continuous process using moving belts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A method of manufacturing portable electronic tokens comprising one or more electronic components and data input/output means encapsulated within a plastics body and high tensile modulus members disposed as skins on at least two opposing main faces of the body and having graphics thereon; which method comprises locating the high tensile members, against the side of a mould, locating the components between the members, injecting a reaction injection mouldable plastics material into the mould such that it encapsulates the components but is prevented, by the members, from contacting the surface of the mould, allowing the material to harden, and, removing the token from the mould.
Claim 2
Independent Claim
105 words
A method of manufacturing portable electronic tokens comprising one or more electronic components and data input/output means encapsulated within a plastics body and high tensile modulus members disposed as skins on at least two opposing main faces of the body and having graphics thereon; which method comprises locating the high tensile members, against the side of a mould, locating the components between the members, injecting a reaction injection mouldable plastics material into the mould such that it encapsulates the components but is prevented, by the members, from contacting the surface of the mould, allowing the material to harden, and, removing the token from the mould.
Claim 3
Dependent Claim
13 words
A method as claimed in Claim 1 wherein the tokens are smart cards.
Claim 4
Dependent Claim
15 words
A method as claimed in Claim 1 wherein the portions of the token are co-extruded.
Claim 5
Dependent Claim
31 words
A method as claimed in Claim 1 or Claim 2 wherein the mould comprises two endless belts which are located to cooperate in use to form a continuously moving mould cavity.
Claim 6
Dependent Claim
41 words
A method as claimed in Claim 1 or Claim 2 wherein the high tensile members are arranged in two continuous sheets and are transported through the moulds carrying the components and plastics material; the individual tokens being subsequently separated after hardening.
Claim 7
Dependent Claim
41 words
A method as claimed in Claim 5 wherein after the components and plastics material have been introduced between the members, the edges of the members are sealed to form a sealed structure within which the plastics material is allowed to harden.
Claim 8
Dependent Claim
19 words
A method as claimed in Claim 6 wherein pinch rollers are used to seal the edges of the members.
Claim 9
Independent Claim
22 words
A method as claimed in any of the preceding claims wherein the graphics on the members are deposited on their inner surfaces.
Claim 10
Dependent Claim
15 words
A portable electronic token manufactured by the method of any of Claims 1 to 8.
