  • Method of enveloping articles with thermoplastic strip material
    Patent number: 4268469
    Abstract: A method of enveloping an electrical component in a thermoplastic material is provided. The facing surfaces of two parallel spaced strips of a closed-cell cellular thermoplastic material are heated to a temperature above the softening or melting temperature of such thermoplastic material while maintaining the temperature of the remainder of each strip below such softening or melting temperature. In this condition the two strips and the electrical component are introduced into a mould with the component between the heated surfaces; and the mould is closed about the strips to plastically deform the same and to encase the component therebetween.
