  • Device for embedding a metallic antenna wire in plastic sheet
    Patent number: 4196038
    Abstract: A device for embedding a metallic antenna wire which can be heated in a sheet of a thermoplastic material. The device has a mounting table for mounting the sheet of thermoplastic material thereon, a guide head positioned above the table and movable in a predetermined pattern in a plane parallel to the surface of said table, a pressure means on the guide head for pressing the wire into the thermoplastic sheet as the guide head moves parallel to the table, wire supplying means on the guide head supplying the wire to the pressure means, and heating means on the guide head along the path of the wire from the wire supplying means to the pressure means for heating the wire to a temperature which is sufficient, when the pressure means presses the heated wire onto the sheet, to plasticize the sheet sufficiently that the pressure means embeds the wire in the sheet.
