Abstract:
1. A method of manufacturing a venting device for a tamper resistant enclosure, comprising: providing two strips of coverlay material each with a layer of thermally activated adhesive, the coverlay material being gas-impermeable; providing a length of gas-permeable semisolid material interposed between the two strips and extending from one end of the strips to the other end of the strips; wherein the gas-permeable semi-solid material is a fibrous yarn laminating the two strips together in a sandwich with the gas-permeable semisolid material in between at elevated temperature and pressure for a predetermined period of time, so as to form a vent channel between the strips, the vent channel allowing a gas to flow therethrough from the one end of the strips to the other end of the strips; and the length of the gas-permeable semisolid material is guided along a zig-zag path between one end of the strips and the other end of the strips.
