  • Devices and methods for manufacturing packaging materials
    Patent number: 7347911
    Abstract: Devices and methods for inflating and sealing packaging pillows from a material web are shown for consistently producing high-quality packaging pillows. A web of material is advanced past an inflation nozzle, inflated with gas, and sealed closed by a sealing element. The temperature of the sealing element is monitored using a thermocouple connection and automatically adjusted using a closed-loop system. A sealing clamp parallel to the sealing element maintains two sheets of the web in contact through the sealing step. The inflation nozzle is provided with two inflation outlets: a first outlet inserting gas longitudinally into the web of material, and a second outlet inserting gas laterally into the material. Gas input is controlled with the use of relief valves to maintain pillow quality at all stages of production.
