  • Method and apparatus of producing sheet wrapping body
    Patent number: 5740661
    Abstract: In a sheet wrapping body producing apparatus, an oxygen absorbing strip sheet supplied from an oxygen absorbing sheet supplying shaft is cut out by a first rotary die cut unit to make an oxygen absorbing sheet tip. The tip is transported in such a manner to prevent the misalignment by a delivery drum unit and a first transportation belt unit. During the transportation, a breathing layer strip sheet is supplied on a transporting surface of the first transportation belt unit, on which the oxygen absorbing sheet tip is placed. Also, a strip cover film is placed on the oxygen absorbing sheet tip. Then, a rotary seal unit seals the breathing layer strip sheet and strip cover film, and the sealed portion is cut by a second rotary die cut unit. Accordingly, a sheet wrapping body can be produced at high speeds.
