2. Description of the Related Art A sealing device in a packaging device intermittently conveys a tubular film containing articles to be packaged, for example, at predetermined intervals, and holds a holding body above and below the film. Once the film transport is stopped, the position between the objects to be packaged is sandwiched from outside the film by this holding body, and the film is welded by the heat of the heater at the tip surface of the holding body. The space between the objects is sequentially sealed, and, for example, the middle part of the heat seal position is further cut off and intermittently conveyed so that the packaging bags containing the objects to be packaged are sequentially carried out.

[0003] However, even if it is possible to control such that the interval between the objects to be packaged is always constant and the intermediate position between the objects to be packaged and the film is always sandwiched and heat-sealed, If there is dust or the like in the position to be packaged, there is a risk of causing poor heat sealing.

[0004] That is, for example, to be packaged is out debris such as mushrooms
If it is easy casting, you may like debris and soil strips and stones with part of the mushroom in the film exits, without sandwiching the even mushroom itself by holding member chewing such debris with film If heat sealing is applied by sandwiching the film, the heat welding between the films will be insufficient, and the welding will peel off after bag making,
Alternatively, there is a possibility that sealing failure such as no welding is caused.

[0005] Further, the heat seal portion also serves as a cutting position, and if debris is caught in this portion, defective cutting, breakage and wear of the cutting blade may be accelerated.

An object of the present invention is to improve such a conventional sealing device and to provide an extremely innovative sealing device in a packaging device which can solve the above-mentioned problem of biting.
