However, in all of the above-mentioned conventional heat sealing apparatuses, the distance H is adjusted almost by relying on the operator's intuition by manually operating an adjusting bolt or a cylinder mechanism. In addition, it is extremely difficult to adjust the clearance (clearance) of the thickness of the packaging film, which is several μ to several tens μ, with sufficient precision, and it takes a considerable amount of time to adjust the clearance. Even after adjusting the distance, it is necessary to repeat the fine adjustment by monitoring the actual dimensions and the condition of the horizontal seal while continuing the trial sealing for a while. During that time, the packaging film and filling material (material to be packaged) However, there is also the uneconomical disadvantage that a considerable amount is wasted.
