ABSTRACT:
A sealing wheel has a pneumatic tire with means whereby the flexure of the tire may be altered to compensate for dimensional differences in associated parts so that a required sealing pressure may be maintained. In one embodiment, a plurality of sealing wheels are mounted on a common shaft, the tire of each wheel being coupled with a source of compressed air, the air line for each tire having a pressure regulator so that the several tires may be regulated independently of each other, or coupled with a common source so that all tires may be regulated together. In one embodiment of the invention there may be a partial filling of the tire with liquid of a type which will bring about a more even distribution of heat where there is heat sealing.
