ABSTRACT:
Apparatus for transversely sealing a wrapping tube includes opposed sealing tools movable in unison linearly along an operating path having a beginning and an end while sealing a wrapping tube. The tools return from the end of the operating path to the beginning thereof by moving along arcuate return paths. Crank mechanisms for so moving the tools include cam tracks and cooperating cam followers. The cam followers are urged against the cam tracks under the influence of centrifugal force during movement of the tools along the return paths.
