The apparatus includes a rotary sealing wheel carrying a series of sealing assemblies for sealing the tube, the sealing assemblies being uncoupled from the wheel and held at a hold position for again being released in timed relation to movement of the tube for sealing the tube between successive units. The sealing assemblies are releasably coupled to opposite sides of the wheel, and in accordance with this invention an arrangement is provided for simultaneously uncoupling and coupling the sealing assemblies from both sides of the wheel.
