ABSTRACT:
Packaging apparatus for packaging units in flexible sheet material with the units spaced longitudinally in a tube formed of a web of the material and with the tube sealed together between successive units. 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 apparatus also includes an electronic pulse counter or encoder driven at a speed proportional to the speed of the wheel to effect the release of a sealing unit in the event the passage of a unit to be packaged is not sensed by a photoelectric sensor when packaging the units in unprinted sheet material, or to control the placement of units to be packaged on a web of the material having registration marks preprinted thereon.
