The apparatus of claim 9 wherein said first and second drivers are smaller than said second and third drivers. 11. The apparatus of claim 9 wherein at least one of said grippers is movable into and out of at least one intermediate position disposed between said first and second respective positions thereof. 12. The apparatus of claim 11 wherein each of said first and second rear grippers is movable into an intermediate position, whereby when a container is engaged with said first and second rear grippers disposed in said intermediate positions, the container is engageable with the filling spout without substantial tension on the container. 13. An apparatus useful for filling non-liquid material into a container, the container being releasably engageable with the apparatus, the apparatus having a framework that includes an upper portion, a base, a front end and a rear end, and at least one filling spout associated with the upper portion, the apparatus comprising: first and second front grippers associated with the framework, each said front gripper being releasably engageable with a different portion of the container;first and second rear grippers associated with the framework, each said rear gripper being releasably engageable with a different portion of the container, said first and second rear grippers being linearly aligned with said first and second front grippers, respectively;first and second power-operated drivers associated with said first and second rear grippers, respectively, said first and second power-operated drivers capable of allowing the non-manual lateral movement of all of said grippers between at least two positions,wherein said first and second power-operated drivers are capable of moving said first and second rear grippers between a rearward home position and a forward position, respectively, and said first and second rear grippers are capable of pushing said first and second front grippers from a home position to a forward position, respectively; anda first dragger connecting said first front and rear grippers and a second dragger connecting said second front and rear grippers, said first and second draggers allowing said first and second rear grippers to pull said first and second front grippers from said forward to said home positions thereof, respectively. 14.
