<p>A subjection mechanism defines a trajectory path with four spaced apart points. One of the points is for receiving the package from an endless conveyer, another point or filling the package, and another point for evacuating the filled package. A pair of subjection clamps keeps the package open or closed, when the package is moved from reception to filling positions or from filling to evacuation positions. The mechanism further includes a pair of telescoping tubular carriages movable between package open and package closed positions.</p> |
