Abstract
Abstract Apparatus for placing flexible packages in a rigid container incorporates an infeed chute and diverter gate system for directing packages into a rotatable load head in preselected fashion. After the load head is filled, the packages are released therefrom into an empty shipping container located below the load head. The apparatus incorporates a control system which activates the components of the system in preselected cyclic fashion to enable continuous packaging in a rapid manner. The apparatus is especially suitable for the handling of flexible packages of fluid products such as milk. A method of effecting continuous packaging is also described.
