ABSTRACT:
A rotary knife apparatus for depositing filled pouches in preselected count stacks along a travelling product conveyor. The rotary knife apparatus includes a rotating disc valve intermediate negative and positive pressure sources on one side and a rotary knife hub on the other side. The rotating disc valve includes a plurality of arcuate slots and apertures which communicate with the negative and positive pressure sources and axial ports in the knife hub such that the knife hub holds and expels the filled pouches along defined segments of rotation of the knife hub. The rotating disc valve has a dynamically variable rotational speed relative to a rotational speed of the knife hub for changing a predetermined number of different angular drop-off points during a period of rotation of the knife hub to correspondingly change the preselected count of pouches in a stack.
