An apparatus for controlling the feeding of cases into an article handling machine from a moving conveyor which feeds a continuous line of cases thereto. The apparatus includes an abutment carried in the path of flow of the cases. The abutment extends above the conveyor for engaging a front end of a first case of said line of cases stopping the forward movement of the cases on the conveyor. A movable post is carried below the front end of the case and is selectively raised for lifting the front end of the case over the abutment so that the case can be indexed forwardly on the conveyor and into the article handling machine.
