A pneumatic bottle stop for a case packer is presented. Fundamentally, the bottle stop consists of a cylinder associated with each lane of a case packer. A piston of each cylinder extends into the lane for making contacting engagement with oncoming bottles or articles. The bottles compress the piston into the cylinder, expelling air therefrom through an adjustable orifice of an associated quick dump valve. The pistons are extended by the application of exhaust air derived from a head control cylinder when the piston of that cylinder is drawn to position skid bars in the head to receive oncoming bottles. A bleeder valve is provided such that the cylinders associated with each lane are maintained at atmospheric pressure after extension of the associated pistons.
