Abstract: A grouper apparatus for a packaging machine and methods of grouping items for packaging are provided. The grouper apparatus may have at least two container guides for defining lanes for receiving containers, at least one of the at least two container guides being movable, and at least one timing screw. The at least one timing screw may be positioned at least one of: between the at least two container guides; and coaxial with a corresponding one of the at least two container guides. The at least one timing screw may be adapted to receive and advance at least one lane of containers on either side thereof. A controller may be provided for controlling revolution of the at least one timing screw to provide at least one of a desired output grouping and a desired output rate of the containers.
