Abstract: An infeed conveyor advances side-by-side lines of rectangular cartons, such as six pack cartons, into a grid structure from which the cartons are to be dropped, in two groups of four cartons each, into two upwardly open packing cases. The grid structure includes means for detecting the presence of eight cartons therein, and a line brake is set in response to the detecting means to hold back cartons on the infeed conveyor. The grid structure includes a fixed frame in which two shifting carriage portions are slidably mounted for movement through different displacements in the downstream direction, and each carriage portion carries one of said carton groups. After being so shifted the two carton groups are dropped downwardly through doors in these carriage portions and into the upwardly open packing cases.
