Abstract
Abstract Mechanism for forming gusset folds in container wrappers which are formed about a moving group of containers. The gusset folds are formed in gusset panels and are employed to stabilize the position of the endmost containers of the wrapped group, and are formed as the wrapper blank moving with the group is wrapped therearound. The mechanism includes a cam and cam follower mechanism so configured that the tip of the folding member at all times engages a fold line of the gusset panel of the wrapper blank, irrespective of the movement of the gusset panel during the folding of same.
