A movable wall system used to divide a large room into small rooms has a train of wall panels connected by hinges. The system includes a mechanism for automatically flattening the panels when moving them into their fully extended position by applying a momentary backward force to the panels as the panels approach the extended position. The system also includes a mechanism for breaking the panels to permit easy retraction and stacking of the panels. A rotatable cam positioned on the overhead track of the wall system forces a hinge of two connected panels outward so that the panels will stack when a reversing force is applied to the panels.
