  • Cart movement track

    Abstract: A cart is movably engaged with a flow control track by a pair of different height cam followers. An end track segment between parallel side leg track segments of the track contains inner and outer end channels. An intermediate wall in the end track segment forms the outer and inner end channels and cooperates with the height of the cam followers to direct one cam follower on each cart into one of the inner and outer end tracks and the other cam follower on the cart into the other of the inner and outer end channels to smoothly control the movement of the cart around the end segment between the ends of the first and second side leg track segments.
