Abstract:
A jogger for a signature feeder having a hopper for receiving signatures at an upper end of the hopper and forming a stack of the signatures in a vertical direction starting at a lower end of the hopper, the jogger comprising:a back stop disposed at a first side of the hopper; a flexible jogging element disposed at a second side of the hopper opposite the first side; and an oscillating device in operative connection with the flexible jogging element configured to oscillate the flexible jogging element in a direction lateral to the vertical direction so as to periodically bend the flexible jogging element against the stack of the signatures and form a pushing zone and a vibrating zone below the pushing zone in the hopper, the signatures in the pushing zone being urged against the back stop by the flexible jogging element during oscillation so as to register the signatures as the stack is formed, the signatures in the vibrating zone being vibrated by the flexible jogging element during oscillation so as to improve the registration of the signatures in the stack.
