Abstract: A method and apparatus are disclosed for automatically delivering discrete pieces of stationery, particularly envelopes, serially at a controlled rate from a stack of stationery into a programmable printing machine such as an automatic or a manual typewriter. Simultaneously, discrete pieces of stationery which have been printed by the typewriter are automatically fed back into the stack at the same rate at which they were delivered therefrom. The speed of operation of this automatic stationery handling apparatus is automatically coordinated to the speed at which discrete pieces of stationary can be processed by the programmable typewriter.
