Abstract
A printing machine for applying marks at specified locations on a moving web. The machine has specific utility in check or document signing applications where a number of forms are successively signed by a signature stamp. In accordance with a preferred embodiment of the invention the machine has one motor for driving a web of paper to a print station and a second motor for activating a stamp by rotating the stamp into contact with the web. The motors are individually energizable under control of a programmable controller. By coordinating the times and duration of motor energization the spacing between successive marks can be varied over a wide range of values. The flexibility in print spacing allows the printing machine to be used in conjunction with the processing stations such as word processing and the like.
