Abstract
A rotary stamp mechanism includes a drive wheel with a curved stamp holding housing held thereon by a sheet metal band to enable replacement and adjustment of the stamp housing. A stamping sequence is selected by a machine operator and the leading edge of the next succeeding copy sheet triggers rotation of the drive wheel and during one complete revolution of the drive wheel the copy sheet is stamped with a desired logo. A pawl on the drive wheel is lifted by the copy sheet for stamping purposes and gravity returns the pawl to its home position which in turn stops the drive wheel in its initial position for succeeding stamping.
