there is no arma a obtaining printing that The invention .Tdes'cribed differs/from known cylinder printing ,presses with; automatic sheet' feederskin thatiin's ich machiristhe paper pile is situated inside themachine, so thatthe pile greatly hinders the accessibility to the machine, to the form, andtotheinlting parts.
