ABSTRACT:
A magnet strip extends along one generator of a printing drum of a rotary stencil printing device. A clamp strip, made of a material which is magnetically attractable, is hinged to said printing drum along a line substantially parallel to said one generator thereof, near one side of said magnet strip, so that said clamp strip can be pivoted either so as to lie against and along said magnet strip, with a leading edge of a stencil master for stencil printing interposed therebetween so as to clamp the leading edge of the stencil master to the printing drum, or so as to be removed from said magnet strip so as to release the stencil master. Thereby the stencil master can be conveniently retained to the printing drum in a manner which is suitable for automation, and does not require any reinforced lug portion along the leading edge of the stencil master.
