Duplicating stencil

摘要

A duplicating stencil has its heading strip in the form of two separate regions separated by a perforation line. The holes on one region have a different arrangement from those on the other regions, so that tearing along the perforation line allows one region to be separated from the rest of the stencil and to leave the holes of the remaining region as the effective mounting holes. A single image field and a single top edge guide line apply for all of the heading strip regions.
