摘要：
A stapling machine particularly adapted to form and drive staples into work when there is limited clearance between the stapling machine and other parts of the work, such as in stapling a picture frame, in which the staple is supported by a disappearing arbor as it initially moves toward the work and is then supported by a second arbor, which is preferably retractable itself, as the staple is being driven into the work.
