Abstract (en)
An electric stapler (11) is provided with current at levels which would result in marginal operation of the stapler (11), but which would be sufficient to operate the stapler (11) if the load were averaged over a cycle of operation. A flywheel is added to the stapler (11) and builds momentum during an early part of the cycle of operation. When the load on the stapler (11) increases during a later part of the cycle of operation, the flywheel is decelerated, resulting in successful operation of the stapler (11). <IMAGE>
