Abstract
A sheet metal folder includes a movable fold bar, an actuator to move
the movable fold bar and a sheet position monitor which monitors the position of the
folded portion of a sheet being folded. During folding, a controller moves the fold
bar to a first fold position and retreats the fold bar to a position in which the sheet is
no longer contacted by the fold bar. The current position of the sheet is then
registered. A second fold position is calculated using the difference between the first
fold position of the fold bar and the registered position. The fold bar is then moved
to the second fold position. The sheet position monitor may involve a detector
detecting the presence of a folded part of the sheet against the fold bar, with the
current position of the sheet after the fold bar is retreated being registered by
registering the position of the fold bar immediately the sheet no longer resides
against the fold bar.
