Abstract
A folding device for an automatic sewing machine has a vacuum holding device for a sword. This measure serves to ensure a perfect position of the sword relative to an outer frame of the folding device during creasing of a workpiece. A suction plate provided for this purpose is pivotable relative to the outer frame in a direction away from the sword. This serves to allow very precise creasing to take place.
