ABSTRACT:
Folded articles, such as paper napkins, handkerchiefs, and the like are puced of an intially continuous web or sheet material which is moved into a folding machine in a feed advance direction at a controllable feed-in speed. The sheet material may be folded once lengthwise around the feed advance direction before it is cut by a cutter operating at equal time intervals. The cut sheet material sections are then accelerated and after the acceleration they are folded at least once crosswise around a direction perpendicularly to the feed advance direction, whereby the cut sections travel at a constant speed during the crosswise folding and subsequent stacking. The feed-in speed is kept constant as long as articles of a given size are being produced. When the article size is to be changed, the feed-in speed is accordingly changed. The folding machine is equipped with a speed controllable sheet feeding device upstream of the cutter and with a sheet accelerating device downstream of the cutter as viewed in the feed advance direction.
