Abstract
A folder includes a cut-off cylinder, etc. for cutting a web into sheets; a group of cylinders for folding each sheet into a signature in accordance with the selected folding specifications; and a conveyer apparatus, a fan wheel, a delivery conveyer, etc. for conveying signatures. In the folder, a cutting blade, etc. are disposed on the upstream side of the cut-off cylinder with respect to the feed direction of the web. When the folding specifications of signatures are changed or when the width of the web is changed, a control device operates the cutting blade to cut the web, and controls the feed of the web in such a manner that only a cut portion of the web present on the downstream side of the cut blade with respect to the feed direction is conveyed to the delivery conveyer.
