摘要： The invention relates to a method for making standing folds in a material web and a knife folding machine (1) for producing such standing folds. The knife folding machine has at least two folding knives (2, 3), which are situated one opposite the other with respect to the material web (4). A folding channel (5) extends from the folding knives (2, 3) in the folding direction (F). In order to reduce the costs involved in resetting the knife folding machine (1) to other material webs (4) to be folded or at the end of a material web (4), a work transfer device (14) is provided, which, in an ejection mode, has a stop (24) which juts into the projection area of the standing folds (26) in the folding channel (5) in the folding direction (F). As a result of the work transfer device (14), the standing fold parcel (26) in the folding channel (5) is able to be ejected and to be further processed in normal fashion by following appliances, without waste being incurred.
