Abstract
A gatherer stitcher includes an endless gatherer chain for gathering and transporting folded sheets astride the chain. The gatherer chain has chain roof segments and driving elements being adjustable in position. In an inactive position, a driving element that can be folded forms part of the roof of the gatherer chain and, in another, active position, projects out of the roof of the gatherer chain transversely relative to the conveying direction. The driving element can be driven by a control device. A method for adapting the endless gatherer chain to a format of a product is also provided.
