摘要

Provided by the invention is a buckle-plate folding station including a first folding roller and two further contra-rotating fold-forming rollers and an adjustable buckle-plate folding unit. The intention of the invention is to provide a buckle-plate folding station enabling the point in time of fold formation to be determined. For this purpose means for detecting sheet infeed are provided in the buckle-plate folding station. The buckle-plate folding station further comprises means for detecting the deflection of at least one of the fold-forming rollers in forming the fold. Means for determining the sheet length fed between sheet infeed and formation of the fold are also provided.
