[origin: EP1894872A1] The folder has controlling cams controlling respective displacement of movable press points and sheet folding tucking blades in contact with cam followers that are in the form of rollers. A mask cam (36) has a collection operation mode in which the cam (36) neutralizes a hollow of the controlling cams and a straight operation mode in which the cam (36) does not interfere with the hollow. The cam (36) has arc shaped semi-cams (40) radially movable between retracted and extracted positions, where the cam (36) is in the operation modes when the semi-cams are in the positions, respectively.
