A folder has at least two transverse paper cutters, each with folding blades for use with a fold jaw cylinder for sheeting and folding paper web coming from a printing press and forwarding the sheets produced to a delivery station. The one or the other transverse cutter (as put into operation on makeready) is used for producing sheet sizes answering to the full or half of the plate cylinder circumference of the printing press. The fold jaw cylinder has tool take-up or fixing positions spaced about its circumference with a spacing equal to half the smaller sheet size to be processed. The fold jaw cylinder is designed to have fixed thereon fold jaws with a spacing therebetween equal to the spacing between the folding blades of the one or the other cutter used at the time and to have fixed thereon scissor or shear cutting knives, running out past its circumference radially and spaced to the back of the jaws (in the direction of running) by half the jaw-to-jaw distance. There is furthermore a knife cylinder between the cutters and the delivery station. This knife cylinder has a circumference at least equal to the largest paper size and is designed to take up knives for use with knives on the fold jaw cylinder.
In a folder adapted for two different cutting formats, one format cutting sheets of one half plate cylinder circumference and the second format cutting sheets of full plate cylinder circumference, said folder comprising a fold jaw cylinder, at least two transverse paper cutters circumferentially spaced about said folding jaw cylinder and located in a transverse paper cutting station, each transverse cutter including a folding blade cylinder having at least one folding blade, each folding blade cylinder being adapted to cooperate with said fold jaw cylinder to fold a sheet cut from a web by one of said paper cutters and for forwarding the sheets to a delivery station, means for making one of said transverse paper cutters active one at a time, said fold jaw cylinder having tool support points circumferentially disposed in equal spaced apart relationship corresponding to one half the smallest paper size to be cut, fold jaws removably positioned in certain of said tool support points cooperating with the folding blades of the active transverse cutter, spaced-apart scissor cutting blades for cutting a paper web into cut sheets some of which are removably positioned in tool support points alternating with said fold jaws, said scissor cutting blades running radially ouutwardly from said fold jaw cylinder, and a knife cylinder for cutting said paper web in cooperation with said scissor cutting blades of said fold jaw cylinder to provide a smooth cut to said cut sheets, said knife cylinder being disposed between said transverse paper cutting station and said delivery station, the circumference of said paper knife cylinder being equal to at least the greatest paper size to which said web is to be cut, said knife cylinder being adapted to have removably positioned thereon, with the same spacing of said scissor cutting blades of said fold jaw cylinder, further scissor cutting blades for use in cooperation with said scissor cutting blades of said fold jaw cylinder, whereby the removable fold jaws and scissor cutting blades of the fold jaw cylinder and the removable scissor cutting blades of the knife cylinder are removed or installed to cooperate with the active transverse paper cutter.
