ABSTRACT:
A folding triangle made of sheet metal is formed with a central opening through which a deformation roller, for example having teeth for perforation, or an edge for creasing of the paper web traveling over the folding triangle, is secured. A counter roller suitably shaped with respect to the deformation roller is located above the folding triangle, to be engaged by the deformation roller. The rollers are longitudinally as well as height adjustable. The apparatus is preferably associated with paper webs traveling through a printing machine.
