Form cylinder of a rotary printing press, in particular of an offset printing press

   
   

A form cylinder is provided with a circumferential surface which is convexly curved in the axial direction, such that the convex profile, determined by calculation, of the circumferential surface varies in such a way that the diameter of the form cylinder is largest in the axial center and smallest at the lateral edges.

Um cilindro do formulário é fornecido com uma superfície circunferencial que seja curvada convexly no sentido axial, tal que o perfil convexo, determinado pelo cálculo, da superfície circunferencial varia de tal maneira que o diâmetro do cilindro do formulário é o maior no centro axial e o menor nas bordas laterais.
