A pair of web pulling cylinders, particularly for use in printing machines, wherein a single-layer or multiple-layer web is conveyed between the cylinders which are pressed together. The cylinders are driven and are in driven connection through drive elements mounted on cylinder journals. If the web is deflected around one of the cylinders, a differential gear unit is provided to adapt the circumferential speeds of the cylinders to the thickness of the web being pulled.
