Abstract: The folding station of a rotary printing press has a folding cylinder on which the printed paper web is cut into sections. Mounted opposite the folding cylinder, a jaw cylinder has cut in its surface several jaw cavities each extending parallel to the jaw cylinder axis for receiving the midpart of the web section as the same is inserted therein by a folding blade on the folding cylinder. Each jaw cavity has mounted therein a series of fixed jaw parts and a series of movable jaw parts, the latter being jointly movable toward and away from the former for engaging and folding the midpart of the web section. The two outmost ones of the movable jaw parts are positioned closer to the fixed jaw parts than are the other, medial movable jaw parts, in order to more firmly engage the margins of the web section without causing ink offset between the contacting surfaces of the image areas of the web section.

Abstract: A shock absorbing unit includes a fixation plate superposed and detachably fixed on the outer surface of an internal component. An erect plate continuously extends from the fixation plate so as to stand on the outer surface of the internal component. A pair of elastic leaves are superposed and adhered on front and back sides of the erect plate. The elastic leaves serve to absorb an impact or vibration. The internal component can be protected or separated from the impact or vibration. Moreover, the shock absorbing unit can be attached to or detached from the internal component as a whole in a relatively facilitated manner. When the elastic leaves are to be replaced with new ones, the shock absorbing unit as a whole may be replaced with a new one without unsticking the elastic leaves from the erect plate.
