Abstract: An offset rotary press comprises one single control device for changing the size on the one hand and for fixing and detaching the cylinders on the other. The press comprises, on each side of the frame, a longitudinal and a horizontal threaded bar screwed by its end into one of the movable side plates, a worm wheel for simultaneously rotating the two threaded bars and causing the two side plates to slide, and compression springs compressed between devices integral with the external ends of the respective horizontal bars and with supporting points affixed to the frame, in such a way as to exert, in the outward direction, a tractive force on each threaded bar and the corresponding side plate and to create the pressure between the blanket cylinder and the engraved cylinder.

Abstract: A device for the longitudinal cutting of webs comprises two hollow shafts, each bearing a blade, and supported on a respective spindle. One spindle is supported eccentrically in a frame so that its rotation sets the inter-axis spacing of the two shafts, whereby the blades may be engaged and disengaged in the radial sense. The same spindle is displaceable axially whereby the blades may be engaged and disengaged in the axial sense. Both operations are performed by means of one and the same handle. Means is also provided for displacing simultaneously both spindles in the axial directions in order to position the blades relative to the web.
