Abstract Device for feeding and receiving a continuous web which is intended for printing presses of the sheet-fed type These devices are defined in that they use mechani- cal and pneumatic members equipping the sheet-fed press for different functions, depending on whether the printing mode is of the sheet-fed or continuous-web type. In another embodiment of the invention, the toggle mechanism 14B (Figure 1) for operating the suction cups 13, its axle 14A and the axle of the levers of the toggle mechanism 14B make it possible, in sheet-fed printing, to take the sheet from the stack 9 or, in continuous-web printing, the suc- tion cups 13 being replaced by the movable suction tube 31 (Figure 2), to retract the web 24 in order to ensure its relaying-on between each printing cycle. A removable frame 34 (Figure 2) works jointly with the pneumatic re- laying-on devices and is located at the inlet of the press. A delivery table 45 of constant level is formed by a paral- lelogram, the weight of which is compensated by means of a spring 47. The device processes equally continuous webs 24 (Figure 2) for forms prefolded and perforated with "Caroll" holes or a continuous web 24A (Figure 9) on a reel 70 and rewound on a reel 79 after printing.
