Abstract: 621,939. Inserting supplements into signatures; feeding sheets. BEWEG AKT.-GES. Feb. 27, 1947, No. 5719. Convention date, March 1, 1946. [Class 100 (i)] In a machine for inserting supplements into signatures the signatures are fed from a pile A, Fig. 1, and forwarded to an intermittently-moving conveyer 4 in overlapped condition past a series of opening-out devices which open out the pages of the signatures successively until the position for receiving the supplements is reached, and then the opened-out signature is maintained in position by a guide 7 while an insert 10 is fed from a pile C by sheet-feed mechanism similar to that for feeding the signatures. A pusher delivery device finally forwards the completed product to delivery belts 9. The signatures 2, Figs. 1 and 2, are fed from an inclined pile 39 by an oscillating suction device 40, and are pulled in an upward direction by grippers 36 of a gripper cylinder 30, from which they pass over a guide 5 to feed rollers 52, 53 which feed them to an inclined table 1 where a reciprocating pusher 3 advances them to intermittently moving conveyer tapes 4 which are driven by a Geneva motion device of which the driving member has three pins which cooperate with six grooves in the driven member. The stack 39 is advanced to feed-position by an intermittently-moved band 63, and the pressure of the forward end of the pile 39 on the sucker 40 is relieved by an intermittently-rotated wheel 74 fitted with radial fins 741 which are moved counterclockwise to keep back the upper signatures. Brushes 84 act on the signatures to prevent double feed, and a finger 85 controls the top of the A pile. The band 63 is adjustable by means of a screw 88 to allow for signatures of different sizes, and the opening-out mechanism is also adjustable for signatures of different sizes. The signatures 2 are advanced along the table 1 in overlapped position, and while being advanced the pages of the signature are in succession opened out by the action of suction devices 5, Fig. 12, which are mounted on oscillating levers which move the suckers 5 on to the pages of the signature in succession and then the reciprocating rod 143 on which the suckers are mounted is moved in the direction of movement of the conveyer belts 4 and the raised edge of the page is maintained in open condition by a guide-plate 6. In all there are eight suction devices 5 shown but the suction conduits leading to the devices, in which the air pressure is controlled by an oscillating valve, are fitted with cocks which permit the cutting out of some of the suction devices if there are less than eight pages which require to be opened out. A stripping device 158 moves with each suction device 5 so as to prevent the opening out of more than one page at a time by each suction device. In Fig. 12, only five of the suction devices are shown, but in Fig. 1 the position of eight devices is shown. The means for delivering the final product after a supplement has been fed from the stack C into the opened-out signature 2, which is maintained in open condition by a guide 7, is shown in Fig. 18, and comprises a reciprocating pusher 8 which is moved in a direction longitudinally of the table 1 by an oscillating lever 184 operated by a cam on the control shaft 12. On the return of the pusher device 8 it is oscillated so as to move below the table so that the succeeding opened-out signature can pass over it before it is again raised to operative position. The final products are delivered by belts 9, Fig. 1.
