Abstract: A sheet feeder for feeding printed sheets to a conveying device, with a gripper drum that has at least one gripper for removing the printed sheets one at a time from a stack; a pocket is permanently mounted essentially in the peripheral area of the gripper drum wherein the printed sheets are aligned against a stop with the fold forward and set down on the conveying device with reversal of direction; and with a decelerating device for slowing the speed of the printed sheets downstream towards the stop. The decelerating device has at least one secondary stop, which rotates in the same direction as the gripper drum, has a slower speed than the gripper drum for slowing down the printed sheets, and on which the printed sheets are slowed down upstream of the stop.

Abstract: An analog electronic circuit is proposed that e.g. computes the symbol likelihoods for PAM or QAM signal constellations. The circuit has at least one set of M transistors connected to a common current source. A multiplier/adder generates the voltages to be applied to the transistors from a value y and a set of M expected values in such a way that the currents through the transistors correspond to the likelihood that the value y corresponds to the expected values. The circuit can be used for signal demodulation and various other applications.

Abstract: A folding device for signatures includes a saddle-shaped folding sword having an upright folding edge and an inside guide element below the upright folding edge on which the signatures are folded while passing through the folding device. An outside folding element follows and operates jointly with the inside guide element for folding the signatures.

Abstract: A method for binding graphic products formed of folded signatures securely joined along a folded back end of the signatures includes providing at least one flexible tab and providing each signature, respectively, with at least one slit in a region of a fold. The tab is pulled into the slit for joining the signatures.

Abstract: Delivery device for removing printed products which straddle a saddle-shaped support of a conveying arrangement with the aid of circulating carriers. A gripping device comprises two rotating gripping members respectively positioned on the circumference of a rotating support between which the printed products are gripped and lifted off the conveying arrangement. Preferably, the gripping members have a curved outer shell surface that forms an essentially circular contour together with an outer shell surface of a support. The printed products are pulled off horizontally with initially high speed from the conveying arrangement and then transferred vertically to another conveying arrangement. The collision with the subsequent printed product is avoided even with high production capacity.

Abstract: The extension arm is used for removing printed products, which are conveyed with the aid of circulating carriers, such that they straddle a saddle-shaped support of a conveying arrangement. With the aid of a gripping device, the printed products are gripped and then lifted off the conveying arrangement. The gripping device comprises two rotating gripping members, which are respectively positioned on the circumference of an also rotating support and between which the printed products are gripped and removed. The gripping members preferably have a curved outer shell surface that forms an essentially circular contour together with an outer shell surface of a support. The printed products can be pulled off in horizontal direction and with initially high speed from the conveying arrangement and can then be transferred with a vertical movement to another conveying arrangement. Thus, a collision with the subsequent printed product can be avoided even with a high production capacity.
