ABSTRACT:
An individual conveyor equipped with controlled grippers arranged at a mutual uniform spacing from one another delivers the arriving printed products up to the starting region of a removal conveyor. The removal conveyor is driven at this starting region such as to move substantially in the same sense or direction as the individual conveyor at a product removal region thereof. This removal conveyor is equipped with controlled product removal grippers or gripper elements. The mouth openings of the grippers of the individual conveyor and the mouth openings of the product removal grippers of the removal conveyor are controlled in an opposite sense with respect to one another. To render the design of the removal conveyor less complex and to reduce the noise emission during operation thereof, the product removal grippers are secured at a uniform spacing from one another at a driven endless traction element. Each of the product removal grippers have a movable jaw and a fixed jaw. The movable jaws of the product removal grippers, in the open position thereof, are laterally shifted or pivoted away from the associated fixed jaw and pre-biased by a first resilient action in this open gripper position. In the closed position of the product removal grippers the movable jaws are directed essentially in the same direction as the associated fixed jaws and are pre-biased by a second resilient action. The second resilient action overcomes the first resilient action.
