Abstract
A feeder device for removing folded or unfolded signatures from a stack of signatures in an adjacent signature magazine and feeding a production line with the signatures. The device includes a conveying rotor having an approximately circular circumference and being rotatable in a conveying direction. The conveying rotor includes a recess at the approximately circular circumference for holding a front edge, in the conveying direction, of a printed product removed from the stack of signatures. A conveying belt partially rests against the circumference of the conveying rotor, and is drivable in the same direction as the conveying rotor, and together with the conveying rotor forms a conveying gap through which the signatures are conveyed to the processing line. At least one synchronously driven separating element includes a control device comprising a pivotal control shaft arranged parallel to the rotational axis of the conveying rotor. At least one suction head is coupled to a vacuum source and attached to the pivotal control shaft for partially lifting a signature off the stack of signatures by applying a suctioning effect to the front edge of the signature to transfer the signature to the recess of the conveying rotor.
