The chopper device is provided with an elongated opening having a mouthpiece below the conveying path therefor. An upwardly and downwardly movable chopper blade lowers when the signature is stopper at a predetermined position and forces the signature into the opening. A pair of rollers is provided below the opening in order to grip the signature forced into the opening by the chopper blade nd deliver it to a delivery conveyor. Brushes are provided on both sides of the opening thereabove so as to slidably hold both sides of the signature when the signature is lowered by the rollers through the opening. Such an arrangement permits both side edges of the signature which has been released from the condition where it is held by the conveying belt to enter into the opening while sliding on the brushes. | |
