A parallel-folding device for a folding machine capable of automatically performing the position control of a brush guide according to folding specifications under the operation of the machine. A first gripper cylinder (26), an upper second gripper cylinder (27), and a lower second gripper cylinder (28) are arranged with their peripheral surfaces oppositely brought into contact with each other, a signature is parallel-double folded by the upper second gripper cylinder or the gripper claws (36a to 36d, 38b, 38d) of the upper second gripper cylinder and the lower second gripper cylinder in association with the knife of the first gripper cylinder, and brush guides (41) are attached onto the peripheral surface of the first gripper cylinder at positions on the upstream side of opposed contact points between the first gripper cylinder and the upper second gripper cylinder and between the first gripper cylinder and the lower second gripper cylinder in the rotating direction. The brush guides are installed so as to be moved close to and apart from the peripheral surface of the first gripper cylinder by a pair of right and left drive parts (44b, 44a) formed of screw shafts (51a, 51b) and brackets (58a, 58b) driven by motors (47a, 47b) with rotary encoders (55a, 55b).
