PURPOSE:To easily mount a paper, by a method wherein a driving motor is turned OFF when a gripper gripping a continuous form paper comes to a fixed position, and paper-feeding chains are traveled under inertia by a fixed distance, the chains are stopped by dynamic braking, and the paper is engaged with a paper-feeding tractor. CONSTITUTION:The paper-feeding chains 7, 8 simultaneously driven by the motor 6 are provided on the outside of the paper-feeding tractor 1, and the gripper 9 is bridgingly provided between the chains 7, 8. The continuous form paper 12 is provided with holes 13 on both sides thereof, and is fed in the direction of an arrow while being gripped by the gripper 9. When the gripper 9 passes over the tractor 1 and the front end of a reflecting plate 11 is detected by a photo-electric detector 10, the motor 6 is turned OFF, after which the chains 7, 8 travel under intertia. When the rear end of the reflecting plate 11 is detected, the chains 7, 8 are stopped by dynamic braking, resulting in that the feed holes 13 of the paper 12 are located at positions directly above pins 4 of the tractor 1. Accordingly, mounting of the paper 1 is completed by rotating paper-lifting bars 14, 15. |
