<p>The switchback device (10) has two switchback portions (20R,20L) for inverting the conveying path of paper-like materials and a detour conveying path (8). The switchback portions (20R,20L) receive paper-like materials in the nip between the switchback rollers (23R,23L) and the pinch rollers (24R,24L), clamp the paper-like materials, decelerate, stop, and accelerate them in the opposite direction in a clamping state, thereby switch back the paper-like materials. The stopping time of paper-like materials in the switchback portions (20R,20L) is changed according to the length of the paper-like materials in the conveying direction. <IMAGE></p> |
