ABSTRACT:
A coupling bar, to which a leading portion of a web has been secured, is engageable with a moving belt for transporting the web. To attach the coupling bar to the moving belt, gripper members of the coupling bar are positioned to straddle a reduced width section of the moving belt. The gripper members are spaced apart a distance greater than the width of the reduced section, but less than the width of a belt section which follows the reduced section. Accordingly, after the reduced width section of the moving belt is advanced from between the gripper members, the following wider section will be moved into edgewise engagement with them. By this means, the coupling bar is attached to the moving belt without the belt having to be stopped or manipulated.
