Abstract

PURPOSE: To slow down as well as to smooth the up-and-down movement of movable rollers around which a plate-shaped flexible member is hung by providing those rollers with gears, attaching to a frame a rack that engages always with the gears, and utilizing the engagement resistance between the both.
CONSTITUTION: If, for some reasons, the feed rate of a plate-shaped flexible member 27 is lowered at the preceeding stage side or if the rate of a plate- shaped flexible member 27 is increased at the suceeding stage side, the tension of the flexible member 27 is increased. As a result, each movable roller 12 to 14 is energized upward, and moves up together with a connecting board 15. At this time, gears 22 and 23 are fixed to shafts 12A and 14A which are connected together by the connecting board 15. These gears 22 and 23 are engaged with a rack 10, and the both gears 22 and 23 are constituted in such a way that they roll in the same direction and at the same speed owing to an action between sprocket wheels, 24 and 25, and chains 26. Thus, the connecting board 15 is moved upward slowly.
