<p>PROBLEM TO BE SOLVED: To surely device a driving net even though friction resistance in increased at an adsorption part and a desorption part by attaching driving bars to a driving net, fixing each end of the driving bar to a driving chain and fitting a friction reduction means on each roller shaft. SOLUTION: The driving net 9 is wound around each of the rollers 4 and an adsorbent mat 5 is piled thereon. The driving chain 16 is wound around sprockets 15 at both ends of each shaft 3, and the driving bars 17 are attached on the driving net 9 in the width direction of the driving sheet 9 at regular intervals in the longitudinal direction, and both ends are fixed to respective driving chains 16. Also between the driving net 9 and each roller 4, between the roller 4 and the shaft, and between the sprocket 15 and the shaft, friction reduction means such as bearings are interposed. Thus, a driving force of the driving chain is transferred to the driving net uniformly over the entire width via the driving bar and even though the friction resistance at the adsorption part or the desorption part is increased, the driving net can be surely driven.</p> |
