Abstract:
PCT No. PCT/DE96/00702 Sec. 371 Date Dec. 16, 1997 Sec. 102(e) Date Dec. 16, 1997 PCT Filed Apr. 23, 1996 PCT Pub. No. WO97/00384 PCT Pub. Date Jan. 3, 1997A roller with controllable sag is provided with a revolving hollow roller and a non-rotating crosshead that crosses the hollow roller along its length and on which the hollow roller is supported by a series of supporting elements that are actuated by a pressure medium. Separate supply lines (13) lead to the supporting element and open out into a collection head (40) at the end (10') of the crosshead, to which the outer connection lines (53) are connected. The connection head (40) comprises a double-disc rotary slide valve (50) by which the lines (13, 53) can be interrupted and which in the closed state can be separated at a separation surface (47). The individual discs (51, 52) of the double disc rotary slide valve (50) keep both the supply lines (13) and connection lines (53) closed, thus facilitating replacement of the roller as and when required.
