摘要

The sectioned door panel is composed of separate panels (1) which are linked together, with running rollers (2) to ride in side guide rails. The rollers (2) are each fitted to an adjustable holder (3) at right angles to the door panel plane. The roller holder (3) has a roller pedestal (4) and a setting bolt (5), which rotates in a drilling (6) in the pedestal (4), and is locked in position. The axis (10) of the roller (2) fits into an eccentric drilling (11) in the setting bolt (5), which is parallel to the bolt axis and off-center.
