Endless belt running machine - has swivelling friction board with damping component, pref. of polyurethane foam

摘要

Running machine has an endless belt mounted on rollers. The upper portion of the belt runs over a friction board (37). This can be swivelled (on bearing (38)) and is supported at a distance from the bearing by one or more damping components (1). The board is connected to a deflecting roller (41) over which the lower portion (36a) of the belt (34) runs. The damping component pref. consists of an elastic roller made form polymer foam, esp. polyurethane foam.
