摘要

The roller train comprises a chassis (4) composed of two cheek webs connected by a hub. The hub ends support a lever arm (10) having a roller at each of its ends. Rotation of the lever arm is limited by an upper (13) and lower (13') stop against which the lever arm end is supported. Each stop has a tapped drilling in which a threaded element (16) can be screwed to be supported against the lever arm end in order to pivot it relative to its rotational axis.
