Abstract
An adjustment mechanism for a friction drive unit. To adjust the contact pressure between the friction wheel and a cooperating wheel of the friction drive unit, one of these wheels is mounted on a lever that is pivotable about a pivot axis. A cam that applies the contact pressure rests against the lever. The spacing of the cam relative to the pivot axis of the lever is variable.
