In a method for synchronizing drive units, a target value of the speed of each drive unit of a plurality of drive units speed is computed by determining the product of a maximum speed of the drive unit, a unit-dependent normalized ratio value of the drive unit, and a synchronization factor which is identical for all drive units. The ratio value defines the relative speeds of the individual drive units. Changing the synchronization factor causes synchronous speed changes of the drive units. As a result, a lasting synchronization can be realized across the entire speed spectrum.

A plastics processing machine for producing fiber-containing thermoplastics includes an extruder, and a scale assembly having a weighing plate for determining an amount of fiber to be supplied to the extruder. A fiber feeding device supplies fibers from a take-off unit into the extruder and includes a first fiber guide unit, which is securely fixed to the weighing plate, for removing the fibers from the take-off unit, and a second fiber guide unit which is decoupled from the weighing plate and so constructed as to route the fibers between the first and second guide units in a substantially perpendicular relationship to a gravitational force.
