In a spinning machine having a weighing device for receiving fiber tufts from a hopper thereof and for intermittently supplying a block of fiber tufts of a predetermined quantity to a subsequent process by repeated unit supply operations, the gauge between a lifting apron and an evener cylinder of the opening machine is reduced to a predetermined small gauge during a last period of each unit supply operation. Further the driving speed of the lifting apron is capable of selectively reducing during the above-mentioned last period and the supplying operation is continued until the quantity of fiber tufts accumulated in a weigh pan of the weighing mechanism becomes a predetermined final quantity for the unit supply operation.
