Abstract
The present invention relates to a control method in the feeding of plate shaped workpieces to a work station, comprising feeding of the workpiece (8) to a control station (1) at which control station (1) it is controlled that the desired number of workpieces (8) are fed to the work station (7), whereby weighing is performed at said control station (1) by at least one electronic weighing unit (3) that transmits signals to a control unit (6) arranged to signal for the feeding of the workpiece (8) to the work station (7) when the transmitted weight signal lies within a predetermined set point range, wherein said weighing unit (3) is kept fixed on top of a fixing structure (4) and in that control takes place directly at the control station (1) before initiating moving of the workpiece (8) to the work station (7), in order to give reliable moving of a single workpiece (8) at the time in the work station (7).
