The invention relates to a device for processing fibre-reinforced plastic, more particularly for producing structural components for aircraft (2) or preforms for same, said device comprising at least two functional units (4), the functional units (4) comprising at least one feed unit (5) for feeding a laid fibre scrim web (6) and a processing unit (8) for processing the laid fibre scrim web (6), with a primary drive (9) for driving the laid fibre scrim web (6), with a control arrangement (10) for open-loop or closed-loop control of the primary drive (9). According to the invention the device (3) has at least one secondary drive (11) for driving the laid fibre scrim web (6), the device (3) has a force-measuring device (12) associated with the secondary drive (11), with a force sensor (13) for measuring a web tension in the laid fibre scrim web (6) by means of the control arrangement (10), the control arrangement (10) controls the secondary drive (11) in a feedback control routine, the feedback control routine comprises a secondary feedback circuit (14) to control the secondary drive (11), the control arrangement (10) in the feedback control routine supplies the web tension measured by the force-measuring device (12) associated with the secondary drive (11) as an actual value (15) to the secondary feedback circuit (14) and determines and sets a controlled variable (16) for the secondary drive (11) on the basis of the web tension in the secondary feedback circuit (14).
