A method and apparatus for producing and/or machining panels. The apparatus includes a transport device for transporting a panel along a transport path and a machining device for machining the panel as it moves via the transport device. The transport device includes a plurality of positioning devices arranged one behind the other and spaced apart by a distance along the transport path. Each positioning device includes upper and lower abutment mechanisms arranged opposite one another and on opposite sides of a panel plane, and being spaced apart by a distance. An adjusting device is used for setting the distance between the upper and lower abutment mechanisms. An actuating arrangement is structured and arranged to actuate the adjusting device of at least two of the plurality of positioning devices. An arrangement is used for independently adjusting each of the upper and lower abutment mechanisms of at least one of the plurality of positioning devices.
