A production line for manufacturing extruded plates, comprises a conveyor for conveying a semifinished product, an edge cutting device for cutting off an edge area of the semifinished product to present a plate-shaped endless base profile, and a separating device for separating individual plates from the endless base profile. A distance (D) between the separating device and the edge cutting device in the conveying direction is dimensioned such that, between an average temperature T1 of the semifinished product during cutting of the edge area in the edge cutting device and an average temperature T2 of the endless base profile during separation, there is a temperature difference T1−T2 of 2 K≤T1−T2≤15 K. Due to distance (D) within an optimum temperature range, further processing of the cut off edge areas is essentially neutral in terms of installation space.
