A lay-flat and removal device for a plastic tube film web produced by means of a stationary film blowing head whose lay-flat plates and squeezing rolls may be rotated in a reversing manner around the axis of the supplied film tube, having a subsequent fixed winding device or device for further processing as well as at least two reversing pneumatic reversal rods and at least two reversing deflection rolls, with one reversing, non-rotational pneumatic reversal rod and one adjacent reversing, rotating deflection roll together forming one functional pair, and with a separate motor being assigned to each functional pair. A process is also described in which the separate motors of the different functional pairs are controlled in such a way that the different functional pairs cover angles of rotation that can be determined in a variable manner.
