Abstract
A lay-flat removal device for a plastic tube film web with a lay-flat and squeezing device having lay-flat plates and squeezing rolls that are rotatable in a reversing manner around an axis of a supplied film tube. The removal device includes a first reversing, non-rotational pneumatic reversal rod and a first reversing, rotating deflection roll mechanically connected to one another in a first fixed transmission ratio to form a first functional pair which is driven by a first motor, and a second reversing, non-rotational pneumatic reversal rod and a second reversing, rotating deflection roll mechanically connected to one another in a second fixed transmission ratio to form a second functional pair driven by a second motor. The motors are controlled in such a way that the different functional pairs cover angles of rotation that can be determined in a variable manner.
