Abstract
A sheet inverting device and a method of inverting a folded sheet include an inverting element that inverts the sheet around an axis of rotation towards a receiving member for receiving the sheet, and at least one moveable stop member that limits, in a first position of the stop member above the receiving member, an unfolding movement of the sheet in a direction towards a far side of the receiving member. The stop member is adapted to be retracted from the first position into a second position of the stop member.

A sheet inverting device for inverting a folded sheet, comprising:
- a receiving member for receiving the folded sheet;
- an inverting element for inverting the folded sheet around an axis of rotation towards the receiving member;
- and
- at least one moveable stop member for limiting, in a first position of the at least one moveable stop member above the receiving member, an unfolding movement of the folded sheet in a direction towards a far side of the receiving member, wherein the at least one movable stop member is adapted to be retracted from the first position into a second position of the stop member.
A method of inverting a folded sheet comprising a large panel and a small panel that is folded, at a first edge side of the folded sheet, towards the large panel on a first side of the folded sheet, said method comprising the steps of:
- bending and rotating at least a second edge side leading part of the folded sheet around an axis of rotation;
- receiving the second edge of the folded sheet at a first end of a receiving member,
- limiting, by at least one movable stop member in a first position above the receiving member, an unfolding movement of the small panel of the folded sheet at the first side of the presently bent folded sheet in a direction towards a far side of the receiving member;
- retracting the at least one movable stop member from said first position and letting the first edge side of the sheet roll out towards the far side of the receiving member, and
- receiving the folded sheet with a second sheet side up on the receiving member.
