Abstract
The invention relates to a device for stacking printed materials in sheet form, for example printed sheets, with the lateral edges of the sheets aligned. According to various aspects of the invention, methods and devices for stacking printed sheets on a stacking element are provided comprising a transport path to the stacking element comprising a first transport element and a second transport element, wherein the position of the second transport element is changeable along the transport path, at least the second transport element remaining stationary during the transport of sheets.
Claims20
A device for stacking printed sheets on a stacking element, comprising:
- a transport path to the stacking element comprising a first transport element and a second transport element, wherein the position of the second transport element is changeable along the transport path, at least the second transport element remaining stationary during transport of sheets.
A device for stacking printed sheets on a stacking element, comprising:
- a stop disposed at one end of the stacking element;
- a transport path to the stacking element comprising a first transport element and a second transport element, wherein the position of the second transport element is changeable along the transport path, at least the second transport element remaining stationary during transport of sheets, wherein the transport sends the sheets to the stop;
- rear joggers below the transport path moveable in a direction of sheet transport to jog a rear of the stack;
- and
- opposing jogging devices moveable in a direction transverse to the transport path, wherein the opposing jogging devices cooperate for the lateral alignment of sheets on the stacking element.
A method for stacking printed sheets on a stacking element, comprising:
- delivering the sheets to the stacking element via a transport path comprising a first transport element and a second transport element opposite the first transport element;
- and,
- changing a position of the second transport element along the transport path, at least the second transport element remaining stationary during transport of sheets.
The method of 13, comprising an aligning paddle disposed above the stacking support, and comprising maintaining control of each sheet with the transport path until sheet contact with the aligning paddle has already been made.
