Abstract
A cross stacker comprising an integrated looping arrangement serves for alternate deposit of in particular folded printed products on a stack and for the subsequent looping of the stack with the help of a looping strip. Suitably, such a cross stacker is provided with a machine table, a working table, a rotary table integrated in the working table and having a catcher for the printed products to be stacked, and a looping arrangement, which is integrated in the cross stacker and which comprises an insertion, tensioning and welding device as well as a strip guide for the guidance of the inserted looping strip as a loose loop around the finished stack.

A combined cross stacker and looping arrangement for an alternate deposit of printed products (13) on a stack (26) and for a subsequent looping of the stack (26) by means of a looping strip (23), comprising:
- a machine table (3),
- a working table (4, 4') disposed on the machine table (3),
- a rotary table (6), which is integrated in the working table (4, 4') and has a catcher (12) for the printed products (13) to be stacked,
- a looping arrangement integrated in the cross stacker and comprising
- an insertion device (21) for an insertion of the looping strip (23),
- a strip guide (24) for a guidance of the inserted looping strip (23) as a loose loop (25) around the finished stack (26), and
- a tensioning and welding device (21), disposed under the working table (4, 4'), for tightening the loose loop (25) around the stack (26) and connecting the lapping end of the looping strip.
A cross stacker and a looping arrangement for an alternate deposit of printed products (13) on a stack (26) and a for subsequent looping of the stack (26) by means of a looping strip (23), comprising:
- a machine table (3), a working table (4, 4') disposed on the machine table (3),
- a rotary table (6), which is integrated in the working table (4, 4') and has a catcher (12) for the printed products (13) to be stacked,
- a looping arrangement integrated in the cross stacker and comprising
- an insertion device (21) for an insertion of the looping strip (23),
- a strip guide (24) for a guidance of the inserted looping strip (23) as a loose loop (25) around the finished stack (26), and
- a tensioning and welding device (21), disposed under the working table (4, 4,'), for tightening the loose loop (25) around the stack (26) and connecting the lapping end of the looping strip,
- wherein the strip guide (24) comprises guide-passage sections (27), in which the looping strip (23) is mechanically guided, and a free distance in air (29), over which a leading end of the looping strip (23) is inserted horizontally traversing a lifting range of the working table (4, 4') with the catcher (12).

- a vertically oriented guide-passage section (27.1) on one side of the working table (4, 4') with the catcher (12),
- a horizontally oriented guide-passage section (27.2, 27.3) under the working table (4, 4'), and
- in addition to the horizontal free distance in air (29), another free distance in air (32) in the vertical direction on such side of the strip guide (24) as is opposite to the vertically oriented guide-passage section (27.1).
A cross stacker and a looping arrangement for an alternate deposit of printed products (13) on a stack (26) and a for subsequent looping of the stack (26) by means of a looping strip (23), comprising:
- a machine table (3),
- a working table (4, 4') disposed on the machine table (3),
- a rotary table (6), which is integrated in the working table (4, 4') and has a catcher (12) for the printed products (13) to be stacked,
- a looping arrangement integrated in the cross stacker and comprising
- an insertion device (21) for an insertion of the looping strip (23),
- a strip guide (24) for a guidance of the inserted looping strip (23) as a loose loop (25) around the finished stack (26), and
- a tensioning and welding device (21), disposed under the working table (4, 4,'), for tightening the loose loop (25) around the stack (26) and connecting the lapping end of the looping strip,
- wherein the catcher (12) comprises two rigid side pieces (14, 15), which oppose each other and which are completed by pivoted flaps (16, 17) articulated to them.
