ABSTRACT:
The invention relates to a sheet stacker for sheets in particular of thin material, such as paper. In order to be able to change the stack without reducing the conveying speed of the sheets conveyed in an overlapping manner and without wasting sheets, free spacers 18 are provided on the underside of the table plate 7 of the transfer table 3 between the conveyor belts 8 for its guide and conveying rollers 10-14 and its bearing blocks 16, which free spacers receive the bars 19 of a bar screen. The bars 19 of the bar screen are arranged above the upper level of the stack 46 and may be inserted in the open gusset between the sheets 1 conveyed in an overlapping manner an the stack 46. Additional separators, which only facilitate an insertion of the bars 19, are no longer necessary.
