ABSTRACT:
An arrangement for automatically feeding sheets of paper of varying rectangular formats into an automatic zigzag folding machine allows sheets to be processed whose lower edge of the printed side is on the opposite side. Processing can take place in the same machines together with regular sheets, and the results are the same. For this purpose the sheets are inverted about an axis at a right angle to the direction of advancement by use of the feeding channel, and the sequence of the folding machine is changed to work in reverse order.
