Abstract (en)
[origin: US4775136A] To permit introduction of spreading fingers or insert sheet or sheet packages between essentially adjacent positioned sheet elements or halves (4a, 4b) of a folded sheet, the sheet is folded incompletely by extending a fold or spine or crease line or partly across the sheet while leaving a terminal portion in form of an open loop. The insert element, which may be spreading fingers (13, 23, 24), spreading disks (25, 26) or another sheet (31), is then engaged within the loop which, after insertion of the insert element, can be compressed, for example by cams (20) to form a crease also in the previous loop position. The transport of the incompletely folded sheet is carried out by transporting the sheet between, for example, transport belts, with the open loop projecting laterally from the transport belts so that they will not be squeezed or compressed.
