ABSTRACT:
The folded products are not completely creased across their width in a folding apparatus but, rather, leaving an open loop or bulge or end portion (101). A separating cylinder (100) includes gripper or holding elements (38-41) located spirally about the circumference of the cylinder, in groups, and axially shiftable, for insertion of the grippers, sequentially, into said open loop. After the first gripper moves to an insertion position, it opens the sides of the folded products for insertion of subsequent grippers or holding elements along the length of the folded sheet. A fixed guide element strips the folded sheets off the cylinder, at which time the grippers, sequentially, withdraw from the insertion position, the trailing gripper elements holding that one (8) of the folded sheet portion which is closest to the cylinder against the circumference thereof, whereas the other portion (7) can fly out under centrifugal force, to thereby provide the folded product in separated form to a subsequent transport or storage pocket system (75), for example in form of a zig-zag storage structure.
