  • Method and device for folding round pockets
    Patent number: 6401642
    Abstract: A process for folding or folding over pockets with round edge sections is provided along with a device for carrying out the process. Round folding slides (9; 53), provided with concave folding edges (49; 54), are either moved or designed such that their ends (50, 51; 55), either one after another or simultaneously, lead in relation to the middle area of the concave folding edges (49; 54). An especially intense folding effect is thus exerted on the transition areas between the round and straight pocket edge sections and a pocked folded edge that is uniform on all sides is thus obtained.
