Folding apparatus for producing double laterally folded articles with a stitching device

摘要

To permit selectively stapling paper products which are to be folded in advance of formation of a first or a second cross fold, a stapling cylinder (18) can be selectively placed in engagement with a first folding blade cylinder (5) carrying transport needles (6) or a second folding blade cylinder (10) having folding blades and grippers (11) thereon. If the stapling cylinder (18) is engaged with the first needle and folding blade cylinder (5), staples can be placed into the products prior to formation of the first cross fold at the position of the fold line. Upon engagement of the stapling cylinder (18) on the gripper and folding blade cylinder (10), the once folded products are stapled at the fold line of a second fold, which is then carried out after stapling. The respective first and second folding blade cylinders include staple counter plates (13) to close the staples supplied by the staple applying stapling cylinder (18).
