Abstract: The invention provides a gatherer stitcher having at least one stitching station (1) for stitching sheets, the stitching station being arranged on a stitching carriage that can move in the longitudinal direction (X) of a gatherer chain during the stitching operation and at least one ejector unit being provided after the stitching station in the transport direction of the sheets in order to eject the sheets, to provide a gatherer stitcher exhibiting a higher operational reliability as compared with the prior art. According to the invention, this is achieved in that at least one acceleration and/or braking unit (4) for accelerating and/or braking the sheets in the longitudinal direction (X) toward the ejector unit is arranged between the stitching carriage and the ejector unit.

Abstract: A stapling device (1) with at least two stapling heads (4, 5) attached to a stapling head unit (2) for stapling sheet-like material, in particular paper, cardboard or the like, is provided, wherein the distance between at least two stapling heads (4, 5) can be adjusted relative to each other. In a stapling device (1) according to the invention, the retrofitting necessary for various products is to be simplified. This is achieved in the invention by moveably arranging the stapling heads (4, 5) relative to each other, and providing a drive unit (9, 10) for setting the stapling head distance.

Abstract: A gatherer stitcher is provided having a common drive unit driving at least two operating shafts, at least one and/or at least two different operating units, such as more particularly a gatherer chain and/or stitching station and/or a feeder and/or stitching carriage and/or ejector and/or 3-cutter, comprising two operating shafts, which permits an automated change in the phase angle between the two shafts. According to the invention, this is achieved in that an adjusting apparatus having at least one adjustment drive (4) that can be monitored is provided in order to set a phase angle at least between the two shafts.

Abstract: The invention proposes a staple-forming apparatus which is intended for stapling machines for forming staples and may be designed to be smaller than priorart apparatuses. This is achieved according to the invention in that a locking bar (9) for locking a pusher in the forming apparatus during the operation of forming the staple is fitted in a moveable manner in the pusher and a fixed stop (13) for the locking bar (9) is provided on the housing (2) of the staple-forming apparatus.

Abstract: So that a staple driver does not perform a movement relative to a staple holder until the staple holder comes down on the material to be stapled, provision is made according to the invention for the staple holder and the staple driver of a stapling head to be driven by a common drive device via a cam control mechanism. The cam control mechanism has a cam plate which is made to perform a stroke movement via a drive pin on which it is rotatably mounted. The staple holder and staple driver are driven by two connecting rods which relative to the rotation axis act eccentrically on two sides on the cam plate. A stationary guide rail, against which the cam plate is supported with a guide surface during a first phase of the working stroke, prevents a rotary movement of the cam plate during the first phase of the working stroke and thereby fixes the staple driver relative to the staple holder.
