This also causes a temporary Swiveling the gripper fingers 3 in an open position of the same, so that a in each case in the effective range of a sheet brake 17 sheet 4 to this transferred, decelerated to a depositing speed by means of this and finally released, whereupon he lowered himself while lowering himself Front edge stops 18 moved and aligned with this and at these opposite trailing edge stops 19 together with previous and / or subsequent sheet 4 a stack 20 on a Stacking pad 21 forms, which can be lowered to the extent by means of a lifting mechanism is how the height of the stack 20 increases. 5 are only of the hoist a platform 22 and this carrying lifting chains 23 indicated by dash-dotted lines reproduced.
- the gripper bridges 1 are only symbolized in FIG. 5 in the form of grippers 9 and this associated gripper pads 2 each in a schematic representation reproduced.
- a respective gripper bridge 1 comprises further a front spoiler 25, by means of which between the gripper bridge 1 and the arch guide surface 6 existing space 26 can be shielded.
- a front spoiler 25 is in the same sense as the gripper fingers 3 and in one with the Gripper cycle correlated cycle swiveling.
- Front spoiler 25 on holders which are mounted on the gripper shaft 8.1 and opposite whose geometric axis 8 by a certain angle between the Interspace 26 shielding the first pivot position and one of the Bogenleit Structure 6 moved away second pivot position
- a Spring arrangement by means of which the front spoiler 25 in the same pivoting direction is biased as the grippers 9 on the part of those acting on them Are spring arrangement
- a roller lever by means of which the front spoiler 25th is pivotable against the action of the spring arrangement that biases it
- a spoiler control curve cooperating with said roller lever which is arranged and designed such that the front spoiler 25 has its recognizable second pivot position at least essentially takes when the gripper fingers 3 the gripper 9 of the cylinder 12 guiding the arc approaching gripper bridge 1 their lifted from the gripper pads 2 Take pivot position, and its first pivot position shown in Fig.
- the spoiler control curve is the Drive sprocket assembly 15 assigned and controls here in particular Avoiding a collision of the front spoiler 25 with the cylinder guiding the bow 12 intended pivoting of the front spoiler 25 in its second pivot position.

- the spoiler control curve assigned to the drive sprocket arrangement 15 is also arranged and designed so that the time interval in which the front spoiler 25 of the respective cylinder 12 passing the gripper bridge 1 is in its second swivel position, that is to say in the swivel position in which the front spoiler 25 would shield the intermediate space 26 between the latter and the gripper bridge 1 when passing the sheet guide surface 6 includes the time interval within which the grippers 9 of the gripper bridge 1 passing the respective cylinders 12 that are in the arc are opened.
- the angle by which the front spoiler 25 between its two pivot positions is pivotable, is chosen so that the front spoiler 25 in the second Pivotal position passes the cylinder 12 leading the arc without collision.
- the front spoiler 25 a respective gripper bridge 1 together with the gripper fingers 3 of the gripper 9 this gripper bridge 1 is pivotable.
- the Front spoiler 25 for example, fixed with a certain number of Gripper base body 7 of the gripper bridge 1 connected, so that this already results a clockwise correlation with the gripper cycle of the front spoiler 25 in same sense as the pivoting of the gripper fingers 3 results without a additional swivel mechanism for the front spoiler 25 is required.
- the spoiler clock i. H. the rhythm in which the Front spoiler 25 is pivoted operationally with the gripper cycle such that the Spoiler cycle and gripper cycle match.
- the front spoiler 25 will unnecessarily temporarily also in the area of the deflection sprocket arrangement 16 pivoted into its second pivot position; however, this can be done with regard to particularly simple means of realizing the intended purpose Swiveling the front spoiler 25 are accepted.
- the front spoiler 25 is designed and arranged such that the gripper 9 of the operationally rotating gripper bridge 1 in the slipstream of Front spoiler 25 are located.
- the front spoiler 25 has a cross section that is compared to the grippers 9 of the gripper bridge 1 downstream with respect to the Direction of conveyance extends.
- the gripper bridge 1 passes the sheet guide surface 6, the front spoiler 25 is in its first swivel position. That downstream located end of the cross section of the front spoiler 25 is at least in the immediate vicinity of the sheet guide surface 6 and can in the case of a rubber-elastic lip also slide on the sheet guide surface 6 at this end.
- the gripper bridge 1 is a measure for fulfilling these requirements, as in FIG. 2 recognizable, in addition to a first wall 27 carrying the gripper supports 2 with the front spoiler 25 downstream with respect to the conveying direction provided second wall 28. It is preferably provided that this second wall 28 together with the front spoiler 25 Flow channel 29 for the gripper bridge 1 tends to be opposite to the conveying direction air flowing through it.
