A sheet processing machine comprises a receiving area () for collecting a sheet pile and a device () for determining the height of the sheet pile. The device () comprises a manually displaceable first sensor element arranged at a first side () of the receiving area (), and an automatically displaceable second sensor element () arranged at an opposite side () of the receiving area () such that the first and second sensor elements () are arranged opposite each other along a width direction of the receiving area (). The first sensor element and the second sensor element () are displaceable along a length direction of the sheet receiving area (), wherein the first sensor element is one of a light emitting source and a light receiving sensor () and the second sensor element () is the other one of a light emitting source and a light receiving sensor (). The light emitting source and the light receiving sensor () form a light barrier () along the width direction when facing each other.

An arrangement () for handling flat elements (), in particular paper elements (). A guiding structure () is provided, along which a flat element () is guidable and transportable along a transport direction (T). A hold-down element () is coupled to the guiding structure () for holding down the flat element () to the guiding structure (). The hold-down element () has a support section () on which the flat element () is supportable. The hold-down element () extends along an extending direction () having a component perpendicular to the transport direction (T), wherein suction holes () are arranged along the extending direction (). A suction unit () includes a suction opening () coupled to the suction holes () of the hold-down element (), an air inlet () and an air outlet (), wherein the suction unit () directs air from the air inlet () to the air outlet () for generating an air flow (). The suction opening () is formed and arranged such that the air flow () passes the suction opening () so that air flow () entrains air through the suction opening ().

A slowing device includes a flexible slowing member that extends transversely to the trajectory of sheets being fed. The member is movable between at least two limit positions, one in which its trajectory encounters that of the sheets, the other in which the slowing member is moved aside from the trajectory of the sheets. A drive device moves the slowing member between its limit positions. The drive device for the slowing member includes a pneumatic actuator which acts on a linear cam that pivots about a transverse shaft. A roller rolls along the surface of the linear cam. The roller and the slowing member are supported by a support that pivots about a transverse shaft.
