Abstract: A detection system for detecting double sheets being supplied to a lateral positioning device (100) for a sheet element (20, 20?) in a sheet element processing machine. The machine has a drive system including a cam disk (174) and a cam follower lever (172). The detection system includes a detector lever (130) mounted so as to be displaceable between a sheet receiving position and a detection position. The detector lever (130) has a sheet sensing end (132) for engagement with an upper face of the sheet element (20, 20?) when being in the detection position, and a position detector end (133) for cooperating, when being in the detection position, with a position detector (140) adapted for generating a signal dependent on the thickness of the sheet element (20, 20?), and further includes a raising lever (170) for raising the sheet sensing end (132) of the detector lever (130). The raising lever (170) is mounted on the cam follower lever (172) of the sheet element processing machine.

Abstract: A lateral positioning device (100) for a sheet element (20, 20?) in a sheet element processing machine; a detector lever (130) articulated relative to a horizontal axis, which performs a descending movement from a high position to a low position; a first end (132) of the detector lever (130) contacts, in a low position of the lever, with an upper face of the sheet element. A second end (133) of the detector lever (130) is fitted with a target (135) that cooperates with a position detector (140) to generate a signal dependent on the thickness of the sheet element (20, 20?) and the number of sheet elements (20, 20?) present at the level of the first end (132) of the detector lever (130).
