Embodiment Construction

[0024] The folding machine shown in Fig. 1 comprises a first folding device 23 with two folding rollers 24,26 and a second folding roller 28,30 connected behind the first folding device 23 Two folding device 29. Arranged upstream of the first folding unit 23 is a first skewed roller table 16 which, in a known manner, has a positioning side rule 20 which extends in the transport direction TR1 of the sheets 36 . Ideally, the sheet 36 touches the positioning side rail 20 via the first inclined roller table 16 and is then guided in the transport direction TR1 between the folding rollers 24 , 26 and folded by them. After passing the folding rollers 24 , 26 , the folded sheet 39 is conveyed onto the second skewed roller table 18 , whose conveying direction TR2 runs perpendicular to the conveying direction TR1 of the first skewed roller table 16 . The sheet 39 will come into contact with the positioning side rails 22 via this skewed roller table and is then guided between the foldin...

Abstract

In the method for monitoring the position of a sheet ( 36, 38, 48 ) transported in a folding machine, during the transport of the sheet ( 36, 38, 48 ), at a detection location, the positions of a sheet edge ( 37, 39, 49 ) running substantially in the transport direction (TR) are determined by a detection device ( 32, 34, 46 ). Measured values corresponding to the positions detected are then passed on to a processor device by the detection device ( 32, 34, 46 ). The processor device calculates a measured curve (MK 1, MK 2, MK 3 ) on the basis of the detected measured values and the travel of the sheet ( 36, 38, 48 ) through the detection location and compares this with a previously determined reference curve (RK). The processor device outputs an error signal if the measured curve (MK 1, MK 2, MK 3 ) deviates from the reference curve (RK).

Description

technical field [0001] The invention relates to a method for detecting the position of sheets conveyed in a folder. Background technique [0002] In the folding unit of a folding machine, the sheets are folded in such a way that after the folding process all the edges of the sheets overlap in alignment. The prerequisites for this are that the sheets are cut at absolutely right angles, that the sheets are fed at right angles to the longitudinal axis of the folding rollers and that the folding rollers have the same tension across their working width. Folding in folding fences requires that the folding fence be positioned at no angle to the direction of sheet transport and that its clear width between the fence bars be optimally selected. Furthermore, the sheet stop in the folding fence must be adjusted at right angles to the direction of transport. [0003] In order to correct possible errors, adjustment devices are provided at the corresponding positions of the folding mach...
