Abstract: A buckle plate device for a folding machine comprises a buckle plate (10) and a sheet stopping means for stopping a sheet (24) running into the buckle plate (10) in the intake direction, wherein the sheet stopping means is formed by a clamping means (26) which clamps the incoming sheet (24) in order to stop it and preferably automatically releases the clamping at the onset of tractive forces of the subsequent rollers. Hereby a buckle plate device is provided which requires little space and makes it possible to fold sheets with comparably low noise development without a mechanical stop in a sheet-edge controlled manner or in a print-image controlled manner at a high sheet transport speed.

Abstract: An apparatus for inserting packaged material into packaging means is described. In the region of an insertion device and a preinsertion device, a packaged-material conveyor device and a packaging-means conveyor device are provided. The insertion device has at least one insertion tappet, and the preinsertion device has a covering tongue corresponding to the insertion tappet. The insertion tappets and covering tongue can be guided essentially transversely to a direction of motion of the conveyor devices, which motions can each be generated by means of a respective servomotor drive mechanism, coupled to the insertion tappet and to the covering tongue. The insertion device and the preinsertion device are adjustable in oscillating fashion parallel to the direction of motion of the conveyor devices via a further servomotor drive mechanism coupled to them, and the drive mechanisms are triggerable separately via a drive control mechanism.

Abstract: A folding unit has at least one pair of folding rollers including an adjustable folding roller and a stationary folding roller or two adjustable folding rollers. At least two pressure measuring devices are associated to one adjustable folding roller, the pressure measuring devices being arranged at a distance from one another and measuring pressure values when a sheet passes therethrough. The pressure values correspond to pressures which are exerted on said sheet by the adjustable folding roller at two measurement points which are spaced apart transversely with respect to a sheet running direction. The pressure measuring devices forward measured pressure values to a processing device. Each adjustable folding roller is connected kinematically to a corresponding drive at two connection points which are spaced apart transversely with respect to the sheet running direction.

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 (MK1, MK2, MK3) 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 (MK1, MK2, MK3) deviates from the reference curve (RK).
