    摘要： An inclined position of a product, leaving a nip between two folding rollers of a longitudinal folding machine, is corrected. The product is pressed into the nip between the rollers by a folding blade that can be moved up and down relative to a folding table. The product thus leaves the nip between the rollers and is transported in a direction of transport. The time of passage of a leading or a trailing edge of a product is detected at two measurement points which are spaced apart from each other and which are arranged transversely to the direction of transport of the product to be folded. Based on the times of passage that are detected by the two measurement points, and on commutation and/or data processing techniques, a deviation between a time offset detected during the passage of the corresponding product edge at the two measurement points, and a nominal time offset, is determined and analyzed. In the event that the deviation exceeds at least a tolerance range, a measure is initiated, by the use of a control device, in order to act against the deviation. The measure that is to be taken is based on retaining the product to a greater or lesser extent when the product is passing the folding rollers and/or in the provision of more or less friction between the braking elements and the product.

    摘要： A longitudinal folding machine comprises a folding blade and a folding table. The folding blade is driven with a cyclical frequency, in a synchronized manner relative to one or more elements of a web-processing machine, which is located upstream of the longitudinal folding machine, or relative to a flow of incoming products. The entry of a leading edge of products is detected at a first measurement point on the delivery route of the folding table. A relative phase position between the movement of the folding blade and the phase position of the elements mounted upstream and/or the phase position of the flow of products is deliberately modified by the use of one of a control and a regulation device in order to adjust a contact point of the folding blade with the products to be folded. The relative phase position is modified such that, at least in one operating mode or phase of production, the leading edges of the products to be folded, and which were transported on the folding table, are maintained at a distance from the measurement point on the delivery route by varying the relative phase position so that due to the detection of the leading edges of one or of a certain number of successive products at this measurement point, the relative phase position varies either for the first contact of the product and the folding blades and/or for the contact point having a placement nearer to the entry side of the incoming products.
