摘要

A method for running up of a web-fed rotary printing press with a printing material web (01) threading draw-in mechanism (02) and with a the printing material web (01) pulling traction roller (03), wherein a controllable and adjustable motor (04), the traction roller (03), wherein a said motor (04) of the traction roller (03) controlling control unit (06) or a the motor (04) of the traction roller (03) regulating control unit (06) is provided, wherein a control unit (07) the draw-in mechanism (02) controls or a control unit (07) the draw-in mechanism (02), wherein the said motor (04) of the traction roller (03) controlling control unit (06) or the motor (04) of the traction roller (03) regulating control unit (06) a measured value (ma) with respect to one of this motor (04), exerted on the printing material web (01) as a pulling force acting on the drive torque is detected and these measured value (ma) of the draw-in mechanism (02) control unit controlling (07) or of the draw-in mechanism (02) regulating control unit (07) available, characterized in that the draw-in mechanism (02) and / or the traction roller (03) prior to reaching a minimum value, for which the motor (04) of the traction roller (03), which is exerted on the printing material web (01) as a pulling force acting on the drive torque of the printing material web (01) with a comparison with the otherwise permissible speed, a reduced speed and in that after reaching the minimum value, for which the motor (04) of the traction roller (03), which is exerted on the printing material web (01) as a pulling force acting on the drive torque of the printing material web (01) from the draw-in mechanism (02) with a maximum permissible speed is drawn in, for which purpose a conveying means of the pulling mechanism (02) and, if appropriate, the traction roller (03) for conveying the printing material web (01) with respect to their respective rotation of their respective controllable or regulable drive unit to a maximum permissible value (sw) are accelerated.
