Abstract

The invention concerns a method and installation during pulling of the drying wire of the paper machine, in which method the drying wire is pulled into a multicylinder dryer with several wire groups R1, R2 after each other of which there are suitably two rows of cylinders and in which the drying wire is guided in the form of a closed link from the drying cylinders to a roll, preferably a suction roll and then to a drying cylinder. In the method the drying wire H1 is conveyed with an auxiliary drive device in conjunction with group intermediate space R1, R2 in which the speed on the wires in the groups R1, R2 lying next to each other is the same or the speed difference is the desired difference at the transfer point of the web from group R1 to group R2. According to the method, the torque and/or speed is controlled by a roll which guides the wire in contact with the group intermediate space by means of an auxiliary drive device, preferably a motor M with controllable torque, in which by controlling the torque of the auxiliary drive to the desired magnitude the speed on wire H1 is made the same as for wire H2 in the following drying cylinder group. <IMAGE>
