Abstract (en)
[origin: EP2738123A2] The method involves successively accelerating the bobbin drive roller (4) to preset acceleration stages. The angular velocities of bobbin drive roller and cross-wound bobbin (3) are detected and compared with each other, so as to start next stage of acceleration. The time required for synchronization of circumferential speeds of cross-wound bobbin and bobbin drive roller is measured. The threshold value of acceleration stage is changed based on the preset deviation from nominal time period of the start of the acceleration stages.
