摘要： A data base used for determining the amount of decrease in the bobbin rotational speed that corresponds to an increase in the number of roving layers, along with silver weight, fiber kind, the number of revolutions of a flyer and the number of laps over presser, etc. as variables, is stored in a program memory. Based on roving conditions entered through an input unit and the data base stored in the program memory, a CPU calculates the amount of decrease of the bobbin rotational speed that corresponds to the increase in the number of sliver layers. With a control signal output from the CPU in response to the increase in the number of sliver layers, a wind-up motor is controlled to slow down so that the bobbin rotational speed is gradually reduced by a predetermined amount. The bobbin rotational speed is also controlled depending on the sliver position between a front roller and a flyer top.
