Abstract
In a winder provided with a control device capable of independently controlling rotational speeds of both motors for a friction roller having a winding package placed thereon and a traverse mechanism, a driving method for a winder comprising: obtaining a difference between an output of a first sensor for detecting a rotational speed of a package and an output of a second sensor for detecting a rotational speed of a friction roller, attenuating the difference to an adjustable value to prepare a correction value, subtracting the correction value from the output of the second sensor, and using the result obtained therefrom as a control input of the both motors to enable selection of a plurality of winding patterns.
