Abstract
The object of the present invention is to obtain a contact pressure control device capable of carrying out feedback control enduring a practical use by inventing a pressure detecting means and the employment structure of the same. The contact pressure control device of the take-up winder comprises a bobbin holder , a contact pressure roller contacted against the bobbin B set on the bobbin holder , a slide supporting mechanism (s) for supporting the contact pressure roller elevating or descending to the machine main body , and a contact pressure cylinder freely adjusting the contact pressure of the contact pressure roller and the bobbin holder . Moreover, a load cell is provided directly below one contact pressure cylinder located between a pair of slide supporting mechanisms (s), (s). Furthermore, a print circuit board for controlling is provided for controlling the contact pressure cylinder based on the detected value of the load cell so that the contact pressure is to be maintained at a designated value.
