The invention relates to a winding device for winding strips made of viscous material. The winding device comprises a winding roller which is driven by the drive motor through rotation, at least one carrying roller set on the upper part of the winding roller, and an intermediate roller. The strip to be wound moves to the winding roller through the carrying roller; an intermediate band is wound on the intermediate roller, and a piece of brake equipment is set on the intermediate band to affect the speed of the intermediate roller. According to the invention, an inspection device used for detecting the actual diameter (dW) of the winding roller (3) and the actual diameter (dZ) of the intermediate roller (4) is set, wherein a control device (12) is set to control the drive motor (9) for the purpose of setting the rotary speed based on the actual diameter (dW) of the winding roller (3) detected, and the control device (12) can control the brake equipment (11) to set the rotary speed of the intermediate roller (4) based on the actual diameter (dZ) of the intermediate roller (4).
