Abstract

In a device for winding a strip-shaped rubber member, a measured width and a measured thickness of a strip-shaped rubber member immediately before winding are measured by a measuring section at measurement point P. On the other hand, from a target width and a target thickness of the strip-shaped rubber member that are derived from a target sectional shape of a tread, an estimated width and an estimated thickness of the strip-shaped rubber member at the measurement point P are determined while taking deformation of the strip-shaped rubber member into consideration. Differences between the measured width and the estimated width, and between the measured thickness and the estimated thickness at each corresponding length direction position are determined.
