    摘要: An attaching device includes: a first attaching roller, a second attaching roller, a first distance measurement instrument, and a second distance measurement instrument. The first distance measurement instrument is to measure a distance between a first position of the first attaching roller and a second position of the second attaching roller. The second distance measurement instrument is to measure a distance between a third position of the first attaching roller and a fourth position of the second attaching roller. A straight line defined by the first position and the third position is parallel to an axial line of the first attaching roller, and a straight line defined by the second position and the fourth position is parallel to an axial line of the second attaching roller.
