PROBLEM TO BE SOLVED: To provide a two-drum winder in which roundness of a wound article can be inspected at a winding stage of a band-like sheet.SOLUTION: There is provided a two-drum winder in which a winding shaft is disposed above two winder drums arranged in parallel, and which winds a band-like sheet around the winding shaft while rotating the two winder drums. The two-drum winder includes: shaft center position detection means for detecting a shaft center position of the winding shaft; rotational speed detection means for detecting rotational speed of the winding shaft; and first abnormality detection means that, at a final stage of the winding around the winding shaft, detects a plurality of shaft center positions of the winding shaft when the rotational speed of the winding shaft is reduced to a speed equal to or below a set speed, and that outputs an abnormality signal when deviations of the plurality of detected shaft center positions are greater than an allowed value of shaft center deviation. |
