Control closely based on sets of winding data of a fiber bundle is performed even if at least one set of the winding data is skipped. A controller includes a data conversion unit, a reference data setting unit, a transfer unit, and a selector. The data conversion unit converts sets of first winding data generated based on winding conditions into sets of second winding data in which a processing order number is associated with information of a state of a winder. The reference data setting unit sets some of the second winding data as sets of reference data in advance. The transfer unit transfers a selected set of the second winding data to the winder, each time a unit time elapses. The selector is able to set an override value that is used for determining a skip number.
