<p>Provided is a manufacturing method for a bundle product that includes an inspecting step of inspecting two or more threads continuously running in parallel in the longitudinal direction, a collecting step of collecting the threads, and a cutting step of cutting, after completion of the collecting, all the collected threads at a predetermined position, to obtain a bundle product having plural threads converged into a bundle. In the manufacturing method, an amount of collection in the collecting step is adjusted on the basis of inspection results obtained in the inspecting step so that at least one managed quantity for plural threads selected from a group including a total number, a total weight, a representative weight, a total outside diameter value, a representative outside diameter value, a total surface area, and a representative surface area of the plural threads constituting the bundle product exceeds a predetermined value.</p> |
