Method of and apparatus for manufacturing webs around cores using length and diameter data of cores

摘要

Core data required to manufacture rolls in a film processing and cutting machine are obtained, and core data of cores supplied by a core supply apparatus are also obtained. These core data are compared with each other, and cores having the conforming core data are selected and supplied to the film processing and cutting machine. When supplied with the cores, the film processing and cutting machine winds films cut to a given length and width around respective cores, and then supplies obtained products to a main feed unit according to the sequence of address information established on a film roll.
