Abstract

A device for applying coiling-tension to a slit band sheet includes an upper structure that is disposed on the upper side of a band sheet which has been passed through a slitter line and slitted; and a lower structure that is disposed on the lower side of the band sheet and faces the upper structure vertically. In addition, an upper belt is stretched on an outer peripheral surface of the upper structure. A lower belt is stretched on an outer peripheral surface of the lower structure. The upper structure has a first reversing portion, an upper pressing portion, and a second reversing portion. The first reversing portion and the upper pressing portion are integrated with each other. A tension adjusting mechanism is installed on side surfaces of the first reversing portion and the upper pressing portion and a side surface of the second reversing portion.
