  • Butting device for joining running steel sheets
    Patent number: 5172846
    Abstract: The device of this invention is to prevent the buckling of steel sheets and positional discrepancy between steel sheets by grasping and butting the front and rear ends of sheets by means of clamping means on a joining device carrier. For this purpose, a pair of joining device carrier 3 are moved on rails 8 mounted at both sides of rolls 9 for conveying steel. The rear end of the preceding steel sheet 1 and the front end of the following steel sheet 2 are grasped by the clamping means 4 and 5 on the joining device carrier, respectively. The clamping means 5 is moved close to the clamping means 4 by using a movable frame so that the steel sheets 1, 2 are butted together.
