Abstract

PURPOSE: To obtain the objective breadth of sheet on the run-out side of th horizontal roll, by detecting the breadths of sheet on the feed-in side and run-out side of the vertical roll, and by adjusting the roll gap of the vertical roll depending on the relational expression established between said detected breadths and the thicknesses of sheet on the feed-in side and run-out side of the horizontal roll.
CONSTITUTION: The thickness H of blank material 10 fed into the horizontal roll 16 is detected by the screw position detector 42 and is in-putted to the operator 50 for operating the breadth of the sheet on the run-out side of the horizontal roll 16. The breadth W of blank material 10 running out of the horizontal roll 16 is measured by the measuring device 32 for the feed-in side breadth on the feed-in side of the vertical roll 12; the breadth WE on the run-out side of the vertical roll 12 is operated by the operator 40 on the run-out side of the vertical roll 12 depending on the output signals sent from the distance meters 38a, 38b; these values W and WE are both inputted to said operator 50. When the blank material 10 arrives at the horizontal roll 14, the screw position detector 44 detects the sheet thickness (h) and inputs it to the operator 50 which thereon operates the forecast for the breadth of sheet on the run-out side of the horizontal roll 14 depending on the inputted data H, W, WE, and (h). This value WH is compared with the objective breadth of sheet; correspondingly to thus obtained breadth deviation, the roll gap of the vertical roll 12 is adjusted by the roll gap controller 52 of the vertical roll 12.
