Abstract
PURPOSE: To stop the steel strip with good accuracy by moving the steel strip to the specified position by the looper roll which is driven by a driving machine.
CONSTITUTION: A looper roll 8 which operates a driving machine 9 when a steel strip 2 is welded in the position of a weld line 16 by a welding machine 1 is moved upward to move the steel strip 2 of the side more leftward than the roll 8 to the threading direction. Hence, the weld line 16 is moved to the flash trimmer 3 direction. The movement amount of this steep strip 2 is detected as the number of revolutions of a measuring roll 10 by a pulse generator 12 and is further counted 13. A servo mechanism 14 emits a driving command to the driving machine 9 to move the roll 8 upward. Also, it beforehand stores the distance between the weld line 16 and trimmer 3 and when the value of the counter 13 reaches said distance value, it stops the roll 8. As a result of this, the steel strip 2 is moved to the specified position by the roll 8 driven 9 and therefore the inertia of the roll 8 is small and the roll stops quickly, hence the accuracy of stopping may be improved considerably and the installation area of the device reduced.
