Abstract
PURPOSE: To prevent the breakage of machine, the beat flaw of the strip, etc., by changing the position set signal of the wrapper roll system of the latter stage according to the signal produced from the wrapper roll system of the former stage.
CONSTITUTION: Before the strip 1 enters into the coiler, the initial gap of each wrapper roll is set nearly to the thickness Δh. When the tip of strip 1 passes No.3 wrapper roll 3 before entering into the second turn, a change in the hydraulic pressure of the hydraulic cylinder 12 is caused by the contact or collision of the strip 1 with the wrapper roll 3; this change in the hydraulic pressure is detected by the pressure detecting sensor 16, and the signal 28 is produced; according to this signal 28, the position set signal of No.1 wrapper roll 3 is changed by about Δh. That is, when the wrapping part 33 of the second turn passes under No.1 wrapper roll 3, No.1 wrapper roll 3 is being already pulled up by about Δh through adjusting the amount of liquid held in the hydraulic cylinder 12; as a result, the violet collision like as in the conventional method can be prevented.
