PURPOSE:To make a degree of susceptibility of warp lower than rolling reduction, by making at least one of large diameter rolls movable in the direction falling at a right angle with a roll shaft, and making a roll pitch of the large diameter roll variable. CONSTITUTION:At least one of large diameter rolls 3a, 3b for straightening warp is made movable in the direction falling at a right angle with a roll shaft 5. That is, a gear 8 is fitted to a bearing 6 for supporting the shaft 5 of the large diameter roll 3a, so that it can vary a pitch P between the large diameter rolls 3a, 3b by rolling to the left and right on a rack 7. |
