6. method of adjustment of strip in-plane bending building mortion roll-adjusting gears according to claim 1 is characterized in that adjustment process is:
First work step: regulate the gap adjustment bolt (24) on the clearance adjuster (9), clearance adjuster (9) is separated with two awl roll shafts (4);
Second work step: the overhang of slide block shaft coupling in the adjusting slider shaft coupling, to regulate the overhang of two awl roll shafts;
The 3rd work step: the bolt on the adjustment angle of wedge adjuster (7), realize the adjusting of two awl roll shaft (4) angles;
The 4th work step:, make clearance adjuster (9) contact and change the width of the wedge shape roll gap of two awl roll shafts, 4 formation with two awl roll shafts (4) through regulating the bolt on the clearance adjuster (9).
