Abstract: A support strip and a method of new tensioning. The support strip includes a support segment and a predetermined cutting segment. Each of two ends of the support segment is connected with the predetermined cutting segment in a length direction of the support strip. The support segment includes a support body and a covering portion. The support body extends in a length direction. The covering portion is located at a first side of the support body. A second side of the support body is opposite to the first side in a width direction perpendicular to the length direction. The predetermined cutting segment comprises an offset-compensating portion. A first side edge of the offset-compensating portion extends in the length direction. A second side edge of the offset-compensating portion is inclined from the second side to the first side.
