Detailed Description
The invention provides a method for confirming the effectiveness of identifying the bubble defects in a giant tire by using X-rays, which comprises the following steps:
s1: when a new product is manufactured in a trial mode, two sides of each belt ply are symmetrically attached with a plastic cloth liner 5 with the thickness of 4mm x 2.5mm x 1.0mm (note: length x width x thickness) respectively to serve as artificially manufactured bubbles, and the plastic cloth liners 5 with different belt plies positioned on the same side are staggered up and down; the specific operation is as follows:
a: after the first belt layer is attached, symmetrically attaching plastic laying cloths a1 and a2 on two sides of the end part of the 1# belt layer 1, and then marking a on an attaching drum on the corresponding side; then, the 2# belt ply 2 is laminated, after the lamination, the plastic laying cloths b1 and b2 are symmetrically laminated on two sides of the end part of the 2# belt ply 2, and the corresponding side of the laminating drum is marked with b; similarly, the 3# belt ply 3 is laminated, the c1 and the c2 are placed, the c point is marked until the n # belt ply 4 is laminated, and the n1 and the n2 are placed and the n point is marked; the marking points a, b and c are staggered and misaligned;
