摘要： Disclosed is a winding method using an air expansion structure, which accurately controls the winding process by preset inflation parameter values and preset winding parameter values, so as to create space for a membrane to contract after winding, that is, to relieve the stress of the membrane, so as to avoid the situation of deviation or innermost side wrinkling during winding of the membrane, and the rewinding procedure is not needed, so that the complexity of the working procedure is reduced.
