Abstract:
A non-glued laminated ball includes an inner bladder, a yarn layer, a rubber layer and an outer cover layer. The yarn layer sticks to an outer surface of the inner bladder. The rubber layer is provided between the yarn layer and the outer cover layer. The outer cover layer includes a plurality of outer covers. Stalk lines are provided among the outer covers. Bottom layers of the outer covers are required to be loose. The outer covers bond to a rubber raw material of the rubber layer through a mold-closing pressurization bonding. Then, through vulcanizing, the rubber raw material permeates into the yarn layer and the loose bottom layers of the outer covers for integrating the inner bladder, the yarn layer, the rubber layer and the outer cover layer together. No glue, industrial gasoline or methylbenzene is provided between the outer cover layer and the rubber layer.
