Publication number: 20140073465Abstract: A seamless laminated basketball has a carcass and multiple outer covers attached to an outer surface of the carcass. Each outer cover has a thin portion formed around a peripheral edge of the outer cover and seamlessly connected to the thin portions of adjacent outer covers. As widths of the thin portions of the outer covers change, widths of recessed ball channels of the seamless laminated basketball change accordingly. Molds for manufacturing the carcass do not have to be remade or changed. Therefore, the seamless laminated basketball has simplified manufacturing processes and lowered manufacturing cost. Moreover, the outer covers are seamlessly connected to one another, which provides the laminated basketball an intact appearance. Furthermore, the connected outer covers prevent each other from peeling away from the carcass.Type: ApplicationFiled: November 13, 2012Publication date: March 13, 2014Inventor: I-Ting LEE
