SNUG FITTING APPARATUS FOR TIRE ASSEMBLY AND METHOD OF MANUFACTURING IT USING SNUG FITTING PROCESS

摘要

A snug fitting apparatus for improving the finished quality of a tire assemblywithout sacrificingproductivity, including a first pressing member adapted to be pressed againstthe ground contactsurface F of a tire assembly and a second pressing member adapted to bepressed against theground contact surface F to receive the radial reactional force of the groundcontact surface F.A measuring device is provided to read variations in the reactional force. Ifthe reactional forcevariation is determined to be above a threshold value, the entire process isrepeated until asuitable variation in reactional force is measured. As a result, a large,expensive uniformitychecking machine is made unnecessary, making it possible to assure quality forall the quantityof tire assemblies on the production line and to fully automate the process.
