AI Technical Summary

Technical Problem

The existing transfer wheel does not hold the rear end accurately enough when transferring the bead wrap and rubber strip to the tire forming drum, resulting in insufficient splicing quality and potentially leading to inferior tires.

Method used

A transfer wheel is designed, including an annular body and two support surfaces, the second support surface being recessed relative to the first support surface. It is equipped with a rear-end retaining member and a body retaining member, which hold the tire component by magnetic or suction methods, control its stretching and position, and ensure accurate transfer.

Benefits of technology

It improves the accuracy and splicing quality of tire components on the tire forming drum, reduces deformation and sagging, and ensures the precision of tire forming.
