The patent US11993042B2 describes a tire building machine that features a stitching roller and a tire building drum. The stitching roller is designed with a rotatable roller body that includes a circumferential member, which has a stitching surface facing away from the roller axis and an internal surface facing towards it. The roller body is supported by a flexible support member that allows for elastic deformation, enabling the circumferential member to tilt from a neutral orientation to a tilted orientation. This support member is characterized by varying axial stiffness along its length, with reinforcements at specific radii to enhance its structural integrity. The design aims to optimize the stitching process by allowing the circumferential member to adapt during operation, improving the machine's efficiency.

Additionally, the patent outlines various configurations for the support member, including its width and reinforcement structures, which contribute to its flexibility and strength. The support member's design allows for a gradual decrease in width from the base end to the connection end, and it can feature a homogenous material composition. The circumferential member is also described as being rotation symmetrical, with a cylindrical stitching surface in its neutral orientation. The method of stitching a strip onto the tire building drum is also included, emphasizing the integration of the stitching roller in the overall tire manufacturing process. The patent highlights the innovative aspects of the stitching roller's design, which are intended to enhance the performance and adaptability of tire building machines.
