Abstract
The disclosure is directed to a machine for applying an endless precured tire tread to a prepared tire casing. A tread assembly is mounted for movement along guide rods supported by a base. The tread assembly includes a rotatably mounted head assembly having finger assemblies which mount an endless precured tread. The finger assemblies are movable radially inwardly and outwardly. A tire mounting assembly is positioned on said base in opposed and aligned relationship to the head assembly and mounts a prepared tire casing. Rollers are provided for stitching the endless tread to the prepared casing.
Claims10
A tread applying machine comprising, in combination, a base, a tread assembly mounted for movement on said base, said tread assembly including a head assembly mounted to rotate about an axis, said head assembly including means for retaining an endless tread, tire casing means for rotably mounting a prepared tire casing in opposed and axially aligned relationship with said head assembly for rotation about said axis, and roller means for joining a retained precured endless tread to a mounted prepared tire casing while such tread and casing are simultaneously rotated about said axis, whereby the precured endless tread can be initially tacked to such casing with pressure exerted by said roller means while such endless tread is retained on said head assembly.
A tread applying machine comprising, in combination, a base, a tread assembly mounted on said base, cylinder means for moving said tread assembly along said base, said tread assembly including a bearing assembly, a head assembly mounted by said bearing assembly for rotation about an axis, said head assembly including a plate member having a plurality of radially extending threaded shafts mounted thereon, said tread assembly including a shaft mounted for rotation, a main gear mounted on said shaft, a plurality of follower gears mounted on said threaded shafts and meshing with said main gear, a finger assembly threadably mounted on each of said threaded shafts, whereby rotation of said horizontal shaft with respect to said plate member moves said finger assemblies radially inwardly or outwardly, said finger assemblies receiving and expanding a precured endless tread, tire mounting means mounted on said base in axially aligned relationship with said head assembly, said tire mounting means including rotatable chucking means for mounting a prepared tire casing for rotation about said axis, and roller means for joining an expanded precured endless tread on said tread assembly to a prepared tire casing on said tire mounting means while such tread and casing are simultaneously rotated.
