US 2026/0257441 A1 · PNEUMATIC TIRE, TIRE PROCESSING MACHINE, WHEEL, METHOD, CONTROL DEVICE, AND COMPUTER PROGRAM PRODUCT

Abstract

Disclosed is a pneumatic tire having a bead having a bead base facing the rotational axis of the pneumatic tire; wherein the bead base has a protrusion extending toward the rotational axis and in a circumferential direction of the bead base; and wherein the protrusion has a geometry varying in the circumferential direction. Further disclosed is a pneumatic tire having a bead having a bead base facing a rotational axis of the pneumatic tire; wherein the bead base comprises a surface structure generated by removal of tire material along processing tracks in a processing region of the bead base; and wherein the surface structure is undulated. Further disclosed is a method and a tire processing machine for manufacturing the pneumatic tire. Further disclosed is a method for operating a tire processing machine, a wheel comprising the pneumatic tire, and a control device for controlling a method and a computer program product for controlling the method.

Dependent claims

1-68. (canceled)

A pneumatic tire comprising:

a bead having a bead base facing the rotational axis of the pneumatic tire;
wherein the bead base comprises a protrusion extending toward the rotational axis and in a circumferential direction of the bead base;
and
wherein the protrusion has a geometry varying in the circumferential direction.

1 more element

A method for processing a pneumatic tire, wherein the pneumatic tire comprises a bead base, wherein the pneumatic tire defines an axial direction parallel to the rotational axis of the pneumatic tire and wherein the pneumatic tire defines a circumferential direction around the rotational axis, the method comprising:

removing of tire material in a processing region of the bead base and thereby generating a protrusion extending toward the rotational axis and in the circumferential direction and wherein the protrusion has a geometry varying in the circumferential direction.

A tire processing machine for processing a pneumatic tire, wherein the pneumatic tire to be processed comprises a first bead and a second bead, wherein the pneumatic tire defines an axial direction parallel to a rotational axis of the pneumatic tire and wherein the pneumatic tire defines a circumferential direction around the rotational axis, the tire processing machine comprising:

at least one first holding finger which is engageable with the first bead;
at least one second holding finger which is engageable with the second bead;
wherein the at least one first holding finger is operable to rotate the pneumatic tire with respect to the at least one second holding finger.
