Abstract: The uneven wear produced in a tread side rib in a heavy duty pneumatic radial tire (11) is prevented or reduced by arranging a peripheral fine groove (18) in a particular region of the side face (12b) of the tread portion (12) in a particular form. The fine groove has an opening (18a) of width corresponding to 5-75% of the width of a main groove (16) of the tread, and extends inward from a position (A) to a position defined by certain axial and radial distances (B,C).

Abstract: A method of measuring a gauge of used rubber portion of a buffed tire with an enhanced efficiency and high accuracy is disclosed, and in this method, workability of a buffing process can be improved. A buffing method is also disclosed which enhances a production efficiency of recaps, maintaining high levels of workability of the buffing process and quality of the recaps. An eddy-current sensor is used to measure a gauge g of used rubber portion or a thickness from an outer circumferential surface to a belt layer in a buffed tire to recap the tire, and voltages detected by the eddy-current sensor is converted in accordance with a conversion method designated to each of types of belt configuration to compute a real distance of the gauge of the used rubber portion. Also, after a buffed tire is rebuffed along its preliminarily buffed outer circumferential extension, the eddy-current sensor is used to measure a gauge g of used rubber portion or a thickness from an outer circumferential surface to a belt layer of preliminarily buffed tire T2, and then, an outer circumferential belt length Lb is computed from an outer circumferential length Lo of the preliminarily buffed tire and the gauge g previously measured. The outer circumferential belt length Lb is classified depending upon a tolerance for acceptable performance, a single outer circumferential length Lc of the buffed tire is specified to each of classified types of the outer circumferential belt length Lb, and the buffed tire is shaved along its outer circumference to have the outer circumferential length Lc as previously determined, so as to finish and shape the used tire into a base tire T3.

Abstract: The uneven wear produced in a tread side rib in a heavy duty pneumatic radial tire (11) is prevented or reduced by arranging a peripheral fine groove (18) in a particular region of the side face (12b) of the tread portion (12) in a particular form. The fine groove has an opening (18a) of width corresponding to 5-75% of the width of a main groove (16) of the tread, and extends inward from a position (A) to a position defined by certain axial and radial distances (B,C).

Abstract: Un procedimiento de pulimento, que comprende las etapas de: pulir un neumático pulimentado de forma preliminar a lo largo de su extensión circunferencial exterior, utilizando un sensor de corriente parásita (6) para determinar un espesor (g) de la porción de goma usada, que es el grosor desde una superficie circunferencial exterior hasta una capa de cintura (B) del neumático repulido para un subsecuente proceso de recauchutado; computar una longitud circunferencial exterior (Lb) de la cintura (B) a partir de una longitud circunferencial exterior (Lo) del neumático pulido de forma preliminar y el espesor de la porción de goma usada del neumático repulido determinado en la etapa anterior; clasificar la longitud circunferencial exterior (Lb) de la cintura (B) dentro de un tipo que varía dependiendo de una tolerancia para un rendimiento aceptable; especificar una longitud circunferencial exterior estandarizada (Lc) del neumático pulido para cada tipo de longitud circunferencial exterior de la cintura; y raspar la circunferencia exterior del neumático repulido hasta que su longitud circunferencial exterior alcance la longitud estándar especificada en la etapa previa para el acabado y conformación del neumático en un neumático de base.

Abstract: A re-treading method and an apparatus therefor, which are capable of winding a tread material on a base tire automatically and efficiently to realize an adequate joint condition of the leading and trailing edges of the tread material, are configured to take a photograph of a zone of the tread material including its cut position to compare the picture with a stored tread pattern image to detect a deviation amount between them, then moves the tread material or the cut position relative to each other by the deviation amount, next cut the tread material at the cut position after the relative movement, wind the tread material on a base tire, and unite the leading and trailing edges of the tread material. Alternatively, the re-treading method and the apparatus can detect a deviation amount of the position distant by a required tread length from the leading edge of the tread material from a predetermined pattern position near that position planned to be cut, cut the tread material at the at the predetermined position, wind the cut-out tread material on the outer circumference of the base tire while adjusting the length of the tread material by applying thereto a substantially uniform tensile or compressive force, and unite the leading and trailing edges of the tread material wound on the base tire.
