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.

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.

Abstract: PURPOSE:To effectively adhere a striplike member with a simple structure by providing a sponge roller for pressing and adhering the member to a cylindrical drum, and moving means for moving the roller to protrude it to the outer peripheral edge of the drum. CONSTITUTION:When a rotary rod 43 is rotated down from a state that the rod 43 presses a rubber sheet 3 to a table plate 9 and a cylinder 22 is driven to make a sponge roller 33 protrude, a sponge roller 33 for moving the end of the sheet 3 folded on a table plate 9 is developed forward while rotating, the end of the sheet 3 is effectively brought to the edge of the outer periphery of a molding drum 2, and the roller 33 presses the end to the drum 2. Accordingly, the end of the sheet 3 is adhered to the drum 2, and when the drum 2 is rotated in a state that the roller 3 is pressed on the sheet 3, the sheet 3 can be wound on the drum while being adhered thereto by the roller 3.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for cutting off a vulcanized tread member, by which the tread member can be efficiently and properly cut off at a proper position by using a simple structure. SOLUTION: When the vulcanized tread member 1 continuously vulcanized and formed into a belt shape is carried from the cut-off position and is cut off such that a tread pattern at the trailing edge part matches with a tread pattern at the leading edge to be joined with the trailing edge, a laser displacement sensor 20 is fixed to the same position as the position of a cutting-off device 30 in order to detect the position of the pattern to be cut off by measuring the undulation of the pattern block of the tread member 1 being carried, and in order to cut off the tread member 1 at that position.

Abstract: PROBLEM TO BE SOLVED: To provide a method for precisely grasping a position of a tread pattern for a vulcanized tread member to be conveyed and conveying the tread member to an appropriate cutting position to cut it. SOLUTION: A position of a pattern for a tread pattern image obtained by photographing a tread pattern at a position scheduled for cutting the tread member with the help of a photographing member is collated with a position of a frame 22B for a previously stored tread pattern image and thereby an amount of deviation A between both positions is detected. In addition, when the tread member is cut by moving the tread member or a cutting device by the detected amount of deviation A, the length of the frame 22B indicating a position of a pattern for the photographed tread pattern image is set larger by one pitch (P) than the length of the frame 22A for the stored tread pattern image.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for retreading for realizing a suitable front and rear end connecting state by adopting pattern aligning without irregular wear or without release of a connecting part, and automatically efficiently regulating an elongation or a contraction of a tread member at a winding time in the pattern aligning over an entire length in a uniform state. SOLUTION: The method for retreading comprises the steps of detecting a deviation amount (d) of a position of a necessary length of a tread from a distal end of a vulcanized tread member continued in a band-like state and vulcanized and molded from a predetermined position of the pattern to be cut near the same position as the position of the necessary length of the tread, cutting the member at the predetermined position of the pattern, substantially uniformly giving a tension or a compression to the tread member Tpc cut so as to eliminate the deviation amount (d), winding the member Tpc on the outer periphery of a trapezoidal tire T3 while regulating the length of the tread, and connecting the front end and the rear end of the wound member Tpc.
