摘要： PROBLEM TO BE SOLVED: To measure a tire-uniformity value stably and with high accuracy by a method wherein, when a measured internal-pressure change value is at a set value or higher, an abnormality is judged. SOLUTION: The air is introduced into a tire 1 which is held by a rim 2 and a rim 3 via a pipe 6. A change in the internal pressure of the tire 1 into which the air is introduced is measured by a measuring means 10. A change value which is measured by the measuring means 10 is compared with a set value which is set in advance. When the change value is at the set value or higher, an abnormality is judged by a judgment means 11. Then, a measuring apparatus is stopped by a stop means 12. The measuring means 10 is composed of, e.g. a pressure sensor or the like using a strain gage, and a measured value from the pressure detecting sensor is input to the judgment means 11. In addition, the judgment means 11 is composed of, e.g. a personal computer or the like. A set value which is set in advance is compared with the measured value by the judgment means 11. When the measured value exceeds the set value, an abnormality signal is input to the stop means 12. The stop means 12 stops the drive of the measuring apparatus.

摘要： PROBLEM TO BE SOLVED: To precisely inspect the position of a centerline by comparatively calculating the calculated value of a marker end point by a camera image and the calculated value of an application gun position to calculate the off-center quantity. SOLUTION: To a strip tire member 1, a light laid along its lateral direction is emitted from a light emitting means 3. The image of a centerline 2 taken by a camera 4 is binarized by an image processing device 11, and two end points of a marker by the light emitting means 3 are calculated by a first calculating means 6, and the position of a centerline application gun 7 is calculated by a second calculating means 8. The calculated value of the first calculating means 6 and the calculated value of the second calculating means 8 are comparatively calculated to calculate the off-center quantity of the centerline 2 by an arithmetic means 9, and the position of the centerline application gun 7 is corrected by a control means 10 on the basis of the arithmetic value. The first and second calculating means 6, 8 are involved in the image processing device 11, and the arithmetic means 9 is involved in a personal computer 12.

摘要： PROBLEM TO BE SOLVED: To adjust the pressing width of the weight aggregate on an adhesive coating roll and to improve coating efficiency by inserting a movably supported fork from the outer end of the weight aggregate and detaining the outer weight disk with an inner weight disk. SOLUTION: The presser 5 of an adhesive coater 1 is divided into both outer weight disk group 21 with its weight aggregate 4 detained by a fork 6 and a weight disk group 21 hung inside. The entire width of a band K is pressed on an adhesive coating roller 3 by the inner weight disk group 21 to coat the lower face of the band K with an adhesive J. At this time, the width of the band K is inputted to the coater 1, hence the driving screw shaft 27 in a moving fork part 7 is rotated, a bracket 25 is moved, and fork 6 is inserted into the insertion length corresponding to a necessary pressing width W. Subsequently, the driving part 32 of a leveler 10 is driven to retreat a receiving dish 31, and the presser 5 is lowered.

摘要： PURPOSE:To prevent wires from being crossed one another, and enable uniform corrugation by carrying out corrugation and lateral-throwing down in use of a wire sheet which is molded into a sheet in covering a plurality of wires with an elastic material. CONSTITUTION:By forming a wire sheet 3 in covering a plurality of hard wires 4 with an elastic material such as unvulcanized rubber or the like, when the wires 4 corrugated in a longitudinal wave manner are laterally thrown down, an elastic covering material takes in the distortion of the wires 4, so that they can be laterally thrown down in flatness. And the laterally thrown down wires 4 are restrained by the plasticizing properties of the unvulcanized rubber, thus the wires keep the laterally thrown down state. And respective wires are restrained in their movement by the elastic material 5. Whereby respective positional relations among mutual wires are kept constant, and there never occurs wire-crossing therein. And, since the difference in stretching force among the wires is taken in by the elastic material uniform 5, corrugation by use of a gear 6 can be conducted even if each tension of wires 4 in front and the behind of the gear 6 is not uniform.

摘要： PURPOSE:To keep the depth and breadth of groove in a tyre product constant even if the pitching of the tyre occurs by setting a cutter to theoretic cutter cutting position, and calculating the correction moving rate of the cutter by a tyre pitching detecting signal, and then actuating the moving rate correcting mechanism of a coming up and down table on the basis thereof. CONSTITUTION:In a standard actuation operating unit, a standard program is memorized therein, and according to this, the direction of a cutter 10 is set by making it coincide with the cutting direction by means of a motor 11, and then heated, wherein a tyre 3 is rotated, and further the standard rate moving mechanism of a coming up and down table driving mechanism 8 is driven so as to make a coming up and down table 7 descend in the direction of a Z axis, as a result, the cutter 10 cuts into the tyre 3 and the necessary grooving is conducted thereby. While a correcting program is memorized in a correcting operation unit, and in the case where pitching occurs due to the distortion in a tread surface of the tyre 3, the pitching is detected by means of a pitching detector 14, and the moving rate correcting mechanism of the coming up and down table 7 is driven in accordance with the correcting value from the correcting program on the basis thereof, and thus the cutter position is corrected and the depth is kept constant. Accordingly, the desired grooving can be performed even if any pitching occurs in the tyre.

摘要： PURPOSE:To omit the time and labor required in the replacement of a cutter to a large extent and to perform replacement work in such a state that the cutter is still hot, by dividing a cutter support device into a support rod, a cutter support frame and cutter holder having a cutter fixed thereto. CONSTITUTION:A cutter support device is divided into a cutter support frame 14 and the cutter holder 18 detachable to said cutter support frame 14. A cutter 9 of every kind subjected to bending processing at every desired groove shape is preliminarily inserted in the cutter holding groove of the clamp piece 20 of a separate cutter holder 18 and mounted thereto by a clamp screw 21 and a nut. At the time of the replacement of the cutter 9, the cutter holder 18 is detached and the separate cutter holder 18 equipped with the cutter 9 is inserted in the dovetail mount groove 15 of the cutter support frame 14 by the insulating base 16 thereof and a clamp piece 25 is fixed by a clamp screw.

摘要： PURPOSE:To process a desired pattern groove to a tread surface, by mounting a contact member for allowing a cutter to protrude corresponding to the predetermined depth of a pattern groove and providing an elastic member energizing the cutter between a cutter clamp and a cutter support frame in a direction for bringing the same into contact with a tire to move the cutter by an elastic member apart from the movement of a cutter support apparatus so as to follow strain. CONSTITUTION:A tire 3 is mounted on a tire support stand 2 and positioned by moving a support truck on a rail 21 in an X-axis direction by an operation apparatus not shown in a drawing and moving the same on a rail 22 in a Y-axis direction. When the tread surface of the tire 3 is distorted and unevenness is generated from a reference surface shown by one-dot broken line, since a contact member 12 is brought into contact with the tread surface, a cutter clamp 86 allows an elastic member 9 to extend and contract corresponding to longitudinal vibration due to the unevenness to allow a cutter 10 to always move up and down so as to follow the tread surface and the depth of a groove to be formed is kept constant to prevent the generation of a shallow or deep part in the groove.
