Due to this abrasion, the groove (tread pattern) provided on the tread tread becomes shallow, wet performance is deteriorated, and an accident may occur. Such worn tires are generally replaced, but for expensive tires such as trucks and buses, tires with worn tread treads can be regenerated to recover wet performance, etc. Is being extended.

ことにより加硫接着している。[0003] A generally used method for regenerating this tire is to form a base tire by removing the remaining tread portion of the worn tire with a buff to form an adhesive surface on the outer periphery of the tire. After arranging an unvulcanized rubber layer for adhesion, a pre-cure tread is attached to this, and after that, this is vulcanized and adhered by applying high pressure and high temperature in a vulcanization can.

構成されている。As mentioned above, when regenerating a tire,
The vulcanized precure tread is vulcanized and adhered to the base tire. As shown in FIG.
Has a tread tread surface 61 on the front side and an adhesive surface 62 to the base tire on the back surface side. The tread tread surface 61 is provided with a plurality of grooves (tread patterns) 63. When adhering the precure tread 60, it is necessary to form the adhering surface 62 of the precure tread 60 into a uniform rough surface. Explaining a conventional rough surface forming method together with a processing device, the rough surface is formed by buffing, and the buffing device includes a transfer conveyor 71 having a horizontal transfer surface 70, as shown in FIG. The processing head 73 is provided on the top of the transport surface 70 and has a buff wheel 72.

Then, the rotating buff wheel 72 is pressed against the precure tread 60, the precure tread 60 is fed in the direction of arrow BA, and when it is finished feeding, it is fed in the direction of AB. By repeating such an operation several times,
The adhesive surface 62 is buffed. Further, another example will be explained. As shown in FIG. 6, the sanding belt 75 is used with a processing tool in which a processing head 76 for running the sanding belt 75 is provided on a conveyor 71 similar to the above-mentioned conventional example. The difference was that.

れがある。However, if the above-mentioned conventional buffing apparatus is used to buff the adhesive surface, the following problems will occur. That is, since the tread surface has grooves forming a pattern, the buff surface has uneven rigidity, and the sanding belt or buff wheel uniformly presses the adhesive surface to buff it. Even if you do, the back surface of the bottom of the pattern groove has low rigidity, so it locally deforms and escapes, buffing is not performed, buff residue occurs, and there is a risk of a non-uniformly buffed adhesive surface There is.

のが現状である。If the buffed surface becomes non-uniform in this way, the adhesive strength between the base tire and the precure tread cannot be made uniform over the entire surface, which may impair the reliability of the retreaded tire. Therefore, conventionally, since the above-mentioned buff remaining portion is manually corrected and the above-mentioned bonding is performed, there is a problem in that productivity is significantly impaired and cost is increased.

To a predetermined interval and rotate. As soon as it is ready for processing, place the tread 60 on the belt between the pulleys 12b and 12c, and place the tread 6 on the buff wheel 18.
Transfer 0. When sequentially transferred and the tip of the tread 60 is inserted between the buff wheel 18 and the receiving pulley 12c, the tread 60 is bent along the receiving pulley 12c and is partially raised. The front end is further transferred and sent downward, and the rear end of the tread 60 passes through the buff wheel 18 and separates to the left.

Although tension is generated on the outer surface, since it is bent into a semi-cylindrical shape, the rigidity of the bottom of the groove 63 of the inner pattern is also increased, and a uniform reaction force is applied to the pressing force during processing. It will be in a state of being stuck. Due to this uniform reaction force, uniform buffing is performed, and no buff left portion or the like is generated. In this way, the tread 60 is reciprocated between the buff wheel 18 and the receiving pulley 12c a plurality of times for buffing.

The same parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. As in the first embodiment, this modification is composed of a transfer means 20 and a buffing means 25. Concerning the transfer means 20, the conveyor 11 is the same as that of the first embodiment, except that pressing rollers 13 are provided on both sides of the receiving pulley 12c. When the pressing roller 13 is provided in this way,
It is possible to reliably bend the tread 60 into a raised shape. Therefore, a larger reaction force can be applied to the first embodiment.

The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. This modification is composed of a transfer means 30 and a buffing means 35. The transfer means 30 is different from that of the first embodiment in that the receiving pulley 12 is supported by the air-cylinder device 14 and the pressing roller 1 supported by the air-cylinder device 15.
6 is different in that it is provided with 6. That is, since the receiving roller 12c is supported by the air-cylinder device 31, the working pressure and the stroke can be adjusted in consideration of the thickness and rigidity of the tread 60. Further, even when attached to the pressing roller 33, the pressing strength and stroke can be adjusted in consideration of the thickness and rigidity of the tread 60, so that various treads 60 can be easily accommodated. Further, the buffing means 35 is
Since it is the same as the first embodiment, detailed description thereof will be omitted.

On both sides of the conveyor 42a for loading and unloading,
42b is provided, and a pair of pressing rollers 43 is further arranged. Since the buffing means 45 is the same as that of the first embodiment, the same parts are designated by the same reference numerals and detailed description thereof will be omitted.

れる。More specifically, the process sequence of the method of the present invention is as follows:
It is placed on 2e with the adhesive surface 62 facing up. (2) The conveyor 11 is operated to feed the tread 60 toward the buff wheel 18. (3) When the tip of the tread 60 has passed the holding roller 33 on the left side of the drawing, the receiving roller 12c is raised by the air-cylinder 31 so that both air-cylinders 3
By lowering the pressing roller 33 by 2, the tread 60 is bent in a protruding shape. By bending in this manner, the inside of the tread 60, in particular, the rigidity including the bottom of the pattern groove 63 is increased. (4) Buff Hoi
Rotate the le 18 and buff. Buff 18 at this time
Although the adhesive surface 62 is pressed by, the reaction force uniformly opposes the processing pressure to the adhesive surface 62, which is the surface to be buffed of the tread 60 having increased rigidity, so that the buff is uniformly processed and the buff remains. No part occurs. (5) After the rear end of the tread 60 has passed the receiving roller 12c, the pressing roller 33,
The receiving roller 12c is returned to its original position. By repeating such an operation and reciprocating a plurality of times, a good buffed surface can be obtained.
