（特公平３−２９５７５号公報）。2. Description of the Related Art Conventionally, rubber sheets have been manufactured by calender molding or press molding. However, when trying to obtain an ultra-thin rubber sheet, in calendering, when the rubber sheet is pulled out from the calender roll, there is a problem that the rubber sheet is stretched or cut, and is taken up by the roll and wound. However, it was difficult to obtain a thinner rubber sheet. In order to solve this, a method of manufacturing an ultra-thin rubber sheet using release paper has been proposed (Japanese Patent Publication No. 3-29575).

分には解決されていない。According to the above method, an extremely thin rubber sheet can be obtained even by calendering. However, since release paper cannot be used repeatedly, it is expensive and economical. There was a problem. In addition, because the release paper is smooth, the adhesion between the release paper and the rubber is poor during transfer between the release paper and the rubber, and the floating between the release paper and the rubber sheet, air loading, and air entrainment in the rubber are likely to occur. However, problems such as not being smooth and winding around a roll have not been sufficiently solved.

When an ultra-thin rubber sheet is obtained by calendering, there is no wrapping around a roll, and there is no floating between the release paper and the rubber sheet or air load. It is another object of the present invention to provide a manufacturing method capable of economically obtaining a sheet having no air entrainment in rubber, not wrapping around a roll, smoothly drawing out, and having a good finished appearance and feel.

The calender roll machine includes a side roll 10, a top roll 20, a center roll 30, a bottom roll 40, and a rubber roll 50. Kneaded rubber 60
Are sequentially passed between the rolls 10 and 20, between the rolls 20 and 30, and between the rolls 30 and 40.
Rolling is performed in a stage to form a sheet having a uniform rubber thickness. The rolls 10 and 20 are slightly thicker than the thickness of the rubber sheet to be obtained, and are rolled to about 2.0 to 1.5 times. ~
It is preferable to make it about 1.2 times. Then, a predetermined thickness between the roll 30 and the roll 40 may be set. Rolling may be performed in two stages, but by rolling the film little by little in three stages, the thickness of the sheet can be made more uniform.

返し使用が可能であり、非常に経済的である。[0007] In this manner, the rubber sheet rolled to a predetermined rubber thickness is transferred between the fed fabric liner 70 and the rolls 40 and 50. As the fabric liner, a fabric using a filament yarn such as nylon, polyester, rayon, acetate, or silk is used. In particular, a yarn having a density of 180 to 220 fibers / inch is driven by driving a yarn of 70 to 75 de of nylon or polyester. preferable. Further, as the fabric liner, a fabric obtained by treating these fabrics so as to have releasability, such as a fluorine process or a silicon resin process, can be used. By using such a fabric liner, it is possible to improve the adhesiveness with the rubber at the time of transfer with the rubber, eliminate the floating between the fabric liner and the rubber sheet, the occurrence of air load, the occurrence of air entrainment in the rubber, and pull out the drawer. This makes it possible to obtain an extremely thin rubber sheet which can be easily made and has a good finished appearance and feel. Further, the fabric can be repeatedly used unlike the release paper, and is very economical.

のである。After the rubber and the fabric liner are transferred between the rolls 40 and 50, they are pulled out and vulcanized ,
By peeling the textile liner , an ultra-thin rubber sheet can be obtained continuously. Even if vulcanization is carried out in-line with a continuous vulcanizer such as a pin vulcanizer, which is an existing vulcanizing vulcanizer, it is transferred to a fabric liner and wound into a sheet as unvulcanized. This is later vulcanized, may be carried out by a method called rolled vulcanization, but continuous vulcanization by a vulcanizing apparatus for drawing cloth,
It is effective in terms of efficiency and cost. According to the present invention, an ultra-thin rubber sheet having a thickness of 1.0 mm or less and up to about 0.1 mm can be obtained by calendering, and can be continuously produced. The ultra-thin rubber sheet thus obtained has an uneven pattern made of cloth on the rubber surface. Thereby, even after peeling off the fabric liner, there is no sticking between rubbers, and the sheet is very easy to handle. Also,
An extremely thin rubber sheet having a good finished appearance and a good feel can be obtained. Further, when the ultra-thin rubber sheet is used by being bonded to another material, the adhesiveness can be improved by the anchor effect. Further, since it is very difficult to process such a concavo-convex pattern on a rubber sheet later, the method of the present invention is very useful for obtaining an ultra-thin rubber sheet having a concavo-convex pattern.

A fabric liner may be transferred to both sides. FIG. 2 shows a schematic diagram of the manufacturing method in this case. In this case, after being transferred to the cloth liner 71 sent between the rolls 30 and 40, the cloth liner is further transferred to the untransferred rubber surface of the cloth liner between the rolls 40 and 50. The fabric liner 72 is transferred. The ultra-thin rubber sheet obtained in this way has a concave-convex pattern on both sides.

に経済的である。In the present invention, when obtaining an extremely thin rubber sheet by calendering, a cloth liner is used instead of smooth release paper. Conventional release paper has a smooth surface and poor adhesion to rubber, so it is taken up by rolls and wrapped around, floating between the rubber and release paper, air load, air entrainment in rubber is inevitable, and drawer It was not smooth. However, in the present invention, since the fabric liner is used, the adhesion to the rubber is good, and all of the above problems are solved. Further, since the rubber surface has an uneven pattern, a sheet having a good finished appearance and feel can be obtained, and the fabric can be repeatedly used, which is very economical.
