境対策としてシートをカラー化する傾向になっている。Lately, antistatic mats in the form of rubber sheets have come into use as antistatic products. This antistatic cloak is processed by press molding in a small size, and a long sheet type is manufactured by a continuous press or rotary vulcanizer. In particular, recently there has been an increasing demand for mats that can be laid across the floors of factories related to light electrical appliances for the purpose of reducing electricity consumption.
For this reason, long sheets have become mainstream. Additionally, as an environmental measure, there is a trend towards colorized sheets.

り製造する方法等が考えられる。A rotary vulcanization method is a reasonable method for vulcanizing an antistatic rubber sheet while maintaining uniform quality. In general, notebooks vulcanized with a rotary vulcanizer have a mirror finish, and if the vulcanized sheet is wound into a roll as it is, there is a problem in that blocking occurs in the rubber sheet. Normally, the mirror surface of the sort is coated with a mold release agent or dusted with powder to prevent blocking. However, if the surface of a sheet installed as an anti-static mano on the floor of a factory related to light electrical appliances, which requires a clean environment, is dusted, it is not preferable because it causes dust to be generated. Moreover, it will have an adverse effect on conductivity. Another method for preventing blocking on the surface of a rolled rubber sheet without resorting to dusting or application of a release agent is to select a compounding agent when designing the compounding of the sheet material. For example, the method includes the use of silicone-based combs, fluorine-based combs, etc., the addition of wax or paraffin-based lubricants, or the addition of a silicone-based or fluorine-based mold release agent itself to the compounding agent. However, these substances are all components that have a negative effect on conductivity.
Therefore, even when using this method, it is difficult to realize it in practice due to constraints on the design of the ingredients. Yet another method for preventing blocking is to reduce the contact area by adding finely textured texture to the surface of the rubber sheet. When this method is used, the above-mentioned gap (m) does not occur, and it is extremely effective as a method for manufacturing a conductive sheet. A conventional and generally known method for producing finely uneven textured surfaces on the surface of a rubber sheet is to apply the textured texture to the surface of a press mold by pressing a molding material to form the textured texture into a sheet. Another known method is to insert a release base rubber with a textured surface between a mold and a rubber sheet, and then transfer the texture of the release sheet to the rubber sheet by press processing. Possible methods for obtaining shaku sheets include a main roll with an engosed surface, or a method in which a rubber sheet is pressed against the surface of the main roll to give a textured surface to the surface of a steel belt that provides continuous feeding, and is produced by a funnel flow method. It will be done.

のシボ肌の汚染が著しい。However, when using the Sores molding machine, the transfer is inevitably repeated for each fixed area, resulting in deviations in the transfer of the boundary line, and when using press processing, pressure due to the vertical movement of the ram, especially on the machined surface during the return process, is affected. There is a drawback that it is difficult to obtain a uniform grained surface due to the suction force that is applied. On the other hand, when using the rotary vulcanization method, the transfer surface of the main roll or belt is used repeatedly, so that the grained surface of the transfer surface is significantly contaminated.

る。Since this dirt on the grained skin is printed as is, it is difficult to obtain a grained skin with uniform quality and excellent appearance. Furthermore, it is extremely difficult to clean the transfer surfaces of the main roll and belt during continuous production, especially the transfer surfaces with fine grain texture. In addition, skin damage due to pollution, etc.
If wear occurs, this requires extensive replacement work.

ト又はゴム引布の連続製造方法である。The present invention provides a processing sheet such as a rubber sheet or rubberized cloth between a main roll heated to a high temperature and a belt that is continuously fed along its circumferential surface, and a transfer sheet with a textured surface. While the main roll rotates and feeds the sheet to be processed along its circumferential surface, the texture of the transfer sheet is transferred to the surface of the sheet and vulcanization is performed. This is a continuous manufacturing method for a rubber sheet or rubberized cloth having a textured surface, which is characterized by pulling out the sheet in the tangential direction of the main roll, inverting the backing sheet, and peeling it off from the transfer sheet.

ート７に作用して引き裂かれるようなことはない。In the case of actual regret, an IJ with a finely textured texture applied to one side of the applied air trowel, such as a rubber sheet or rubberized cloth.
- Layer a transfer sheet 7 such as one piece or raw cloth on the base, place the transfer sheet 7 along the main roll 10 side, and insert the laminated sheet between the main roll 1 and the belt 5 from the first guide roll 2 side. Send. By the rotation of the main roll 1, the toner and the transfer sheet 7 are drawn onto the circumferential surface thereof, and vulcanization progresses under the heat of the heating device, and the vulcanization is applied to the transfer sheet 7 by pressure from the belt 5 side. The grain is transferred to the surface of the applied grain. The laminated sheet that has passed around the circumference of the main roll 1 has been vulcanized and transferred, and the second sheet has reached the idle roll 3 side. This laminated sheet is separated into the applied sheet and the transfer sheet 7, and the transfer sheet 7 is pulled out in the tangential direction of the main roll 1, and the applied sheet is reversed and cooled through the circumferential surface of the second guide roll 3, and then rolled. Roll it into a shape. In the present invention, the transfer sheet 7 is superimposed on the steel belt 5 supported by both guide rolls 2.3.
is held between the main roll 1 and the belt 5.
Continuous feeding is applied along the circumferential surface of the main roll 10 while receiving pressure from
Since it is pulled away from the applied roller at a position beyond the second guide roll 3 and then pulled out in the tangential direction of the main roll 1, it will not be forced to peel, and excessive tension will act on the transfer sheet 7 and tear it. There's no way you'll be disappointed.

ばよい。In addition, when the laminated sheet rotates around the circumferential surface of the main roll 1, the transfer sheet 7 is on the inside and the applied material is on the outside, and the thick material is forcibly bent inward and deeply wedged into the grains of the transfer sheet 7. , precise transcription becomes possible. However, if fine grains are to be added to both sides of the applied roller, it is of course possible to insert a second transfer sheet 8 between the applied roller and the steel belt 5 to transfer the texture, as shown in Fig. 2. . In this case, first, the inner transfer sheet 7 is separated from the circumferential surface of the main roll 1, and then the laminated sheet of the applied transfer sheet 8 and the reversed transfer sheet is placed on the circumferential surface of the second guide roll 3. The transfer sheet 7 may be peeled off in the tangential direction of the second guide roll 3, and the transferred sheet may be reversed onto the peripheral surface of the auxiliary roll 90.
