Zusammenfassung:	PURPOSE:To obtain a joint sheet which has excellent tensile strength, processability, and workability and is made without asbestos, by mixing sepiolite, a rubber material, and rubber chemicals. CONSTITUTION:10-70wt% fibrous sepiolite (A), as base fiber, of a length of 5-3,000mum, preferably 20-100mum, is mixed with 10-40wt% rubber material (B) (e.g., nitrile rubber); 0.5-20wt% rubber chemicals (C) which comprise a vulcanizing agent, such as S, ZnO or MgO, and a vulcanization accelerator, such as a thiazole compound, a polyamine compound or a sulfenamide compound; and if necessary, 0-80wt% inorganic fibers (e.g., glass fibers), organic fibers (e.g., fibrillated aromatic polyamide fibers), and filler (e.g., clay), and 0.1-10wt% organic antistatic agent (e.g., lauryltrimethylammonium chloride). This mixture is dissolved in a solvent for rubber material (e.g., toluene) and is put between a hot roll at 120-160 deg.C and cold roll at 50 deg.C or lower to be heated and rolled.
