The seamless edge-sealing method of fluorine resin coating comprises following steps: (I) Putting the raw material of fluorine resin into a mold to obtain a cylinder (1) through one of the below ways: First, pressure maintaining and demolding, finally sintering the mold formed casting; Second, mechanical injecting; Third, mechanical vulcanizing; (II) Cutting the cylinder (1) into rings (3) and cutting each ring (3) to form an annular slot (31) on the inner wall of each ring; (III) Cutting a piece of base fabric of fluorine resin coating (2) into the shape adapted for the ring (3), and then stuffing the edge of the cut fabric of fluorine resin coating into the slot (31) of the ring; (IV) After hot-pressing, obtaining a piece of fabric of fluorine resin coating (4).

L'invention porte sur un procédé de scellement étanche de bord sans soudure à film fluororésine comprenant les étapes suivantes : 1. la disposition d'un matériau de fluororésine dans le moule, de façon à obtenir un corps tubulaire (1) de l'une des façons suivantes : la première façon consistant à maintenir une pression, à démouler, et, finalement, à fritter le moulage moulé par compression; la deuxième façon consistant à effectuer une injection mécanique; et la troisième façon consistant à effectuer une vulcanisation mécanique; 2. la coupe du corps tubulaire obtenu (1) en anneaux (3), et la découpe d'une fente annulaire (31) dans la paroi interne de l'anneau (3); 3. la coupe du tissu revêtu de fluororésine (2) sous une forme adaptée à l'anneau (3), et l'insertion du tissu dans la fente (31) de l'anneau (3); 4. le pressage à chaud de façon à acquérir un tissu revêtu de fluororésine (4) avec un bord étanchement scellé sans soudure.
